Butler:
Today is September 12, 2000. This oral history with Andrew Hobokan
is being conducted for the Johnson Space Center Oral History Project
at the offices of the Signal Corporation. Carol Butler is the interviewer
and is assisted by Kevin Rusnak.
Hobokan:
…John [F.] Yardley was McDonnell’s [Aircraft Corporation]
kingpin at Cape Canaveral [Florida]. That’s Cape Canaveral Air
Force Station, not KSC [Kennedy Space Center]. There’s a difference
between the two. Anyway, Yardley was down. The launch group had some
pretty aggressive people on the staff. G. Merritt Preston, for instance,
you’ve probably heard of him. He was pushing a good launch staff,
okay, but he was also wanting to take over other people’s functions,
and he had a good test team. He had a couple of men there like Ted
[George T.] Sasseen, who was very good at test. I enjoyed working
with him in his career at KSC.
But we never had a full spacecraft in [McDonnell at] St. Louis [Missouri]
because the KSC guys like Preston would get on Yardley and say, “Hey,
look. We've got to have the instrumentation to see if we can [unclear]
the blockhouse.” So without the instrumentation at St. Louis,
you could never really check out the vehicle. So we tested as well
as we could, and then the vehicle was shipped to KSC, where they put
the instrumentation package and they did the altitude chambers test
with the crew. They did the complete check-out and put it on the launch
vehicle and launched it.
So basically a large part of this task of finishing the spacecraft
was done by KSC. When it was launched, people at St. Louis were aghast
at some of the temperatures and pressures they were reading, because
where they designed the instrumentation in—gosh, KSC, with John
Yardley, moved it where they thought it ought to be. So you thought
you had a temperature sensor around the heat shield, it might wind
up around a parachute box, okay, the parachute container. So you never
knew when you launched it whether you were going to see what you expected
to see, and that was very frustrating to the design people in St.
Louis. This information never flowed back into St. Louis before the
launch.
So there was a big flap in St. Louis about how do we fix this problem?
The big hue and cry was, “We’ll get John Yardley out of
there,” but they weren’t ready for that yet. They weren’t
ready for that major move yet. They really needed him down there because
he was well in with the launch people and was a pretty good manager
down there and was taking care of things very well.
But then after we launched—I guess it was after we launched
Gus [Virgil I.] Grissom, McDonnell pushed for the Gemini Program to
do a bigger job. Now, here was a case where President [John F.] Kennedy
had said, “Let’s land a man on the Moon and return him
safely to Earth.” Well, that started Apollo.
Just before that—well, let me back up just a little bit. During
the course of the Mercury Program, the Space Task Group opened an
office down here on OST. It was a realtor’s building that was
taken over, and it had maybe eight or ten little offices. So some
of the Langley people came to OST, and I came down there a couple
of times, and it was a little small operation. Then toward the time
of Mercury, where we were launching people after [John H.] Glenn,
they moved to I-45, out to this little oil derrick place on I-45.
That was a lot space for a lot more people so it was expanding. If
I remember correctly, that’s when Apollo started and Mercury
was phasing out.
But when Apollo started, the job was formidable. McDonnell came in
with a proposal, had come in with a proposal as a follow-on to Mercury
going to the Gemini Program, two men in space. It became the pathfinder,
really a pathfinder for Apollo. As Apollo was being formulated, things
like docking came up. So Gemini was given the assignment, you know,
do a docking. Things like firing a rocket in orbit came up, so we
had the Gemini Centaur, I think it was, Gemini—
Butler:
The Agena?
Hobokan:
Agena. Yes, the Gemini Agena came up, so we would demonstrate that
you could fire a rocket in space and you could rendezvous with it,
latch onto it, and that kind of thing. So Gemini was doing the pathfinder
work. For instance, the heat shield for the CSM [Command and Service
Module] came out of the Gemini heat shield. We made samples of the
Gemini heat shield, oh, two and half inches or three inches thick,
and delivered them to [North American] Rockwell. Then you see the
honeycomb appeared on the outside of the command module. But that
was the way the heat shield was made on Gemini.
After the fire, we delivered all the latching mechanisms for the hatch
to Rockwell, and they made a hatch similar, a quick-opening hatch.
But then we found out on Gemini we didn’t have a quick-opening
hatch anyway. The hatch lever had to be cranked, and you had a pole.
You had to move a pole to, say, latch it closed, and you had to move
it to neutral in flight, and then when you want to open it, you had
to move to “open” and rachet it open. So we didn’t
have a handle where you could hit it and the hatch opened. But we
did have the ejection seat concept, and we didn’t use the escape
tower.
So Gemini did many of the things that contributed to Apollo. It really
was pretty good pathfinder. When the Gemini Program was ending, we
proposed to go out and get a big rocket and do a large Earth orbit,
and that proposal got shot down, but the fact that there weren’t
any lunar modules, the Apollo did it. It [Apollo 8] went around the
Moon on that Christmas Eve. But we were planning do that, we really
were.
The time that we were building the Geminis, we really got well into
the quality and the reliability and the safety aspects of the space
program. Things were going on down here at JSC [Johnson Space Center,
Houston, Texas], and they were forming the SR&QA [Safety, Reliability,
and Quality Assurance] department down here, and they were adopting
a lot of the things we were doing and embellishing the things we were
doing. So we developed a whole SR&QA operation via the Gemini
Program, and then it was applied to everything else.
The Gemini Program was really an interesting program. We did, like
on GT-IV [Gemini-Titan IV], Ed [Edward H.] White’s first EVA.
It was interesting that nobody had opened the spacecraft up at high
altitude in an altitude chamber. I was saying we ought to go and test
this concept. We starting writing a procedure for opening the hatch
and checking the EVA capability of the suit and so forth. But he wasn’t
going to get out. It was a case of just opening the hatch in that
environment and have him go on an umbilical and wave his little propulsion
system around. But word got out and we got a call from Dr. [Robert
R.] Gilruth to "Come down to Houston and explain what you’re
doing." [Laughter]
So I got the job of coming down here to make a pitch to Dr. Gilruth
and the team at what was now Manned Spacecraft Center [Houston, TX,
later JSC]. Dr. [Charles A.] Berry was there, and Dr. Berry was objecting
to us doing this in the altitude chamber. So I said, “If you’re
afraid to do it in the altitude chamber where I have complete control
of everything, what makes you think you want to do this out in space
where you don’t have any control?”
Well, Dr. Gilruth said, “Let’s take a little break here,”
and he says, “Dr. Berry, I’d like to see you in my office.”
Five minutes later when they came out, he said, “Dr. Berry’s
got something to say.”
Dr. Berry said, “I don’t think we ought to do this out
in space unless we first do it under good controlled conditions."
So I got to go home and we got to set up the altitude chamber for
that. Then we put all of the crews through that. We never had a problem.
There were three things that really were worrisome. Number one, if
you aborted somebody during this operation and you blew the altitude
chamber all the way down to the ground, you broke his ear drums, you
know. If you really did that to crew members, it’s a bad thing.
So in development our procedure we had a—the spacecraft was
at 5 psi [pounds per square inch]. That was equivalent to about 30,000
feet of altitude. So we put an addendum to the chamber. At 30,000
feet it was at 5 psi. So now we put a rescue crew in there—a
medic, a doctor, and the rescue crew, and these guys were there all
the time. When Ed White was going up, they were in this 30,000-foot
altitude chamber.
We had an abort mode that we could blow it to 5 psi, and these guys
could get in there and then take them out, and then they could lower
them down in that little altitude chamber while they were taking care
of them. The abort mode that blew them all the way to the ground,
we never planned to use it, but it was a last resort.
We didn’t have a problem until Dick [Richard F.] Gordon’s
flight. I think it was Gemini X. We got Dick Gordon up there at high
altitude, and we opened the hatch. I think the test conductor guy’s
name was Parker. He was a McDonnell employee. Dr. Hawkins and I were
listening on the earpiece. Dr. Hawkins was listening to heart beats,
heart rates, whatever the doctors did at that time, and I was listening
to some of the technical stuff. Suddenly I hear somebody say, “Suit
pressure, 4.8. Suit pressure, 4.6. Suit pressure, 4.4."
And I got up and I went over to the test conductor and I said, “You’re
hearing this?”
He said, “Yes."
I said, “What abort mode are you going to pull?”
He said, “30,000. You do it to 30,000 feet where we got the
crew."
And I said, “No less than 3.4 psi in that suit.” That’s
equivalent to something less than 62,000 feet. If you get to 3.2,
I believe it is, your blood boils. You’d kill him anyway.
So, anyway, the suit pressure was coming down, and the engineers were
trying to figure out what was going on. Finally it got low enough,
he looked at me and I looked at him, and he aborted.
So we got Dick Gordon out there, and his arms are wide like this because
of the suit pressure, and somebody said, “Hey, there’s
a wire missing out of the umbilical.” The wire that’s
supposed to carry the suit pressure wasn’t in the JSC-supplied
umbilical. It was a Manned Spacecraft Center-supplied umbilical. So
when he switched it, all we had was the energy drooping down from
the spacecraft plug-in, all right. He was there at 30,000 feet and
everything was all right, and I said, “Dick, do you want to
go back up?”
He said, “No.” He said, “You guys do the rest of
it unmanned.” So that was the only problem we ever had in the
altitude chamber, and it was benign, but it scared the heck out of
a lot of us.
We put twenty-four crews through there, I believe, yes, twenty-four
crews through that altitude chamber testing it, St. Louis, but we
delivered spacecraft that were really finished, not like Mercury.
They were really finished and they flew well, and we had a great rapport
between the contractor and the resident office. Now, we had a good
staff, good staff, and the president, Walter F. Burke, and I became
great friends. We argued a lot about design and we argued a lot about
his facilities. I’d get questions from him that said, “Whose
facility is this, anyway?”
On Gemini we had a problem when they brought up rendezvous, and that’s
the first time I heard of “launch window.” I said, “What
do you mean, launch window?”
“Well, we have to launch in a short period of time to be able
to rendezvous with the target without burning a lot of fuel.”
I said, “Gee, you know, we’re sitting down here with all
of our equipment. Somebody’s turning a knob. Somebody’s
reading it. Somebody’s writing it down. How are we ever going
to launch in a ten-minute window? It takes us ten minutes just to
make one measurement.”
So I started looking at automatic test equipment for that period of
time. Anyway, we did a lot of phone calling, and the Air Force had
a plant out in Titaboro [phonetic], New Jersey, that was making a
tape machine for automatic checkout of a rocket. I think it was Minuteman
or something. I said, “Gee, it would be nice if we’d get
one of those machines and see if we could do it on the Gemini Program.”
We had a priority that was higher than the Air Force when I’ve
checked into it. We had a DX-A2 or something, and the Air Force program
was a lesser priority.
So I got with Art Atkinson, and I said, “Art, place an order
for one of those and use our priority.” Well, they pulled the
ones off the production line and shipped it to us in St. Louis. We
had a compatibility test unit which was like a Gemini that we could
test the interfaces and all of the stuff.
Anyway, about three weeks after we got it, one of the secretaries
come out and said, “Dr. Gilruth’s on the phone. He wants
to talk to you.”
Well, the Air Force found out that we had pulled that unit out of
their production line, and they had filed a big complaint with Dr.
Gilruth, and Dr. Gilruth read me off up there, and he said, “Don’t
you ever do that again.”
But shortly thereafter, I got a call. I was made part of a team to
look into automatic checkout. So based on that, they had gotten some
KSC guys and some people from MSC and myself and a couple of Air Force
people, and they said, “Go look at this thing of automatic checkout.”
Well, the team flew to, I think it was Boeing was doing some work,
Lockheed [Aircraft Corporation] was doing some work, General Dynamics
[Corporation]was doing some work. So we got to fly around the country
and see what people were doing in the way of automatic checkout. And
we still piddling with this tape machine there in St. Louis.
The team decided if we’re going to do this, we ought to do it
with computers, not tape machines. So the team decided they were going
to buy two computers, or four computers, from CDC, Computer Data Corporation.
They bought the computers from CDC. They went to MSC, and the people
started playing with them, looking to see how they could do automatic
checkout.
Well, Chuck [Charles W.] Mathews was the manager of the Gemini Program.
The computers cost a lot. The people, the employees cost a lot. I
think the bill hit 14 million dollars, and he said, “I can’t
afford it anymore,” which was a pretty astute move, because
it was eating up project money. KSC people made a pitch to take the
equipment the way it was, all of it, and they would continue to go
for automatic checkout because they also had the problem on this launch.
You know, it wasn't only the contractor who had to supply the equipment;
they had to do it.
There was a guy named Jake Mosher [phonetic], worked for G. Merritt
Preston, and they hired General Electric, and they went with these
computers, and, by janes, they worked on it and worked on it and worked
on it. When Apollo came, they had an automatic checkout system that
GE could supply for Apollo. So the system turned out to be automatic
checkout for Downey [California, site of North American Rockwell]
and Grumman [Corporation] on the lunar module [LM], so that it all
wasn’t for naught. Chuck Mathews put in 14 million to get it
started, but the KSC guys really came through and for the Apollo Program
we did have automatic checkout.
But it was in octal. I go down there and look at these lights. You
had to read octal, and the guys who did it every day could read octal,
okay. An octal is when you have four lights in banks of four. Each
one gives you a number when you look at the bank of lights, whichever
ones are on or off that gives you the number for that batch. Well,
the people who use the machine were very comfortable with it. They
could read that stuff. They named it the ACE, Automatic Checkout Equipment.
So it was called the ACE.
Then KSC used some of those concepts on the launch site, and we, in
turn, up in the latter days of Gemini had some of the concepts put
to use there. So we were all leaning toward this thing that is now
called the LPS, the Launch Processing System at KSC. So that was a
real big development that came around. LPS got a big push, because
the people at which is now JSC were developing a system called the
UTE, called U-T-E, Unified Test Equipment. It was supposed to be helping
the factories, but like when you fill a tank, you see the tank fill
up, they had visual displays as well as accurate measurements of everything.
It showed you when the fuel flowing through the lines as valves were
opened. It was real interesting setup, but whether how practical it
was, you know, and it was another colored horse.
But we spent a lot of money. I was spending money with them to develop
this system, and finally KSC said, “Hey, that’s our job,
really.” So the UTE concept was given to KSC, too, and the LPS
came out of that thing. The LPS, Launch Processing Systems that’s
now in use, was also helped from the development of the UTE here at
JSC.
So that got everybody on the automatic checkout world. On Apollo,
everything was automatic down to two minutes, and then you have an
automatic sequence from their autosequence. It has enough checks and
balances so that if it sees something wrong, it can stop it. The space
shuttle uses the same concept.
Well, anyway, after Gemini was over, we were building the airlock
tunnel in the instrument room for Skylab, and these things were being
built in St. Louis. We had all kinds of problems. I’ve got all
kinds of samples of when you stow equipment—I don’t think
we had velcro at that time—when you stow equipment for launch,
the astronaut has to be able to get it out of there. So we had all
kinds of long-handled wrenches and things that we were practicing
with to try to find a way that you could have the equipment secured
for launch, but then easy for the crew to get out afterwards. It was
fun developing all of this. We’d go down in a tool room and
have people make tools for us, and we’d try them out and junk
them by the sixes. You know, you very seldom hit on a good idea right
off the bat. You try some things and slowly you evolved the one you
really want to use.
But it was this time that I got a call to—well, the fire happened.
The Apollo problem happened, okay. My boss, Wilbur H. Gray, got transferred
to Downey to be the resident manager at Downey. In those days, we
called the office the RASPO. We had the ASPO here at JSC, Apollo Spacecraft
Program Office, but the resident offices were Resident Apollo Spacecraft
Program Office. So Bill Gray got assigned to Downey. Bob Ridenour
[phonetic] shot himself or something, but I guess you got that in
your record somewhere. Okay. Well, Bill was assigned to take over
that job. That was before the fire. That was before the fire.
Anyway, Bill was trying to find a house, so he called me one day and
said, “I don’t want to leave the office empty for a week
or so while I’m looking for a house. Could you come out here
and sit in for me?” So I did that. I jumped on an airplane and
I went out there and I sat in his office for a few days while he was
out house-hunting. He had in his office a TV set. The TV set was always
on. It was hard-lined, and it was always on. I heard somebody say,
“Ed White was here,” and I looked up at the TV, and, hell,
here is a group of people out there with your cameras and—probably
that’s why I’m shy of some of the cameras—they were
saying this guy was laying, you know, like this in the seat and this
guy was over here.
I got up, and suddenly the guy said, “We’re coming to
you from the mockup room at Rockwell International in Downey, California.”
I got up out of my seat and I ran to the mockup room, and there they
were, photographing all of this stuff, and I thought that was pretty
raw. This was only like a day or so after the fire, and these guys
are putting this out on TV. So I said, “I want this operation
shut down.”
Well, the Rockwell said, “Who the heck are you?”
I said, “Right now, I’m the resident manager.”
So they said, “Well, we have permission from the company to
do this. This is our building.”
I said, “It’s not your building. This is my building.”
NASA owned that building, so I said, “This is our building.
It’s not your building.”
The guy said, “We got the permission from the President to do
this.”
I was standing next to a fire ax on the wall. I reached out and I
picked up the fire ax, and I raised it up. I said, “You either
shut down, or I’m going to give you your cables in one-foot
lengths.” Those cables are about that big around [Hobokan gestures],
and I know they’re costly, because at Patuxent [Naval Air Station,
Maryland] I had what they called a peanut system from Dumont [phonetic],
and I knew how expensive those cables were. Finally the guy shut it
down. But I was going to cut those cables.
I got back to my office, and I wasn’t there five minutes when
the phone rang, and, of course, it was Dr. Gilruth again. He said,
“Why am I always giving you hell?”
So I said, “I shut it down,” and I explained to him what
was going on.
He said, “Well, it’s good you shut it down. Keep it shut
down. Don’t let them do that.” So I got over that hurdle,
and it never came back on the air again.
Then Bill got his house and I went back to St. Louis. I hadn’t
been back very long and I got this phone call from Marilyn Bockting
down here. Marilyn Bockting happened to be George [M.] Low’s
secretary. She said, “Mr. Low wants to see you this afternoon.
Can you get on an airplane and get down here?” Well, I didn't
work for him. I worked for whomever was doing the Skylab, and I think
that at that time it was Bob [Robert F.] Thompson. So I was working
for Bob Thompson. What the heck does George Low want?
So I got out my TR [travel requisition?], book of TRs, and I went
on an airplane, and I came down here. I got down here about four o’clock
in the afternoon. I knew something was up, or I should have known
something was up. Marilyn Bockting handed me a cup of black coffee,
closed the door on her way out, and I go, "For crying out loud,
here I am in trouble again." I wondered what was going on, because
I didn’t have anything to do with Apollo other than supply those
items that I told you about, the heat shield and so forth. Now what
was this all about?
So stop here a minute. There was a guy named General Carroll [H. “Rip”]
Bolender. He worked for George Low. He had called me once before and
he asked me to go take a look at a manufacturing company out in California
that people at JSC said were doing a lousy job. He said, “I
want a second opinion. You go out there for me and look that over.”
Well, they were doing a great job. Just the fact that JSC wasn’t
helping them, JSC wanted to change contractors so they weren’t
helping, and they were allowing them to do welds which were called
unauthorized welds. Now, they weren’t unauthorized welds at
all. The weld procedure was agreed to by Grumman, who was the procurer
of those tanks, okay. JSC never approved of the weld procedure, so
they called them unauthorized welds and gave the company a bad name,
okay. The company’s name was Air-Right [phonetic], I believe.
Gave them a very bad name.
Anyway, I thought the company doing a bang-up job, so I told Bolender.
But the tank, they continued to make the tanks and when they did some
testing on the tanks, the tank burst, not because of the welds, but
because of the water that they used. It caused hydrogen embrittlement
of the titanium tank, and the tank burst. We didn’t have very
good fraction mechanics approach at that time. I have to come back
to this tank later.
Anyway, after I did that for him, he called me one day and he said,
“I want you to take a check on the Grumman operation. You got
a task there with the Skylab stuff, but can you spare some people
to go to Grumman and do a check on how the Grumman operation is going?”
So I sent five people out to Grumman under Bill Nesbitt [phonetic].
Bill Nesbitt was one of the original people on the STG. They were
there about a week, and I got this phone call that said, “I
want to come home. We can’t do anything here. We’re not
learning anything.”
I said, “What do you mean?”
He said, “Well, we can’t get schedules. We can’t
get drawings. We can't look at work orders.”
And I said, “But you guys have all the authority you need to
go do this stuff.”
He said, “Well, the company won’t cooperate.”
I said, “Stay there. I’ll get on an airplane and I’ll
come out and see what we can do.”
So I flew to Grumman on a Thursday, I guess it was, and I got with
my guys around the table. They were all telling what they can and
can’t do, and so I said, “Well, let’s go en masse.
We’ll just go out there and talk to the people.”
So we got out there and we tried to talk to the people. We tried to
find drawings. They didn’t have them. That’s why they
couldn’t cooperate. They didn’t have everything that they
needed to do to build these lunar modules. So I stayed.
General Bolender came up that night, and I called him and told him
that things were really, really bad, that I don’t know how they
knew what they were doing. So Bolender came up, and we went out to
dinner Friday evening, and we were just talking about things, and
I said, “Well, I’ll go home in the morning and then I’ll
write you a report.”
He said, “Oh, no. I don’t want you to write a report.”
He said, “I made arrangements. Seven o’clock tonight you’re
going to talk to the president and the board of directors and all
the vice presidents at Grumman.” It was like an hour from now.
He said, “I don’t want it written down. I want you to
tell them.”
So I said, “Okay.” I went in that conference room, and
their big senior vice president was a fellow named George [F.] Titterton.
George Titterton, and I’ll come back to him later, but George
Titterton was, I believe, the senior vice president at the time. I
told them what I thought, they didn’t know what the hell they
were doing; they didn’t have schedules; they didn’t have
procedures for anything; they didn’t have work orders; They
didn’t have a quality program. You know, I went through the
whole smash of why they were so far behind. They were years behind
in the development of the lunar module. I thought George Titterton
was going to have heart attack right there. I could see his eyes going
and going and I got worried about—but I laid it on the line.
Lew [J.] Evans, the president—[E. Clinton] Clint Towl the chairman
of the board, when I got through, Lew Evans come up there and says,
“I know exactly and I understand exactly what you’re telling
us.” He said, “I wish I could fix it.”
Clint Towl said, “Yeah, we’ve got a bunch of people here
that are really great, but we don’t have the quality system
or anything else that can make it even greater.” He said, “But
we get along. We build our airplanes.”
Well, I was sailor in World War II, and Grumman was supplying the
airplanes for the war, and my home town had the biggest General Motors
manufacturing plant in the country. It was the Linden [phonetic] Division
of Chevrolet, Pontiac, and whatever the other one was. When you bought
a car, if you had it made there, you could pay the workmen a couple
of fifty-dollar bills, and you're get four coats of paint instead
of one. You know, it was one of those operations. It was so big that
you could get anything done in there that you wanted as long as you
paid for it.
Well, Grumman couldn’t produce the airplanes for the war, and
they took over the General Motors plant and converted it to Eastern
Aircraft. All right. Now, there’s some connections here. George
Titterton was assigned as the contact to Eastern Aircraft, and Eastern
Aircraft was to build the TBM [Avenger, a torpedo bomber], the F-6F
[Hellcat], the F-4F [Wildcat], and whatever else the Navy needed,
okay. I had just graduated from high school and entered the Navy.
I was too young to go by myself, so my father had to sign a waiver
to let me get into the Navy. But the friends from home—I saw
them once and a while or wrote to them once in a while.
Then I met Mr. Walter Burke, who was senior vice president at McDonnell
when I first got there. All right. Then when I got know Walter Burke
a little better, I found out he was the chief engineer at this Eastern
Aircraft Corporation. Okay, so he knew George Titterton, who was the
interface. Then I got the whole story. Between my schoolmates at home
and the story from Walter Burke, Grumman couldn’t produce the
airplanes fast enough because you couldn’t stamp out parts.
You couldn’t mass produce parts. Each one was hand-made.
So Eastern Aircraft tried to mass-produce the parts like they do in
an automobile. They had to loft the airplanes and design them from
scratch so that they knew the size of all the parts. The drawings
from Grumman—no dimensions on most of them. The guy cut the
part to fit, you know, drill the holes. Okay.
Anyway, so Walter went through that at Eastern Aircraft, and they
built—oh, in order to loft it, they had to have dozens of people
to measure the parts and fit, and all the children, all my graduate
mates were hired by this Eastern Aircraft to do that job. So every
time I got a letter from some of my friends, they would tell me about
all this work they were doing to loft the airplanes. Well, the kids—I
call them kids, we were kids in those days—they did the job
and Eastern Aircraft pounded out 33,000 airplanes in three years.
That was a hell of a lot of airplanes.
If you remember, the four airplanes, or three airplanes, that went
in formation under the George Washington Bridge, they came from that
factory. The pilots came over and flew them off to Mitchell Field
in New York, where they were processed to go onto the carriers and
so forth. These guys decided to fly in formation under the George
Washington Bridge. I think all of them got court-martialed in some
way or other, but they went under the bridge in formation and came
out the other side and delivered the airplanes. But that’s the
story of the status of Grumman.
Now, all this time while Eastern Aircraft made 33,000 airplanes, Grumman
made less than 3,000. So you see the difference between a good production
operation and a cut-to-fit-and-paint-to-match operation. Anyway, that
is the background I had when he asked me to go to talk to these high
wheels from Grumman. So I knew the company better than most people,
knew because my classmates were the people who took that stuff and
made it work.
Anyway, after that, I went on home, went back to doing the job on
the Skylab. Well, one Friday—I’m going back to Marilyn
Bockting now—I got this call from Marilyn Bockting. I went around
in a big circle. Anyway, I got this call from Marilyn Bockting, and
I got down there at 4:30. I didn’t know what he wanted to talk
about. I thought maybe he wanted me to tell him what I had told the
people at Grumman, but not what he wanted at all. I sat there and
he told me. He told me that he was losing control of the command and
service module out at Downey because Eberhard Rees and his hundred
merry men were out there. They had gone into Downey to fix the problem,
okay. Bill Gray was out there with his JSC team, but now Eberhard
Rees, who was the director of Marshall, took his engineers and went
out there to oversee the program, because now they were through with
the Saturn V launch vehicle. They had a lot of men leftover and not
too much for them to do, right? So they decided they were going to
go out to Downey. So they were making changes. He said he couldn't
keep up with the changes they were making. They were spending money
like mad and couldn’t account for the dollars, and Bill Gray
was frustrated and couldn’t do anything either.
So he said, “I’m losing control of the CSM program, and
if we’re not careful, we’ll all be working for Marshall.”
Then he got on the lunar module. He said, “I heard what you
said about the lunar module.” He said, “We can’t
let Marshall get a foothold in the lunar module, because then they’ll
have the Saturn V, they’ll have the CSM, they’ll have
the lunar module. What’s there left for JSC to do?” Anyway,
it had him really worried. Then he said, “Right about now your
wife is getting a telegram transferring you to Grumman eight o’clock
Monday morning.”
I said, “Ye gods, I ought to be there, you know. Why am I down
here and you sent a telegram up there?” I said, “She reads
that thing, she’s going to have a conniption.”
Anyway, he said, “What are you going to do?”
I said, “Well, if you want me at Bethpage [New York, site of
Grumman plant] eight o’clock Monday morning, that’s where
I’ll be.”
Then he said, “But we have a manager up there. What do you want
me to do with him?”
I said, “If you can transfer me between now and eight o’clock
Monday morning, you sure as hell ought to be able to transfer him.
So I don’t want him there when I get there. You can’t
have two managers in a job at the same time.” So they transferred
the manager out to the West Coast with Eberhard Rees on a special
assignment.
So, Monday morning I appeared at Grumman. Well, I was there, I think.
Introduced myself around to everybody. Since I had made that talk,
I knew all the big wheels at Grumman anyway. So I took over the office.
I think I was there three or four days. NASA had just had a big acceptance
review of lunar module number two. After I was there about three or
four days, the secretary said, “There’s a whole bunch
of NASAs here that want to talk to you.”
Well, the first thing that came to my mind was [they would be asking],
how do I get out of this chicken outfit? I sat there for a few minutes,
and I said, “Well, my answer’s going to be, you don’t.
Not until I’m ready for you to go.”
But when I had them come in and sit down, that’s not what they
were there to tell me. They were there to tell me that LM 2 was not
flight-worthy. And I took off. I said, “You’re responsible
for this LM. You’re the guys that are here, supposed to make
sure that everything goes right. Now you’re sitting here and
telling me it’s not flight-worthy?”
They said, “That’s right. We won’t consider it flight-worthy.”
I said, “But NASA’s already accepted it. It’s sitting
over there waiting to be shipped.”
“We want you to call George Low and tell him it’s not
flight-worthy.”
So I reached out and picked up—after a good bit of argument,
I finally reach out and picked up the telephone. If all of these guys
are saying this, you know, there must be something to it, and I wasn’t
there long enough to know. So I called him, and I explained to him
about everybody in my office here, they’re telling me this vehicle
is not flight-worthy. I said, “I don’t know what to do
except to tell you.”
He said, “I don’t know what to do either.” He said,
“Why don’t you go and conduct your own inspection? Then
you call me back and tell me.”
So I took two days and I took all of these guys down there and said,
“Now, show me what you’re talking about.” Sure enough,
it was a mess, you know, wires going over sharp edges that won’t
last a launch, and the workmanship was terrible. Every place we went,
it showed me fluid lines not tied down right, wire harnesses not tied
down right. Finally after two days—oh, then we got into the
checkout. They started telling me about the test history. Well, Grumman
was manufacturing when they had parts. If they didn’t have parts,
then they did testing. Then when they got some more parts, they did
some manufacturing. When they didn’t have parts, they did some
testing. So you never tested a whole system. In fact, they tested
some systems and then found out they got parts that had to go behind
and, instead of taking those systems apart, put those parts in. It
was really a slipshod opportunity.
I finally called George Low back, and I said, “I agree with
them.” I said, “Why don’t you just tell me to scrap
it. I’ll have the QC [quality control] guys write a MRR [material
review report] and we’ll designate it as scrap.”
He said, “No, no, no, we can’t. We’ll make a big
problem here and we’ll get more Marshalls.” He said, “I’ll
tell you—let me think about it.”
He called me back a couple of days later, and he said, “I think
I've got the solution.” He said, “What we’ll do
is we’ll ship it to JSC. I always wanted to do a drop test.”
This had honeycomb for shock absorbers and stuff, those big boots
down at the bottom, and so forth. He said, “We’ll ship
it to Houston. I always wanted to do a drop test.” He said,
“We’ll drop it and we’ll test the landing gear strength
and all of this kind of stuff, see what else goes wrong. Then we’ll
clean it up a little bit and we’ll ship it to Japan for the
World’s Fair. They want a display from Apollo on the World’s
Fair in Tokyo.” He said, “We’ll ship it to Tokyo
and that’ll get it out of the system.”
I said, “You’re right. That’ll get it out of the
system,” and I said, “I’ll be happy with that.”
So that’s what we did with LM 2. So the team there was satisfied
that nobody was going to get hurt flying that thing.
I guess I was there another week or so, and Lew [Lewis R.] Fisher—I
guess you’ve talked to Lew Fisher already.
Butler:
No, we haven’t yet.
Hobokan:
Lew Fisher was my deputy for engineering up there. Tony [Anthony L.]
Liccardi was the deputy for test operations for me. Two great guys.
So I was there about a week or ten days when Lew Fisher came in, and
he said, “A big problem.”
I said, “What now?” Grumman had mounted the docking tunnel
on the roof skin of LM 3, but they had it indexed 180 degrees from
where it was supposed to be. So I said, “Come down. I want to
find out how this happened.” Well, the workmen couldn’t
interpret the drawing. I said, “Well, where’s the work
order that tells you how to index this thing?” No work order.
I said, “Well, where’s the inspector?”
And the inspector says, “Hey, if they can’t interpret
it, I can’t interpret it.”
So I got Lew back in the office and we said, “What’s going
on here?”
He said, “Well, the Navy is the cognizant plant.”
I said, “Oh, déjà vu all over again, just like
the Leo Durocher [phonetic] said.”
He said, “The Navy’s got cognizance of this plant.”
And that was that. I had the contracting officer right there, right
next to my office, so I walked out the door and into his office and
I said, “I want everybody on that NASA payroll whose salaries
are being paid for by NASA transferred to my office for the day-to-day
operations right now.” Well, he was delighted to do that. He
didn’t like the Navy guys anyway. The Navy guy, I tried to talk
to him, and strangely enough—when I talked to him the last time,
he said, “Look, I’m retiring in a month or so, and I got
a good job lined up with Grumman. I don’t want anybody making
waves while I’m on my last month here. I got it knocked, and
don’t screw it up for me.”
So when I got to Frank Battersby [phonetic]—he's dead now, but
he was my contracting officer, and Frank didn’t like the Navy
guys anyway, so when I said, “Transfer all of those people to
me,” he did it. He jumped right on it, and the next morning
I had all these Navy guys now that were NASA guys. I had a QA [quality
assurance] manager named Harry Briggs. Harry Briggs, I think, passed
away two or three years ago, maybe a little more. But I sat down with
Harry and I said, “Look. Now you got this whole staff. You didn’t
have this responsibility before, but now you got this whole responsibility.
You got all these inspectors. You assign them their jobs. You got
complete control of it and I want a quality job.”
He said, “How about the Grumman QC?”
Well, the Grumman QC guy’s name was Joe Kingfield. So I said,
“Get Joe and you and him come into my office.”
Well, when I talked to Joe Kingfield, Joe Kingfield said he reported
to the project manager, which was Joe [Joseph G.] Gavin [Jr.], Vice
President Joe Gavin, and he [Kingfield] said, “If I raise a
ruckus, he’ll fire me.”
I said, “You’re not going to report to Joe Gavin. You
come with me.”
So Harry and Kingfield and I went over and we walked into Lew Evans’
office and I said, “Lew, tell this guy he works for you and
that Joe Gavin can’t fire him, that you’re the only person
that could fire him, and you’re not going to fire him without
my permission.” I said, “You tell him that right now.”
So we all sat down and had a cup of coffee with Lew Evans, and Lew
Evans said, “That’s the way it is, Joe. Now you work with
the resident office, the RASPO. You work with the QA people and you
do the bang-up job that they want done.”
So, anyway, I felt pretty good, and I went home and had a couple of
good cocktails. Next morning I came to work, the phones were ringing
everywhere, and the secretary was jumping up and down. She said, “I’m
glad you’re here. George Low’s been calling and calling
and calling for hours.” He must have started calling at five
o’clock.
I picked up the phone, and he said, “What did you do?”
Here it comes again.
“What did I do?”
He said, “Yes, why did you shut the plant down?”
I said, “I didn’t shut the plant down.”
He said, “Well, the whole plant’s shutting down. Everybody’s
calling down here and saying you've got the whole plant shut down.”
So I said, “I’ll find out and I’ll call you back.”
So I went out and I got Harry Briggs. I said, “Harry, what’s
going on?”
He said, “Those new inspectors have everything shut down.”
I said, “What do you mean by that?”
He said, “They must have had a bushel basket full of stop work
orders, and the stop work orders says," you know it’s a
federal offense if you work on this job while this tag is hung. They
must have had a bushel basket full of those tags and they had on every
job that they didn’t agree with, which was, you know, ninety
percent of the work.
I said, “Get Joe Kingfield and then we’re going down.
We’re going to talk to the inspectors.”
So he got Joe Kingfield, and the three of us went down. The first
tag I saw there, I stopped and asked the inspector why the tag was
there. Well, no drawings, no work order. Well, that’s a good
reason. Go to the next one. No drawings, no work order. Go to someplace
else, he’s got a red-line drawing all marked up. After I got
through with all of this, I said, “These guys are right. You
know, they should be handing those tags.”
So I got up there and I called George Low back, and I said, “George,
these guys are doing their job. They’re right, and it’s
just a shame that, you know, it all happened at once because the whole
plant is shut down.”
He said, “Well, see what you can do about fixing it as fast
as possible.” The LM was already years behind schedule at this
point, and I know he’s tearing his hair out.
So I went to the planning office. The guy, head of production planning
and scheduling was a guy named Bill Going [phonetic], an ex-basketball
player. I said, “Look, your corporate policy says you take a
drawing. It’s a released drawing. It goes through production
planning. You guys write the route cards, the work orders. QC then
takes those things and stamps them that they’re ready to go
to work. They get the parts and all this kind of stuff. Then you do
the work and you stamp it off. That’s the way your policy is,
and that’s what you’re going to do.”
And he said, “Okay.”
But three days later, nothing happens. So I go to see him again, and
he said, “Andy, we can’t do it. We just don’t know
how. We’ve never had to do it before and we don’t know
how.”
I said, “Go hire a company and get it in here, and then while
they’re doing it, you can get your people OJT and then you can
get the company back out of here.”
Well, about three days later I’m still hearing from George Low
every day and I keep telling him, “Give me some time. Give me
some time. I’ll fix it. I’ll fix it.”
And suddenly they’re in my office. One Friday afternoon walks
in Lew Evans, the president of the company, and he sat down and he
said, “If you want these people trained to do the job the way
it should be done, then you’re going to have to train them yourself.”
I drank that in and I said, “Oh, my, you know, I can’t
train all these people. Just beyond the scope of what I’m going
to do.”
So we talked for a while and he said, “I tried to find a company
to do this. I talked to other companies to see if they could spare
some people. I haven’t been able to do anything. But my back
is against the wall, and I've got to get this production going.”
So I thought about it for a while, and then I walked out to my secretary
and I said, “Get me Walter Burke on the telephone from McDonnell."
It was now McDonnell Astronautics in St. Louis. I said, “Get
him on the phone. Tell him it’s important that I talk to him.”
So she came back in. I had a speaker phone and I wanted Lew to hear
the conversation, but I told him, "Don’t say anything.
Just listen." And I punched the button up.
After pleasantries and so forth, I said, “Walter, I’m
in trouble.”
He said, “What are you in trouble about?” So I told him
about the situation.” He said, “What do you expect me
to do?”
I said, “I would like for you to train the Grummans in your
position planning operation so that we could use that here.”
He never cusses. He’s a Lutheran minister. He never cusses,
but you sure know when he’s cussing you out with some nice words.
He says, “They’re our biggest competitor. We’re
not going to do it,” and a whole bunch of other stuff.
I said, “Walter, I know you can’t do it on your own. What
I want you to do is go up there and tell Mr. Mac [James S. McDonnell,
Jr.] I’m in trouble. I’m trying to head off a problem
in orbit or on the surface of the Moon or on the way back to the Earth.
Tell him I’m in trouble. I need his help.”
He said, “I don’t like it, but I’ll do it for you.”
Well, Lew Evans and I sat there for another half hour or two or more,
and the secretary walked in and said, “Walter Burke’s
on the phone.”
So I punched the speaker phone button, and I said, “Hello, Walter."
And he says, “You got to be the luckiest guy on in this whole
world.”
I said, “What do you mean by that?”
He said, “Mr. Mac told me that that program is so important
to this country that if you’ve got a problem, I’ve got
to fix it.”
So I said, “Thank you."
And he said, “When do you want to do this?” Now, this
is Friday afternoon, remember, about three o’clock. He said,
“What do you want done?”
I said, “I want you to train these Grummans in your position
planning scheme so that they can do it here on this lunar module program.”
He said, “That’s a big order."
And I said, “Sure.”
He said, “When do you want to start this?”
I said, “Eight o’clock Monday morning."
And he said, “You’re not giving me much time.”
I said, “Walter, I don’t have much time."
And he said, “Okay, eight o’clock Monday morning. How
many people do I plan for?”
Right off the top of my head, I said, “Fifty."
And he said, “All right, I’m going to expect fifty people
eight o’clock Monday morning in St. Louis. You make sure you
get clearances for all those people here, and we’ll be ready
for you at eight o’clock Monday morning.”
Now, Lew’s sitting over here and he’s dazed, and I said,
“Lew, Lew, Lew, can you get this done?"
And he said, “I think I can. I’ll get on it right now.”
And they packed up fifty people, got them to St. Louis, and I put
my TRs in my pocket, I figured my passport’s there [in St. Louis]
and if I have to leave the country, at least I can go get my passport.
So, anyway, I went over there and I came into the planning room for
McDonnell. It’s like a big auditorium. I’d say it’s
twenty times, thirty, forty times this space. Had a hundred desks
in it. Bill [William] Dubusker, their manufacturing manager, always
maintained no papers on the desks when you leave. He kept the greatest
planning department you every saw. No paper on any desk ever when
they’re not working. Anyway, all these desks empty, and standing
at each desk were two chairs, and a McDonnell guy was at each of the
desks. When the Grummans started coming in, they asked about QC, whether
you’re production planner, you’re a production scheduler,
you’re an estimator, whatever, and they paired them off. Every
McDonnell vice president was there, and it was tremendous thing.
I took one look at that and I said, “I can’t do any good
here,” so I went over and said, “So long” to Walter.
I said, “I’m going back to New York. How long are you
going to keep these guys?”
He said, “I have it planned for two weeks.”
I said, “Okay, I’ll be back in two weeks.”
So I went back to New York, and the plant is quiet. Nothing is going
on on the lunar module program. All these damned—every time
you walked down there, all you see is these damned tags hanging on
everything, see the NASA inspector standing around, nothing being
done.
When the two weeks was over, on a Thursday night I flew back to St.
Louis and I called Walter, and he said, “Everything went great.
I think they really are having second thoughts about the way they’re
working and they look like they’re going to work the way we’re
training them to work.”
So I got my wife and I said, “Look, throw a party tomorrow night.
We've got to throw a big party for the Grummans and the McDonnells
and finish this thing properly.” So she threw a big party that
night. We had a room half as big as the planning room. So we had a
big party there. She’d cooked four or five turkeys and hams
and stuff. The neighbors were cooking for her.
Anyway, we threw a big party, and everybody headed back toward Bethpage
on that Saturday and Sunday. There were so many of them, you couldn’t
get all out on Saturday. You had to split—some of them flew
Sunday and Saturday.
Anyway, when we got back to Bethpage, it took about three days and
then you see a sea of change. Man, every place that work was being
done was called a workstation. They had planning books. This is electrical.
This is fluid lines. This is structure. This is whatever else, you
know, and installations and so forth. Every place you looked, they
had these books. Wasn’t anything in them, but they had the books
there and they had the workstations defined, and they were defining
the work teams.
The next day, you see two or three pieces of paper coming down, going
into these books. They weren’t labeled like they used to be,
"LM 3." They were for "LM 3 and sub [subsequent],"
meaning it applied to all of them, so that now instead of working
one vehicle, you could work four or five vehicles at the same time
because you issued the same work order for all of them and then you
put the extra copies for the ones you’re going to start later
on. You’re already doing those books.
Well, it took them forty-odd months to build a LM 2, and it took thirty-two
months to build LM 3, and it took twenty-six months to build the rest
of them because of that good planning. You know, everybody knew what
work was going to be done. The people knew when the parts were going
to be there. We had the best schedules in the world. You just wouldn’t
believe what happened.
Unfortunately, Mr. Burke’s biggest worry came true: the Grummans
applied the system to the F-14 program. When they applied it to the
F-14 program, Republic Aircraft was a subcontractor. They forced them
to use the same system, so there went McDonnell’s advantage
on being able to properly estimate the cost and time and everything
to make it work. But it went that way.
The big problem then was when we shifted to testing. Grumman didn’t
have a test team. So we insisted that we have a test team. They put
a guy, I think his name was Standefer [phonetic], in charge of the
testing. He was a good manager. He picked the best people he could
find to do the test work. So we started writing the test procedures.
All this came under Tony Liccardi. Now, he was the honcho on all of
this for me.
I called George Low and I said, “I need to rewrite all of the
test documentation. That’s going to be a lot of money.”
He said, “Well, don’t do it.”
I said, “But we've got to do it, and we’ve got to rewrite
the whole smash. It’s going to take us four months or something
to get it done. I’m going to run your bill up getting this done.”
He said, “Well, I don’t think you ought to do it.”
I said, “Look, you got a guy down here named Don [Donald D.]
Arabian." Don Arabian was the head of POO. We were old friends,
and I think it was appropriate that he was the head of POO. Anyway,
I said, “Send him up here, and I’ll walk him through it.”
That was the Program Operations Office, and they were responsible
for the MER [Mission Evaluation Room] and so forth. His people knew
something about testing, and Don knew a lot about testing. I said,
“Send him up here. If I can’t convince him that we've
got to do this, then I’ll tell you.”
So Don came up and spent three days with me, going over all of this
stuff and how bad it was and so forth. He finally said, “I agree
with you. If you don’t rewrite these procedures, we’re
never going to be able to have confidence in a lunar module."
So he went home, and I got a phone call a day or two later from George
Low. He said, “Go ahead and do it.” So we rewrote everything.
Tony Liccardi was tearing his hair out because there were so many
documents to take care of, and we had other problems cropping up.
Anyway, the test procedures were rewritten. We had a team and we developed
a process where manufacturing owned the vehicle, and when it was manufactured
up to the configuration that the test people wanted it, then the test
people owned the vehicle and manufacturing was out of the loop. Now,
the test people could call in manufacturing people to do what they
needed to do, but manufacturing wasn’t able to go in there and
screw up the tests. The test guys took care of all that themselves.
And it worked beautifully.
We didn’t have a very good program manager. Joe Gavin was at
that time considered to be the program manager. Tom [Thomas J.] Kelly
was considered to be the program manager, and there was a guy named
[Robert S.] Mullaney or something that, who was the real program manager.
When I got there, I couldn’t find Mullaney, and I had been beating
Lew Evans on the head to get a program manager in there that would
meet with the new concept of what we were doing, the new planning
and scheduling, the new testing, and so forth. He said, “Well,
OAO," the Orbiting Astronomical [Observatory] thing, "the
OAO office is closing down. There are some good people over there,
and I’ll go shop around.”
Well, he found “Doc” Tripp, Ralph [H.] Tripp. Ralph Tripp
was a quiet guy. He had a degree in physics, I believe, and he was
instrumentation oriented, so testing was something he understood.
When Lew Evans offered him the job, he wasn’t going to touch
it with a ten-foot pole. He knew that there was trouble there.
Anyway, finally, after I talked to him, Lew talked to him four or
five times, the chairman of the board took him out to dinner once
or twice, and finally they convinced him to take the job. So he became
the new manager. He helped us with the testing, get the testing organized.
Since we had, now working on a bunch of vehicles, we had to get more
ACEs, more ACE equipment, so he was instrumental in getting us another
set of ACE equipment, and we had the cables going down the steps.
We couldn’t even install it properly, but he got all that stuff
going for us, and we were now checking out the vehicles properly and
so forth.
Suddenly one day a window broke. I got this call from Harry Briggs
that said, “A window just broke on LM 4.”
I said, “Who hit it?”
“Nobody hit it. We were doing a pressure test on a crew cabin
and the window broke.”
When I checked, the window broke at 4.8 psi, and the cabin pressure’s
5.0 psi. How did that window break?
So we called Corning Glass. This is a special chem-core [phonetic]
process. I don’t know if you ever heard of it, but you take
the glass and you get it good and hot. Then you clench it, and the
outer pieces shrink, but the inner one is still solidifying, but outer
ones are shrinking faster than the inner ones, and you can bend that
glass. These windows are big. The way you test them is you bend them
over a one-inch roller, one of the tests that you do on a window.
Anyway, the window broke, and it broke at a low pressure. It was scary.
So Corning couldn’t find out why the window broke. Doggone,
a month later, another window goes on LM 5, 4.5 psi. These windows
are made out of the same stuff like your car. They’re made to
shatter into little pieces that don’t have shards that could
cut an astronaut’s suit, okay. It goes like sugar. If you break
the window, you got a pile of sugar that’s not sharp-edged,
okay.
Anyway, the second window broke, and we never could figure out why.
So I called the quality people together and I said, “I’m
issuing orders to you now. I want every window to have an inspection
before every operation and an inspection after every operation, and
I want you to look at the slightest difference, and anything you see,
I want to know immediately.”
Well, I think four months or so went by, and one day the secretary
walked in and says, “There’s an inspector on the line
and wants to talk to you.”
He said to me, “I’m down here at the thermal chamber,
and we just took a window out of the thermal chamber and I see something
in here now that I didn’t see on this window before we put it
in.”
I said, “I’ll be right down. You put your stop-work tag
on it. Don’t let anybody touch it.”
So I came down there, and he said, “It’s right here in
the glass.” Well, I couldn’t see anything. He said, “Here,
take my loupe,” and I go down there with that little loupe,
and I couldn’t see anything. He said, “Look right here.”
He had a flashlight. [I saw what looked] just like a diamond in the
glass.
So now we had something to go on at least. We called Corning in, and
I had that impounded. You know what bonding is; nobody can touch it.
It’s just considered government equipment and nobody can touch
it without your inspector’s permission. So, anyway, they came
in and they looked at it, and they said, “Sure enough, looks
like a stress riser in there.” So they got another window. They
put it through the same thermal test, and they examined that piece,
and, sure enough, there was what looked like a stress riser in there.
So they took the second window and they pressurized it and it broke
at 4.5 or 4.6 psid.
Anyway, now we thought we had the real cause, but when they analyzed
this thing, it was the anti-fogging ribbon on the window. You know
the anti-fogging ribbon, you put it on the window, heats the window
so the window doesn’t fog, and where it comes out, it gets connected
to the wires from the electrical system. Well, when they glued the
wires to the window, right where they put the electrical connect wires
coming out, they used a thing called Hysol [phonetic] as the adhesive.
The Hysol was selected because it was strong and it was good. Fact
of the matter, it was too damn strong. The window had a coefficient
of expansion, you know. When it gets hot and cold, the coefficient
of expansion of this Hysol was zero, but the bonding to the window
was so great that when the window moved there, it just tore the glass.
So this one inspector—I wish I knew his name—he should
have gotten a [Silver] Snoopy [Award] for his work, and I didn’t
do it and I’m sorry to this day, but how he found that little
diamond in there, he must have been examining that thing with a fine-toothed
comb, because it was so small I couldn’t even find it until
he pointed it out with his flashlight. But it solved the window problem
and we didn’t have any more window problems.
Butler:
Before we go any further, actually, if we could just pause to change
our tape out real quick. [Tape change.]
Hobokan:
...we got to building several at a time, and he was putting on—we
had called what we called spacecraft managers. Al Geweed [phonetic],
you probably heard of his name in the past, worked for me, and he
was the spacecraft manager for LM 5, Eagle, okay. We had a manager
for LM 4 and LM 6 and 7. We rotated these guys. As one vehicle left,
we put them on another vehicle.
George Titterton put a man named Harrington on LM 6, but I’m
jumping ahead of myself. Just a minute. We had solved the window problem
and the test problem, and we got down to where Apollo 8 was going
around the Moon. Apollo 8 went around the Moon because there wasn’t
any lunar module, okay. Now, right after that, we were going to deliver
LM 3, in the first part of 1969. We had to do this thing before 1970,
if you remember.
So we came up to Christmas on 19[6]8, and I was ready to deliver LM
3 to KSC. There were about five things that were undone on the LM
3, late changes because we had no parts. We couldn’t do them,
so I said, “We’ll ship it to the Cape. I’ll send
the people. We’ll get the parts. We’ll go down there and
do it after it gets to the Cape.”
A couple of people at JSC said, “No, we want those changes made,
and we want them made as fast as possible.”
Well, Grumman had planned to work over the Christmas holidays, between
Christmas and New Year’s to finish up, package the vehicle,
and ship it to the Cape. I called George Low and said that was their
plan. From General Bolender comes this comment that we need all those
changes made. I said, “General, I just got the word that if
you want those changes made, Grumman is going to take the whole time
off until the parts arrive, and nothing’s going to get done.”
So they insisted that they include the changes. Sure enough, within
two hours, there was a letter telling everybody to go home from noon
on Christmas Eve till the second of January. So I went to the contracting
office, and I said, “Look, this is not a scheduled holiday.
Sue the company for the money. We won’t pay for these holidays.”
So we sued Grumman. Lew Evans came over and said, “That’s
two and a half million dollars of our profits you’re going to
take.”
I said, “I didn’t tell you to put those people off. You
did it, not me. The lawsuit stays.”
Frank Batterby [phonetic] was working with the federal government
in getting this done. Then something else came up, and we got some
more money involved, and I said, “Sue them again. They’re
either going to stick to their money plan and what kind of holidays
they have, or they'd better tell us about it in advance. We just can’t
afford this money going for no production.”
Anyway, we sued them again. Now things are getting strained between
me and Lew Evans there because of this.
Right after the first of the year, we had delivered LM 3. In January
we got the parts and delivered LM 3. Suddenly my secretary came in
one morning and said, “Wernher von Braun is here to see you.”
I said, “Send him in.”
Wernher came in and he says, “Where can I find George Low?”
I said, “George Low? I didn’t even know George Low was
coming up here today.”
He said, “Yes, he called me on Friday and we were to meet here.”
So I said, “If he told you he was going to meet you here, he’ll
be here. Why don’t you sit down.”
He said, “I’ll take my man and we’ll tour the plant.”
He had a representative on my staff, a guy named Franklin, and so
he got out and got Franklin, and they were going to take a tour of
the plant.
It wasn’t long later that George Low came in, and George Low
said, “I want to take a tour of the plant.” So I took
him on a tour of the plant, and he said, “I don’t want
you listening to what I’m talking to these guys about. I don’t
want them to be concerned about you doing anything to them if what
they tell me that you don’t like, okay.”
So I said, “That’s fine. I’ll stay out of earshot.”
So I took him to wherever he wanted to go. He wanted to talk to some
propulsion people. He wanted to talk to structures peoples. So I just
walked off and let him talk to them. I got the word from him later
that he was asking them what was their personal opinion of the lunar
modules. They built them. Did they believe in them or didn’t
they believe in them? What was their concerns? After doing this for
about two hours, he talked to quite a few people, and he said, “Okay,
I’m ready to go back to your office.”
We go back to my office. He said, “Let me see your schedules.”
Well, as I said before, we had a whole new scheduling system. We had
the best schedules in the world, and I had them all laid out for every
LM that we were ever going to build. He wanted to see the schedules.
He said, “How much confidence to you have in them?”
I said, “Right now, I can tell you within three days every one
of those deliveries is going to take place within three days of that
date.”
He said, “How long is the Cape going to take to process the
LM?”
I said, “Well, they keep saying three months, but they’ve
never seen one.”
He said, “That’s right. If they have a lump, we’d
better say four months processing at the Cape.”
Then Wernher von Braun came in, and we all sat there going over the
schedules, this, that, and the other thing, LM 3, LM 4, LM 5, LM 6,
LM 7, and so we started out with the January 1st, 1970 and started
working back. And there was LM 6 sitting there for, I think it was
September or October of ’69. We discussed LM 6, and Wernher
was saying, “That’s too late. That’s too late. That’s
too late.” When you put the four months of scheduling at KSC
in there, you were going to launch that one after 1970, after January
1st. So we all agreed that LM 6 was too tight and too close and we’d
never make it.
So then we went to LM 5. LM 5 was delivered four months earlier, back
four months up. We looked at LM 5, and that had plenty of slack. If
you took the four months for the Cape and then a bumper here or there
with rockets, you know, you had a little time, a little lead time.
Then we went to LM 4. Well, LM 3 was already off, so LM 4 was in March
or April, and it had lots of time. Wernher von Braun wanted to go
with LM 4. So he was arguing LM 4 was going to be the first lunar
landing, and George Low didn’t want that. He wanted LM 5 to
be the first lunar landing, and he had reasons of his own, like the
damned LM 4 was a little heavier than it should have been.
Anyway, Wernher was getting upset and he said, “Do JSC’s—“
Oh, George Low mentioned a few things about backup. He wanted to have
LM 4 as a backup to LM 3. This vehicle had never been manned in orbit
at this point. Now, it’s after January 1st, 1969. Not one of
these vehicles had ever flown man, and we had to do it by January
1st of 1970. So that’s your back against the wall and you’re
between a rock and a hard place besides.
So he said, “I want LM 4 to be able to go into Earth orbit if
Jim [James A.] McDivitt’s flight had a problem.”
Wernher came unglued. He said, “You JSCs want backup on backup
on backup. Sometime you have to make your mind and go.”
Well, that was pretty strong language, but George Low wasn’t
giving in that easy. Finally he said, “I’ll tell you what,
Wernher. We’ll go with LM 5 internally, and we’ll tell
the world we’re going with LM 6. Between the three of us in
this office, we’re planning to go with LM 5, but we’re
going to go and tell everybody else we’re going with LM 6. Andy,
call Lew Evans. We’re going over to see him.”
So we went over to Lew Evans’ office, and George Low broke the
news that we’re going to make the first lunar landing with LM
6. So Lew called George Titterton. George Titterton then assigned
Harrington to that vehicle. Harrington was a friend of his. So he
assigned Harrington to LM 6. But LM 5 we were working on internally
to make that first landing.
Anyway, when you looked at the open items on the LM, there were thousands
of open items. You know, failures here, failures there, failures in
that subcontractor, all kind of failures all over the place, and all
of these have to be closed out by the FRR. So here’s Grumman
working to close them out for LM 6. Well, I had to work to close them
out for LM 5 without telling the Grummans that’s what I’m
going.
So we got with Carroll Bolender, General Bolender, and said, “We’ll
put some incentives on closing these out.” So we had a quarter
of a million bucks, I think, that we could put as an incentive there
for Grumman to close them out by LM 5, so that they’re closed
by LM 6.
But then JSC was the big problem. JSC never had much to do with the
lunar module. I didn’t know anybody from JSC who ever worked
on a lunar module other than General Bolender. We had so many items,
that when it came to sending them to JSC to close them out, the JSC
guys wouldn’t close them out because they didn’t know
enough about the LM to be able to say, “Yes, I can agree with
this,” okay. So it got to be pretty touch-and-go there for a
week or so.
Finally I called George Low and I said, “We've got to do something
about this. I'm JSC. Why don’t you give responsibility to me.
If your damned engineer won’t sign it off, then I’ll review
it and if I agree with it, I’ll sign it off.”
So he said, “Okay."
I said, “I’m going to need some men.” So he sent
me a young fellow named Dave Anderson from General Electric, and he
sent me about eighteen General Electric engineers. We put in a fax
machine and we put in extra telephones for these guys. These guys
were to work with the Grummans to close out the paperwork and then
ship it to JSC to have it signed. If they didn’t get it signed
at JSC, then it came back and me or some of my engineers would review
it. If we thought it right to sign it off, we’d sign it off.
Well, we put that into effect, and the guys at JSC suddenly realized
that, you know, they’re not seeing anything now. Before they
at least saw the failures. Now they’re not seeing anything because
when they got the piece of paperwork and they didn’t act on
it right now, the piece of paperwork disappeared out of the system
because it came back to us, and we worked it with the Grummans up
there. Anyway, we started to clean up the backlog, and with the incentives
we got the whole job done pretty well. But Dave Anderson was a key
person in getting all of that done. Those GEs were at that time working
at JSC also, so he had a direct line to his own people down at JSC
on how the wind was blowing on this and that, and he could get those
guys down there to pave the way for this piece of paper coming down
so it’d be signed when it got there. He had his people telling
them, “Look, if you don’t sign these off, you’re
out of the loop. Somebody else is doing it. You’re not going
to know how it really wound up.”
So with that good scheme going, we got the JSCs doing more of it,
and I didn’t have to review a heck of a lot of them after them.
But old Titterton was pushing LM 6 now, not LM 5, and he had a management
scheme you won’t believe. He carried hundred-dollar bills in
his pocket. If he wanted something done on schedule, he used to bet
the foreman a hundred dollars that they can’t do that job and
get it done by this day, okay. Everything else stopped, but the foreman
got that hundred dollars. That was his management technique. It didn’t
move everything forward. It only moved one item, and, in fact, it
moved stuff back.
So, anyway, we got the LM 5. George Low said, “Keep the weight
out.”
I said, “If you can keep the changes down, I can keep the weight
out.”
He said, “I’ll keep the changes out.” So it stayed
a nice lightweight vehicle that it was planned, except that when we
got it to move to ship it to the Cape, on the overhead was a hook
to lift it. The hook has a pin to lock the hook closed, okay. Now,
the pin is held by a piece of steel cable that’s welded to the
top of the hook, except none of us ever looked at that weld.
This one day we were going to move LM 5, that pin came out of there.
The docking tunnel was right on the top, okay. The ascent engine is
right down the center, and under that is the descent engine. Luckily,
the engines weren’t in there. That pin came out, went right
through the hatch down through both engine covers. So now we had to
patch the engine covers and do an inspection of the whole damned hoist
system there.
We had the doors open for, I guess it was LM 4 for Apollo 10, to move
it out to the truck to take it to the airplane for delivery. A damned
squirrel ran into the white room. [Laughter] The squirrel was running
around all these LMs and so forth, and I didn’t know about it
until somebody came running to my office that the guard just shot
a squirrel in the white room. The guard shot a squirrel in the white
room? Where’s the bullet? Nobody knew. Where’s the squirrel?
They threw it out in the trash, and the trash has gone to the dump.
"Get me security."
We had to send a guard to find out where that truck dumped it and
find that squirrel and see if that bullet was in the squirrel. This
bullet, it was .38-caliber, it’d go right through that damned
squirrel. We all knew that, but you had to make sure. Then we found
a place where it hit the concrete wall but didn’t penetrate
the concrete wall. It went somewhere. So now we’re out there
with all kinds of projecting devices trying to find the trajectory
of this bullet. We never did find it. Someplace in a LM or in the
white room was the bullet that he shot at that squirrel, but we never
did find it. That was an interesting anecdote. But we spent two days
trying to sort that one out, and we never did find any trace of that
bullet.
We had another where somebody left a crowbar in one of the LMs. We
tilted them to clean them, and somebody had a crowbar that they were
doing something with and left it on top. When they tilted it, it came
crashing to the floor off the LM, and now we had to go down there
and do all this trajectory work again to see if it could have hit
a tank or whatnot. No, it didn’t hit a tank. But all of that
stuff scares the hell of you that you might have damage that you don’t
know about and so forth.
But the interesting thing about the Apollo Program was, it went off
without a hitch. When they put LM 4 in the vicinity—Tom [Thomas
P.] Stafford and Gene [Eugene A.] Cernan and, I don’t who was—
Butler:
John [W.] Young? Up in the command—
Hobokan:
Yes, up in the command module. I made the pitch for Apollo 10 reunion
down here. I did the talk on Apollo 10. I told them a lot of the things
that I’m telling you now. But when that vehicle went down, it
was too heavy to land, so it went part way down, and while they were
down there, Tom Stafford threw a switch. Now, I don’t know if
you knew about the AGS in the lunar module. The lags, the lunar module
had PINGS and AGS. PINGS was the Primary Inertial Guidance System,
and AGS is an Abort Guidance System. There is a switch that will allow
you to switch between the two.
When the PINGS is being used, the data is recorded in the AGS, so
that the AGS has access to that data. In other words, when you leave
the command and service module to go to the surface of the Moon, both
systems are plotting the trajectory and knowing where the LM is at
any given time. Tom Stafford threw the switch from PINGS to AGS. When
you throw the switch from PINGS to AGS, that vehicle’s going
back to the command and service module. That says, “I’m
in serious trouble, and I’m going home,” okay.
So here they are down around the surface of the Moon, and he threw
that switch and that LM turned around and started back, and he had
to throw the switch again and put it back on PINGS, and it stopped
that operation, and he made a big cuss word. I thought he said, “Son
of a bitch.” So they never would say that what he said until
the anniversary the other night. He said, “Yes, I said that.”
[Laughter]
Gene Cernan was saying, “He held me, kept me quiet all these
years, but he promised after thirty years, he’d tell me what
he said.
And he said, "I said it."
After all these successes of the lunar module, I got another phone
call, and it was from some people assigned to the space shuttle. They
said, “Andy, we have a bunch of drawings here for tooling, that
we don’t understand tooling. Would you review them for us?”
So I said, “Okay, I’ll review them. Just send them up
to me.”
So they sent them up to me, and I looked at these drawings. Everyone
was for 200-plus man hours. The Orbiter’s big, you know, so
these are big tools. Well, when I looked at them, every one is designed
in a different way. One is using round tubing. One is using square
tubing. One is using big tubing. One is using small tubing. The analysis,
I spent today and yesterday over here in Building 220 watching the
guys align the X-38, okay. Just breathing on the tooling, you can
see the tooling move, okay. Now, if you’re going to build big
tooling, you at least ought to have the same lattice work so you can
analyze one piece of lattice work and not go and analyze a different
piece of lattice work for every one of your damned tools, where the
coefficient of expansion and contraction is different.
So when I saw this stuff, I said, “Look, I’ll come down
to Houston. Why don’t you call those Rockwell guys in and call
their tooling manager in and let me talk to them.”
So I got to Houston. The guy’s name was McCarty [phonetic],
and Joe [Joseph W.] Cuzzupoli came. The tooling guy worked for Joe
Cuzzupoli. I said, “How come we got all these different lattice
works on the tools? Why aren't we using a common lattice work?”
McCarthy said something, “Do you design tooling?”
I said, “No, I don’t design tooling, but I know enough
about it to know that if I were going to do it, I’d do it with
the same damned lattice work on all of them, so an analysis would
be easy to do for the whole smash. Besides, these tools are so big.
Why aren’t they modular? You know, why don’t you make
modules that you can analyze and just stack these modules, how many
you want, use them for wing, the fuselage, the tail.”
Anyway, the tooling manager said something, and Joe Cuzzupoli said,
“Meeting’s over.”
So I got up and I flew back to Bethpage. Well, about a month later,
I got this phone call from Houston again that said, “Joe Cuzzupoli
wants to have another meeting on tooling. Would you come down?”
Well, I got there and McCarty isn’t there. I said, “What
happened to McCarty?”
He said, “I fired him. I want you to meet Charlie Ho.”
Charlie Ho was the new tooling manager. When we sat down, Charlie
Ho had a big, big book in his hand. Joe said, “You remember
your comments about modular tools?”
I said, “Yes.”
He said, “Take a look at Charlie’s book.” There,
over in Charlie’s book, he’s got a standard module, and
then all the end fixtures are standard. Then I go through his book,
and a beautiful job of designing modular tools. Then he said, “We’ll
put them in General Dynamics. We’ll put them up there at Grumman
for the wing. We’ll put them over here at Republic for the tail.
We’ll put them every place and we’ll use them at Downey.”
So they developed this modular tooling program.
At the end of the Shuttle Program, Joe called me. He says, “You
can’t get an award for modular tooling, can you?”
I said, “No, it’s a part of my job description. I can’t
get an award for that.”
He said, “Well, my people can. Will you and those JSC guys back
off and let us say it’s our idea?” So they collected $50,000
for the idea of the modular tool, but it was used throughout the program,
sure saved money. One of those things cost 3,800 bucks. One of those
modules just cost 3,800 bucks, and here 200,000 man hours at twenty
bucks an hour, that’s an expensive damned tool. Here they were
making them pretty cheap. But it got out of the business of having
all this different structure to analyze and so forth.
Then we had John [P.] Healy. Yes, John Healy was vice president of
manufacturing at Rockwell. He came in one day and wanted to make a
pitch on the windshield for the space shuttle. Now, that’s a
big windshield. He was proposing to have a riveted and welded-up structure.
Now, I remembered the LM problem with the window, and for a long time
we thought it was the frame, the window frames, something stuck on
a window frame that caused those windows to break, and I remembered
that. I listen to his pitch on his buildup of the window-frame, and
I said, “No way will NASA ever accept that. You go and propose
that, and I’m going to be right there to say no, no, no.”
He said, “Well, what do you want to do?”
I said, “You get a billet and you mill this whole thing out
of billet.”
He said, “You realize the size of the billet?”
I said, “Yes.”
“You realize the size of the machine?”
“Yes.”
“Well, there’s no machine like that around.”
I said, “Why haven’t you looked?” Well, they found
out they had five-axis froreep [phonetic] right there in Segundo [California],
and they found a contractor who would make the billets from which
to machine those windows. So they finally wrote the program and they
made a left-hand one and then inverted it to make the right-hand side,
so the software, the NC program was relatively easy to do because
they just had to work one side and then flip the whole thing and made
the other side. So they machined that in two pieces and then welded
it down the center. It turned fine, but, boy, if we had ever had a
window structure that was flexible, I would have worried about it
all through my days about that window.
Then we came to the point where we needed a thrust structure where
the engines on the Orbiter supplied a thrust into the Orbiter fuselage.
Joe came up with the idea of welding the thrust structure, and the
thrust structure was going to be titanium. In the Grumman’s
F-14, the wing carry-through boxes is titanium and it’s welded.
It took them year to get a process that would be satisfactory. They
were going to make lots of them, so they got this big automatic welding
machine. It’s bigger than this room. It has to done in a complete
vacuum, and everything has to be cleaned within hours of the weld
and so forth.
It was one tremendous undertaking. We could never, I don’t think
we ever get a thrust structure made if we were welding it. People
would be questioning this, questioning that. So they came up with
this idea of a diffusion bonded structure. Well, the airplane industry
had been using it for years. That’s where you just heat something
up so hot and you squeeze it together and two pieces of metal become
one. It’s a molecular bond as well as the one metal diffuses
into the other, and it makes a very good bond. Anyway, nobody had
ever tried this on a big structure before.
In the tooling world, you got these pieces that are going to squeeze
out. So when you make the structure, you’ve got to machine all
your pieces, and you’re going to squeeze them this way, this
way, and this way, and pieces are going to squeeze out. So you've
got to have in your blocking system, little rivulets that this material
can run into to that gets squeezed out, okay. So it’s a very
ticklish thing, and nobody at JSC would buy our concept of diffusion
bonding the thrust structure.
So it finally got to Chris Kraft. I remember telling him that if you
go back to the old Damascus steel, the way they made that was to get
it red hot and pound the hell out of it and it finally became one
piece of metal, you know, where you could take pieces and pound them
till you get red hot. Pound them together, that’s the way they
did it in the old days. I said, “It’s no different.”
So finally he said, “Okay, we’ll go do it.”
Well, the problem that came up was how do you test it? How do you
examine it for defects? You know, when you’re squeezing these
two things together, what happens if you get an air bubble or piece
for foreign material in there and so forth?
So Joe and I were sitting talking about it, and I said, “Why
don’t we make predetermined flaws in the thing. That way engineering
can put them where they won’t hurt anything. But if you can’t
find them, then your X-ray operation is no damned good. If you've
got a flaw in there that you know the size of it and you can find
it, then any similar flaws, as you do it, you should be able to find.”
So the engineers hid a couple of flaws. They knew where they were,
and they were on the drawing, but nobody knew where. None of the manufacturing
people knew where they were. We didn’t. Joe and I didn’t
really know where they were, and we didn’t care. We had to find
them. The guys had to find them. So that’s the way we did the
thrust structure. Got through all this malarkey about nobody ever
had a diffusion bonded structure before that big. We did that in El
Segundo area, and the whole thrust structure in there is diffusion
bonded. But machining that stuff to rid of that overrun, you know,
the stuff that’s squeezed out, that is a tough machining job.
Oh, the other thing about space shuttle, everybody was yelling about
cross-range. Everybody was yelling about cross-range, and I was a
newcomer. I got transferred from St. Louis. For the first in my life,
I was here at JSC. I’d never been assigned here before. I was
a JSC employee all these years, but I was always out there building
the hardware and doing the QA and so forth.
Anyway, I got to California, and it was in preliminary design. Now,
preliminary design is where you just get concepts, okay. The guy who
was the program manager at the time was Buzz [Bastian] Hello. Buzz
Hello. “Hello” just like you say, “Hello.”
He said, “Let’s go out to preliminary design and see what’s
going on on the drawing boards.”
So we got out there at the preliminary design, and everything I looked
at, man, it was a copy of the B-1 bomber with all the sexy shapes,
the Coke-bottle waist, and everything else, you know, curved wings.
All these concepts were out there, but they were all difficult to
manufacture. So I was talking to Buzz, and I said, “Can I get
up on this table and make a speech?”
He said, “Sure.”
So I climbed up on the table, and I said, “Everybody listen
to me. I see what you’re doing down there, but you’re
not going to be able to manufacture that stuff. Look at the B-1 and
you’ll see what kind of manufacturing problems they had with
all those curves and so forth. I want to see straight lines and I
want to see conic sections. If I don’t see that the next time
I’m up here, I’m going to break all of your French curves.”
And I stepped down.
Now, these guys I don’t think knew from Adam who I was, but
they knew who Buzz Hello was. When I stepped down, Buzz Hello stepped
up there and he says, “If he doesn’t break your French
curves, I will.”
The next time I got out there, there’s that boxy shape. Everything’s
straight. When Joe Cuz looked at the manufacturing problems on that
thing, he said, “You missed one thing. We got one sworfed [phonetic]
weld right under the windows.” The weld has two turns in it,
and that was the only place we had a problem with a non-straight line
or a non-natural curve. So the boxy shape came out of that one conversation
where I said, “I’m going to break all your damned French
curves,” and cross-range just came, you know. Cross-range wasn’t
fashioned by all this fancy work; manufacturing problems were. So
it got to be the boxy shape.
PPD has been a problem here at JSC. I say it’s a problem. It’s
a problem from my point of view, not from their point of view. PPD
always wants a backup. As I told you with the Air-Right [phonetic]
tanks, they start out with somebody. After they make a sufficient
number of mistakes, then they say, “Well, now I know how to
do it, so let’s start out with somebody else.” Okay. Usually
this is the one that finishes. So the Air-Right tanks were not flown.
Somebody else made the tanks in the end.
We had a problem with thrusters on the CSM and lunar module. On Gemini,
we had Rocketdyne making the engines and they wanted to go to somebody
else when Rocketdyne’s price got—originally it was 30
million. It got to be 130 million, and that’s no time to change
horses, after you put in that much money.
But on the space shuttle, they had selected Marquardt for the thrusters
on the nose, okay, and these were very delicately made engines. They
were welded, and they had insulation in the nozzles. They weren’t
ablative. They were reusable, okay, but the injector, the guys decided
to have Marquardt build injectors—the PPD told them how to build
them—and these injectors have fuel anoxidize and they have to
impinge in groups, like your gas stove, okay.
When they designed the tools under JSC’s direction, they designed
to make perfect circles, okay, but they never designed that every
hole would be lined up perfectly. So if you got this circle and that
circle that weren’t correct, or if they were crooked. It was
a big, big problem. Anybody would know that if you want to do that
right, you’d drill a hole this way and you’d drill a hole
that way at the same time so that you have them all lined up all the
way around this circle.
So Rocketdyne demonstrated that way of tooling it. So now they wanted
to quit Marquardt and have Rocketdyne build these engines after all
this development work by Marquardt. So we in management just said,
“No. Make the thing work at Marquardt.” So they used a
set of optics to put a pin in that hole and then line it up so that
the drill would be correct in the other hole. But PPD has done that
to us a lot, a lot of times.
Al Geweed was my man on mockups, trainers and mockups on space shuttle.
We built this great, big trainer of the crew compartment out in Downey,
and then we were going to ship it to JSC for the crew to use it here
in Building 9. Anyway, this was a big thing, and I was, being at Marquardt,
I was heading for Marquardt when Al Geweed got in touch with me and
said, “Hey, that thing is so big, we've got to cut it up, and
then when it gets to JSC, we've got to reassemble it. It’s going
to take eight weeks and a lot of money.”
I said, “Al, you don’t have eight weeks to get that trainer
ready for these guys. It’s late and they need the trainer. Find
out some way to ship it whole. You know, take it to a ship out there
in Long Beach and ship it from there.” Well, that turned out
to be a dud.
But I just happened to be driving past Van Nuys Airport, and I looked
out on the airport, and there’s the Aerospace Seattle’s
Guppy, the big Guppy, and doesn’t have any engines on it because
NASA owns the engines. We’ve always owned the engines for that
Guppy.
So I got to Marquardt and I placed a call to Al. I said, “Al,
you know, maybe there’s some way that Rockwell can get us to
put the engines on a Guppy, get it close to Downey as we can and load
that thing on a Guppy and then fly it to Ellington [Field, Houston,
Texas] on the Guppy."
Well, he called me back and he said, “Hey, they want four hundred
and some-odd thousand dollars for that.”
I said, “Four hundred and some-odd thousand dollars? From one
trip?”
He said, “Yes.”
And I got to thinking about it for a minute, and I said, “Al,
why don’t you just go and buy the goddamned thing? Go down to
contracts. Tell them to buy it. We’ll own it. We’ll put
the engines on it, and we’ll use it.”
I got a call back the next morning. He said, “Yes, we bought
it. It cost us 6 million.”
So they bought the airplane, delivered the thing to Ellington. Then
we delivered the airplane to Joe [Joseph S.] Algranti over there in
the Aviation Division [at JSC]. My phone rang for days. He didn’t
like that airplane for nothing. Finally the wings were giving way
on it. Marshall used it when we had the Challenger problem.
Marshall used it quite a bit for delivering big chunks of the engines
back and forth.
So the wings kind of wore out, and Joe parked it out in Biggs Air
Force Station out in San Antonio. A lot of my friends in the Air Force
there—I’m a member of the Officers Association here in
Texas—and a lot of my friends out there say, “You don’t
own it anymore. It’s our Super Guppy." So they own the
Guppy out there, and they’re proud of it in San Antonio.
But that’s how we got the Guppy. Al just kept pushing it and
convinced the contracts guys that in order to meet the schedule and
keep the cost down, it was better to invest in the airplane and get
that trainer here. It’s a shame Al passed away, you know. He
was head of our Rotary here for a while.
Oh, another thing that came up was on the ALT [Shuttle Approach and
Landing Tests]. I think Bob Thompson told you the reason for ALT was
the program was so light that we had to have something to attract
national interest. So that’s why we did the ALT. It was a useful
thing to do as well, but Enterprise got so heavy—I’m not
going to mention one name, but I’m going to tell you a story,
part of why it got heavy. You make lightning changes every time you
can, okay. But when the crew compartment for the first OV-101, the
first Orbiter, was put together, the skins are machined with integral
stringers, okay. In other words, it’s flat plate but then there’s
a T-stringer sitting up to strengthen it, okay. Then you roll them.
We had these made someplace and LTV [Aerospace Corporation] rolled
them in the right conical shape, and then we took out to Downey and
we welded them together.
Well, the first one they put together, instead of indexing the thing
properly so that the stringers were like this, they indexed the stringers
and went like that [Hobokan gestures]. I just happened to be at Downey
when Bill [William B.] Wilson, the Space Shuttle resident manager,
told me about it. He said, “It’s terrible. The indexing
of the tool was done wrong.”
So I called down here to the boss, and I said, “I’m going
to give them till overnight to come up with a solution, but in the
morning I’m going to tell them to cut it off and reweld it.”
Well, some manager here called out there and directed Bill Wilson
to go down and sign off the MRR before I got a chance to look at it
again. So they left it like that. Well, Bill Wilson was so angry that
he kept records on the result of that decision. When that decision
was made to leave it, these stringers had a design that tied them
together. Now they’re this way [Hobokan gestures]. That design
was no longer feasible. Now you have to have “Y”s, okay,
and you have to have Ys all the way around here to pick up those loads.
That was a big design change, costly to machine all that stuff.
After that piece was done, you had to apply secondary structure to
those stringers to hold equipment. Now they aren’t where they’re
supposed to be. Now you've got to do all that redesign. So Bill Wilson,
when it was all over, said, “That must have four months and
25 million dollars, just that one decision not to cut it off and do
it right." And he had all kinds of records he showed me about
the things that had to go on. So you can get some bad decisions out
of management at times.
I don’t guess Bob Thompson told you about the ejection seats,
did he? Did anybody talk to you about ejection seats on the Orbiter?
Butler:
We’ve talked to a couple people yet, but we haven’t that
part of history with Bob Thompson yet.
Hobokan:
Okay, well, you be sure you ask him about that.
Butler:
Okay, we will.
Hobokan:
Because there was a problem when we did the sled test. This fix was
relatively simple, but we had a real problem on the sled test.
Butler:
We’ll be sure to ask him about that.
Hobokan:
Well, I don’t know anything else of interest that I’ve
missed.
Butler:
Okay.
Hobokan:
Let me tell you about suing Grumman a couple of times. Well, there
was a change made on Apollo, or proposed change on Apollo. Lew Fisher,
to whom I referred before, the engineering manager for me, deputy
for engineering, came into the office one day, and said, “That
change we’ve been discussing, Grumman’s going to go ahead
and do it.”
I said, “No.”
He said, “Well, if you’re going to stop it, you’d
better come down now.”
So I said, “Take me to the meeting.”
We got in the meeting and Doc Tripp had his engineering team there
to go ahead and make this change. Grumman didn’t want to do
it. It was a dumb change. They had a much better idea, but nobody
down at JSC would listen. So when I came in with Lew Fisher, I said,
“Doc, I understand you’re going to make this change.”
He said, “Yes, we have no alternative.”
I said, “Yes, you do. You know, you don’t have to agree
everything that you get up here as direction.”
He said, “Well, we’re going to make it.”
I said, “Doc, that’s criminal. You know that you’re
doing something you know is wrong. To me, that’s a criminal
act.”
He said, “Well, what would you have me do?”
I said, “I’d have you pick up the telephone and call George
Low and tell him you don’t want to do it, that you've got a
better idea.”
He said, “Well, you think he’ll listen to me?”
I said, “Of course, he’ll listen to you. Pick up the phone
and call him.”
Now, he’s got all these people around there, and I’m arguing
with him over here at his desk, and it’s kind of an embarrassing
situation, but I knew he didn’t want to do it and I knew nobody
in that room wanted to do it. So I said, “Pick up the phone
and call him.”
So he picked up the phone and he called George Low. When George Low
answered, he said, “This is Doc, and I’m calling about
this change. I don’t think we ought to do.”
George Low said, “I don’t think you ought to do it either.
You know, I kept that in my desk for five days, and the only reason
I sent it to you is because I’m getting beat bloody down here
by the people who want to make that change. Do you have a better idea?”
Doc said, “Yes.”
He said, “When can you brief me?”
He said, “Tomorrow morning. I’ll have a team down there
at your office at eight o’clock and brief you on it.”
George Low said, “I’ll send you some paperwork to cancel
that direction."
So Lew Fisher got that accomplished. We had to stop it, and the only
ways to do it was to tell them, "That’s criminal."
Butler:
George Low was the kind of guy that would listen.
Hobokan:
Yes. And you know about the [Charles A.] Bassett [II] and [Elliott
M.] See [Jr.] disaster?
Butler:
Not very much.
Hobokan:
Did Tom Stafford brief you guys on that?
Butler:
We’ve only been able to talk with him briefly, and that was
a little more focused, I think, on his Apollo-Soyuz work.
Hobokan:
Yes, this happened in the morning. They were coming to St. Louis for
an altitude chamber test. The weather, it was Bassett and See in one
airplane and Stafford and Cernan, I believe it was or, and another.
Yes, it was Cernan. When they came into St. Louis, they came into
a landing system, but they were too fast. Stafford decided to out
and come into, I think it was 24, runway 24, and Bassett decided to
keep the airport in sight and just come around and land on 24.
I was in my office, and I heard this engine roar. My phone rang, and
somebody told me there was an accident out there. When I got out there,
the airplane was foamed and the nurse was already there, and I asked
her about the crew. She said, “No survivors.” So I asked
the firemen to slosh off the tail so I could get the tail number.
I called Dr. Gilruth, got Kenny [Kenneth S.] Kleinknecht and told
him that it happened. Then, of course, Tom and Cernan landed, found
out about it, too. So they were part of the team to do the failure
analysis.
Joe [Joseph F.] Shea was the manager of Apollo when the accident occurred.
About two days after the—no, I had come back from Downey, so
it must have been a little bit longer than that—but my secretary
come in there and said, “Joe Shea’s in your outer office
and he wants to talk to you.”
So I had him come in and he said, “I need to use your office
and I need to use your secretary for a while.”
I said, “Okay.” He was kind of shaken.
The secretary came running after me in a little bit and said, “He
wants me to call the White House."
I said, “Call the White House. Do what he asks you to do.”
Her name was Pat [Patricia] Goldstein, by the way. She’s still
here in the area.
She tried to place the call, but just about this time, I got a call
on another line, and it was Mr. Mac. He said, “I hear you got
a visitor from Apollo."
I said, “Yes, I have.”
He said, “You got everything under control?”
I said, “Yes, I have. I don’t foresee any kind of a problem.”
He said, “Ask him if he would go to Washington with me.”
I had told him he was trying the President, and Mr. Mac said, “Ask
him if he’ll go to Washington with me. I’ll get my private
plane, and I've got to there anyway. I’ll take him to Washington
with me.”
So I went out to see Joe, and he said, “Yes, I’ll go with
him.”
So we had the security guard come by and pick him up, take him to
Mr. Mac’s airplane, and they went off to Washington, D.C. I
think Mr. Mac helped him get done what he wanted to do up there.
We had been doing those kind of tests with the Gemini’s pure-oxygen
environment. I knew they were dangerous, but I didn’t know how
bad they were.
Yes, here’s the one about Ridenour. But that’s about it,
I guess.
Butler:
Looking back, when we were first beginning to talk today, you mentioned
how you were involved in the checkout on John Glenn's spacecraft for
Mercury. So jumping way back, what was involved in that process, in
that checkout process?
Hobokan:
Well, it wasn’t a very sophisticated vehicle, as you well know.
He had a hand controller that gave him some rate commands and position
commands. He had a periscope and a few things like that, but it really
wasn’t much except the radios and, as I said, we didn’t
have instrumentation. The KSC guys always ran off with that. We had
flown the chimps before. Yes, we flew the chimps before Glenn. But
there wasn’t much involved. It was a three-orbit thing, and
it was mainly the rocket shooting you up there and the retro to get
you down. So there wasn’t much, but somebody had to do it, and
I was the only guy there that was willing to do it.
For some of the Mercurys, the later Mercurys, we had pretty extensive
testing but I don’t where we stopped the guys from pulling the
instrumentation from us all the time, but McDonnell was getting tired
supplying VCOs. We had voltage-controlled oscillators for instrumentation
in those days, and every week we were shipping three and four of them
to the Cape because they wrecked them. McDonnell was getting upset
about that.
Butler:
That’s be understandable.
Hobokan:
But we used to laugh about John Glenn. You know, he ran the beaches
down at Cocoa Beach [Florida] a lot, and the big story at McDonnell
was he wasn’t running to do anything except lose the weight
that he had from all those steak and eggs breakfasts on the missions
that didn’t go. [Laughter]
Butler:
While the missions were up, Mercury, Gemini, and even into Apollo,
because you were at the resident office there at McDonnell and then
later at Grumman, what did you do during the missions?
Hobokan:
I used to go and be in Houston and visit the MER, the Mission Evaluation
Room, and just see how things were going there. Sometimes I went over
to the viewing room and talked to the—well, one of the guys
that I used to talk a lot with was Umberto—who wrote the book,
The Body Clock.
Butler:
I know who you’re talking about, but I’m not placing the
name.
Hobokan:
He and I used to sit there and talk about the astronauts getting acclimated
to the mission. Umberto—he gave me his books signed one time
over there in Mission Control. We used to talk to him, okay.
Then during Apollo, Dale [D.] Myers used to come down quite a bit.
Now, there’s an interesting story there. I was on the LM. Dale
Myers was Rockwell at the time. Apollo 10. The guys in the lunar module
had to change an LiOH [lithium hydroxide] canister. It didn’t
fit. Somebody had not fit-checked the canisters, all of them, before
the mission took place. There in Mission Control, the decision was
made to package that canister and return it back here via the CSM.
I was sitting there talking to Dale Myers. In fact, we just talked
about this the other night at Gilruth’s ceremony over here.
He was writing busily. So when splashdown came—a couple of days
later we had splashdown—he reached into his pocket and he pulled
out a piece of paper and handed it to me. It was a bill, and it said,
“LiOH canister, weight 2.2 pounds, packing and handling, $25,
shipping rate, $1 per mile times 250,000 miles: $250,000.” Added
it up and it come out to be $275,000, and it says, “Payment
due now.” So I took it and we had a nice laugh about it.
But then Apollo 13 occurred. I happened to be in Houston for Apollo
13. I was actually in the MER when I got a phone call. When I answered
the phone, it was a guy from Grumman. He said, “Mr. Hobokan,
how much water is in the PLSS?” The PLSS is the Portable Life
Support System.
I said, “With the problems that we’ve got, what makes
you want to know how much water is in the PLSS?”
He says, “Because you’re going to run out of water."
And I said, “Oh?”
He said, “Yes. Our projections show you’re going to run
out of water."
And I said, “I’ll find out for you how much water is in
the PLSS.”
So I went down to the place where they were plotting the ECLSS [Environmental
Control and Life Support System] stuff, and I said, “I just
got a call." [Robert W.] Fricke, the young man Fricke? Fricke.
Butler:
Okay.
Hobokan:
I said, “You’d better plot the water because I just a
call that we’re going to run out of water. I don’t know
how true it is, but someone ought to plot the water.” I've forgotten
the name of the contractor now that did the ECLSS work for us. But
anyway, they plotted the water and, sure enough, we were a day and
a half short. So Fricke came back to me and said, “He was right.
We’re going to run out of water.”
So I called the guy back and told him how much water was in the PLSS.
Then the guys from MER advised Mission Control and they started the
process of controlling the water usage and shutting stuff down and
so forth.
But when the mission was completed and they abandoned the lunar module,
I turned to Lew Evans, who was sitting there with me, and I said,
“I want you to prepare a bill for me. I want you to prepare
a bill that I can give to Dale Myers here for pushing the command
and service module around the Moon and on the way home.”
Well, we were sitting there and there’s a man there, a right-hand
man named Butch Voas. I don’t know if you ever heard of Butch
Voas, only man who ever commanded the Blue Angels twice. Lew said
to Butch, “Call Bethpage and have them prepare a bill and have
them data-fax it down here.” So they prepared the bill. I don’t
know if you ever read that bill.
Butler:
I’ve seen a copy of it.
Hobokan:
Yes, "Room with a view, jumper cables supplied, no charge."
You remember all that stuff? Anyway, when it got to Houston, unbeknownst
to me, Lew Evans signed it. The bill was actually signed and given
to Dale Myers. We were laughing about it here the other day, but he
didn’t know it came from him giving me the bill in the first
place. So he had given me the bill for the LiOH canister and that’s
how that reminded that it’d be fun to give him one back for
the lunar module pushing the command module around the Moon and back.
There was one other aspect of Apollo 13. The lunar module had incentives
on landing. You know, there were incentives on the mission. For a
successful launch, the Saturn V guys were given an award, won an incentive
award. For pushing the LM to the Moon, Rockwell would get an award.
For successful descent on a lunar surface, Grumman would get an award.
For a successful ascent back to the CSM, Grumman would get an award.
Then successful return and reentry, Rockwell would get an award. Well,
after the mission was over, Grumman didn’t get any of its awards
because it never separated from the command and service module, never
descended to the surface of the Moon, never went back up and redocked.
So Grumman got zilch out of that flight of all of its incentives.
But Rockwell did push the LM to the Moon, and it did reenter the Earth’s
atmosphere, and it did do the landing. They got their awards. So that
was interesting.
Butler:
Doesn’t seem quite fair.
Hobokan:
No, it wasn’t ever fair.
Butler:
Had there ever been any planning on your side with Grumman? Had there
even been any talks, any testing of the LM ever filling a role like
it did on Apollo 13?
Hobokan:
No, not that I know of. We did a lot of what-ifs, but mostly for other
purposes. You know, what if you landed on a rock? What if you landed
on a hillside? We did a lot of what-ifs. In fact, I got a call from
George Low one day, and he asked me how did I get along with Jim [James
A.] Chamberlin, and I said, “Fine. I’ve known him for
a long time, and we get along fine.”
He said, “Well, make an office for him up there and make all
of his interview arrangements. I’m going to send him up there
to do safety review of the lunar module. It’s going to be an
overview. It’s going to be in addition to everything else. But
I just want him to take an independent look.”
So, yes, we did have a case like that, but I don’t think we
ever expected to push the CSM the way it happened. But it shows the
flexibility of the mission controllers, and it worked.
Butler:
It shows that the good engineering and the safety that the LM did
end up having.
Hobokan:
Yes, the last thing that Jim [James A.] Lovell did before he left
the Aquarius, take the dive into the ocean, he said, was to reach
back and grab a piece of the netting. I don’t know if you ever
heard that, but he reached back and grabbed—we had netting so
that if they dropped something, it wouldn’t go behind the panels,
and he reached back and grabbed a piece of the netting. I have a piece
of it on a little piece of cardboard where he glued it down, signed
it, and sent it to me.
Butler:
That’s really nice.
Hobokan:
Yes, and I got a letter from George Low after the Apollo Program and
the problems I had with him and everybody else. It just said a simple
thing: “We never could have done it without your help. George
Low.” It’s a shame that we lost him.
Butler:
You’ve mentioned a couple of time some of the astronauts. How
big of a role did they have as you were working on the different spacecraft,
Mercury through Apollo? How much input did they have and how much
did you work with them to make it a spacecraft?
Hobokan:
Starting with Gemini, we had designated certain tests that they were
to perform themselves. Like the altitude chamber tests, they were
going to do that. Nobody was going to sit in for them. So we put the
primary crew through that altitude chamber test, and then the next
day we put the backup crew through that chamber test. We had to put
all new food in there and everything else and dump the urine and all
that kind of stuff. We put twenty-four crews through the twelve flights.
On Apollo we had them there for integrated tests all the time. They
came up and they went through the integrated test, the ones where
you simulate docking, the ones where you simulate descent, the one
where you simulate ascent. Nobody sat in for them. They came up there
and participated in those tests. It was difficult for us to get any
of the JSC guys. During the tests like that, you need a lot of people.
There were a lot of things going on, and you’d like to have
somebody from GN&C [guidance, navigation, and control], if you
have a GN&C problem, and the only guy we could ever come up there
was a young man named [Newton T.] Buras. He was a very nice young
man and he came up. He was in communications, as I recall. We never
had a “no” from him. When it came time for a test that
involved his equipment and Russ Clickner would call him, why, the
guy would come up and participate very well. You have Russ Clickner
down there? Russell [E.] Clickner.
Now, there’s a guy to ride the river with. I told you Liccardi
was my deputy for testing. But the real honcho of the test was Russ
Clickner. He's the guy could read octal with his eyes closed. He could
feel the heat of the bulbs, I think, and read octal. Anyway, he was
the guy that was responsible, and he had a bunch of Boeings working
for him.
I think the Boeings wanted a contract to NASA and to me, and they
were assigned to his department. One time when Wernher von Braun came
up, he wanted to know something about something, and I called Russ
to have one of his people come over and brief Wernher von Braun. When
the guy walked into the room, it was like a dangerous situation—not
a dangerous situation, a strange situation. The guy that Russ sent
over was one of Wernher von Braun’s friends from Peenemünde.
And all Wernher said was, “Can I borrow your office for a few
minutes?” And they sat down and they hadn’t seen each
other since they left. Russ sent the guy over there to do that.
The other thing about Russ Clickner, as I said, he was a real man
to ride the river with. When I came down here for Space Shuttle, he
was working over at POO, Don Arabian’s office, okay. We remembered
the problem of the test of the oxygen and hydrogen tanks that sealed
the switches on Apollo 13. It bothered us, you know, that it might
happen again.
In our conversations—by the way, let me digress just one minute.
That team in New York that I had on the lunar module, you know the
ladies still meet every month?
Butler:
Do they?
Hobokan:
Yes. Every month the ladies here meet. Every two or three months,
the guys meet with them. So my team, those of us who are still alive
are still meeting since the old Apollo days.
Butler:
That’s great.
Hobokan:
Yes. Russ came and was worried about testing and other people testing
your hardware. Now, that’s a big thing, you know. NASA spends
a lot of money on what is called sustaining engineering. That is,
somebody builds a GN&C box for you. The only guy that we would
allow to open that box and do any work in there was the guy who built
it. NASA would pay for the duration of the program to have those guys
who built that box on call to repair that box. Okay. It was called,
quote, “sustaining engineering.” They would keep the tooling,
the test equipment, and the people there. The people could be doing
something else, but they had to be available in case NASA wants them.
So Russ said, “Why are we allowing others to test hardware if
that has been our motive all the time?”
So I said, “If Rockwell’s making the Orbiter, Rockwell
ought to be responsible for the test, regardless of where it’s
done. Rockwell ought to tell them how to do it.” So we talked
about that a little bit.
One day he came over and said, “Hey, I have a way we could implement
what’s going on. Why don’t we have the maintenance requirements
all defined by Rockwell. Then we’ll impose them on KSC, that
they’ll do these requirements and they’ll do these in
this way.”
I wasn’t too computer-oriented then. I said, “How are
you going to do all of this stuff.”
He said, “Well, we’ll put a computer terminal at Rockwell,
one at my office, and one at KSC. We’ll have Rockwell write
the requirements and ship them to us. If we agree with them, we’ll
ship them to KSC. When they agree with them, it becomes a requirement.”
Then he said, “We could do that with a SRBs [Solid Rocket Boosters].
We could do that with an ET [External Tank].” So the OMRS system,
the Operational Maintenance Requirements documentation. He’s
the guy that started that because of some concern back there about
people ought to be responsible for their own testing, and Russ Clickner
was the guy that put the OMRS system together for us. Yes, he’d
be an interesting guy to—I think he came out of Wallops Island
[Virginia].
Butler:
And is he still in this area?
Hobokan:
I think he’s around here. He used to own a coin shop over here,
and his daughter was here not too long ago because she was a technician
for a dentist, Dr. Allen [phonetic] over here. So you might find him
through there. But he’d be an interesting guy to talk to, because
after he came down here, he went to POO. He didn’t like to sit
around. He liked to be in charge and doing things.
Butler:
Well, if we can just take a few minutes and we just need to change
out the tape real quick, and I have a couple of closeout questions
for you, if that’s okay. [Tape change.]
...came down here to JSC to work on the Shuttle Program. That was
the first time you were actually working here, even though you had
been employed the whole time. What was that experience like for you,
having been sort of part of the industry for such a long time, but
yet being a government employee?
Hobokan:
Very frustrating. [Laughter] Yes, I spent a lot of time in California
early on, as I said. The boxy shape, those things I could get out
to and do, but the tiles were a big job. I spent a lot of time with
Bob [Robert] Dotts, trying to get the tile system straightened out,
but I kept my hands in the business. I worked with [Robert G.] Chilton
over here in, I think, Building 13 or 16. He was worried about three
IMUs [inertial measurement units] functioning together when they’re
not all on the same axes, so we used to have lunch together and discuss
the problem. We finally decided to go buy a big multi-axis table so
that he could put it in Building 13 or 16 or whatever it was, and
then put the three IMUs on there and find out how they reacted together,
how you can tell one what its location is with respect to the others
so that they were all giving you the same coordinates and so forth.
But I did that.
Then I worked with—the back of the Orbiter was a high-noise
area. We had something like 163-decibel level there that would just
rattle your cage. We had a young man here, I still see him on occasion.
I can’t think of his name right off the bat. But he wanted to
put together a scheme that would test this stuff at high-noise level,
and he worked on some schemes that you took the noise and you combined
it and so forth. We took one of the buildings out here on Second Street,
and out of the project I would scrounge the money for him to go ahead
with this thing. He built this outfit over there, and when it was
all done, it could really put out the noise. But then he came back
and he said he could only run it between 2 AM and 4 AM because of
the power it consumed and so forth. But he’s an interesting
guy to talk to if I can think of his name. He was worried about the
noise.
Butler:
If his name comes to you later, you can always give us a call and
let us know.
Hobokan:
I think he was a mechanical engineer with a lot of dynamics experiences,
and he just was gung-ho on building that noise machine. But when I
was down here, I kept my hand in this all the time. I was always over
there working with the guys to make comments and look at their design
of the UTE and how they were coming along and out here in PPD kept
tabs on what they were doing, testing pieces of our engine stuff.
Yes, I didn’t sit in my office. That was the main thing.
You had Dan Mangeri [phonetic], I understand. He said he’s gotten
his stuff back from you. He was the guy that worked with Russ Clickner
in my team in New York. Then when Russ came up with the OMRSD, Dan
worked with Russ. But I said I wanted to make sure the system was
working first, so I retained signature authority for the Orbiter for,
oh, four or five months till I was sure it was going good. Then Dan
took over and he did the rest of it, but I kept in touch with that.
We had a problem with going for the ALT. How do you check out an Orbiter
at Edwards Air Force Base? Rockwell wanted to send a RF signal up
to the top of a mountain and back down to Edwards Air Force Base so
that we could use the ACE at Palmdale to check out the Orbiter over
at Edwards. That’s a concept that we had pushed for a long time.
We said, “Why do we have to have more than the LPS [large pointing
system?]? Why can’t that LPS at KSC bounce a signal off a satellite
and go to any factory in the world and check out a piece of hardware
so that they get first-hand checkout information? Why do we have to
buy a piece over here, a piece there," you know, and so forth?
So, anyway, when the Rockwells were going to do this, it was a 3-million-dollar
job to put up the antennas. I had Ed Bacca [phonetic] working for
me. He was one of my men from—you see, I kept all those guys
from the lunar module when I came down here, okay, and Ed [Eduardo]
Baca was doing GSE [ground support equipment] for me. Ed, I think,
is an electrical engineer, too. I’m an RF engineer, electrical
engineer, but RF. Anyway, we were talking about this thing. I said,
“Why the hell do they want to do that?” Well, they were
worried about airplanes taking off on the runway there at Palmdale
[California].
So I went out to Palmdale and I looked around for the high end of
the structures, you know. Heck, the buildings were tall, you know.
We got to Palmdale because the big tail on the Orbiter was sticking
up so high we had to get a high building. So I didn’t want to
go up there, so I had one of the Rockwell guys go up and take a picture
looking at Edwards Air Force Base, and we could see Edwards Air Force
Base, line of sight. So I talked to Ed again. I said, “No bouncing
off the thing. Just go straight across.”
Well, Rockwell disagreed with that, so I had them take a helicopter
with a radar altimeter and fly it right across the terrain between
Palmdale and Edwards Air Force Base, and it recorded that there’s
a valley between the two places, which further enhances the ability
to go line of sight. So Rockwell was still pushing the high-priced
system.
Ed Baca had a friend that worked at Goddard [Space Flight Center,
Greenbelt, Maryland], and he called his friend at Goddard. His friend
over there said, “Hey, we have relay stations. That’s
some of our business here."
So Ed Baca said, “Well, I need to talk to you about this.”
He got the charts and everything laid out and went over to Goddard
and, sure enough, Goddard had the equipment.
They said, “We can set it up. We have a tower." We put
a tower out at Edwards, and I think Baca got it done for something
like $300,000 and the rental per month was zilch. The system worked
beautifully. So, yes, the guys from Bethpage, if you turn them loose,
they could get a lot of stuff done, but Ed Baca got that done without
a problem and very cheap and it worked beautifully.
Butler:
Fortunate to work with a good group of people over your—
Hobokan:
Yes, you’re right. They were people to ride the river with,
and it’s a shame it got off to such a bad start, but I’m
sure it was just they didn’t understand Grumman the way some
of us did, and the people that were working and supervising them just
weren’t good managers.
Butler:
Certainly is a challenging program all throughout. Looking back over
your career with NASA, what would you say, throughout all these programs,
that was your biggest challenge, and then also what was your most
significant accomplishment, do you think?
Hobokan:
Well, I think the biggest challenge was the lunar module. It was in
such bad shape that just pulling it off—if it weren’t,
as I said in the speech on the anniversary of Apollo 10, if it weren’t
for Walter Burke and Mr. Mac, we never would have made it on time.
Those guys coming through for me was outstanding. But I knew Mr. Mac
well, and when I said I was in trouble, apparently he knew I meant
it.
Butler:
I want to just ask Kevin real quickly if he has any questions, and
then that’ll be about it.
Hobokan:
Okay.
Rusnak:
I did one or two. One of the things you talked about several times
is testing and the role of testing, the importance of it. For all
the programs, you got a certain degree of testing going on at the
plant, whether that be St. Louis or if that’s in Bethpage or
wherever. Then you’ve got another level of testing going on
down at the Cape. I understand that there were issues in terms of
how much testing to do where, and even if these sort of different
levels of testing were necessary, could you do them all at the plant
or whatever.
Hobokan:
Yes, there is a hierarchy of testing that you have to understand.
Number one, if a guy builds a black box for you, he’s got to
swear by that black box and everything that goes into it and everything
that comes out of it. So he does detailed testing on that black box,
and you hold him to requirements that are, like, 1 or 2 percent accuracy.
You can’t be from the mean more than 1 or 2 percent, okay, So
you do a very lot of testing and very detailed testing to very accurate
limits there, the guy who makes the box, okay.
Now, you say when I add this box to another box, the two errors may
add together or they may subtract from each other, and so the cumulative
error from here to there, I’ve got to have a wider range, okay.
In our business we call it the funnel. In other words, you hold a
black box manufacturer to 1 or 2 percent. As soon as he mates his
box to something else at the system level, the system level, you may
say, I have to go plus or minus 5 percent. At KSC I may have to go
plus or minus 7 and a half or even 10 percent. So you have this funnel
that you build at the start of your program and everything stays within
that limit.
Now, you have another big problem, and it was most prevalent, from
my point of view, on the Gemini Program. When you have people who
are frightened—and I don’t mean frightened that they’re
going to die in their automobile, but I mean they’re frightened
of making a decision that might cause some problem, okay. Now, in
the Gemini Program, very, very few of the people at JSC would accept
deviations. Now, when you build a black box, and you say, “This
is going to come out plus or minus 2 percent,” it has a range
over which it has to work, okay. Trying to hold it at plus or minus
2 percent over the whole operational range is not good. In fact, every
time you do instrumentation, you put instrumentation in a vehicle
that’s going to be read by Mission Control, you have to provide
a calibration for that specific instrument by serial number and location
to those guys. They used to call for a three-point calibration. You
take some point 5 percent within the lower limit and 5 percent within
the upper limit and in the middle. You give them that data and you
just tell them whether it’s curved that way, whether it’s
that way, whether it’s an S-curve. You give them some idea of
the shape and you give them those three points.
Well, during the Gemini Program, we found out that three points weren’t
accurate enough. So we started giving Mission Control five points,
the middle plus, you know, like a zero, one quarter, half, three quarters,
upper limit, and that works out pretty well for Mission Control because
now you’re not guessing at what that curve might be. They got
a pretty good feel for that.
Of course, today instruments are much better. They’ll do some
calibration on their own before a mission. Anyway, when you’re
doing a thing like a radar calibration at a factory, you’re
going to deliver a radar, okay, and you have range rate, angle rate,
ranging angle. You can’t always read those things on a straight
line, you know. They want angle. Down here they say, “I want
a readout angle so many volts per degree.” All right.
Well, when you make the machine, the machine may not be a perfectly
straight line. It may have some bumps in it. And you won’t get
people, who don’t understand that equipment, that will buy that
at the factory. If you let that prevail, everything’s late,
because you know the factory isn’t going to be able to fix it.
It’s going to be that way. Now, you’re not going to go
and change the spec, so you've got to say, “Okay, I’ll
buy it on a deviation and install it in a spacecraft and go.”
All right.
But on Gemini we could hardly get anybody to do that. So as the resident
office, our necks were on the block. We had to tell McDonnell we would
buy it. We had our own QC people and we reviewed that stuff. Jim [J.P.]
Harris [III], by the way, was our QC guy for vendors. So he would
come in and say, “Here’s the curve and it’s holding
up delivery."
We’d review the curve and tell him, “Sign it off. It’s
okay." But he would make us sign it, you know. Then he would
go and take care of it and get the stuff delivered. Had a very bad
name down here.
Chuck Mathews had a guy, name of Bob Lunt [phonetic]. I don’t
know if you ever heard of his name. Okay. Bob Lunt got up at the end
of the Gemini 25th reunion. All right. Chuck Mathews said, “I
want everybody in here to tell me what you did and how it contributed
to the program."
Bob Lunt got up and said, “My only job on Gemini was to stay
in St. Louis and spy on Andy Hobokan.” How about that?
Butler:
That’s interesting.
Hobokan:
Yes. So we were doing things to move the program. I went to lunch
with Chuck Mathews and Walter Burke one day, and we were walking down
a passageway, and Walter Burke was asking Chuck Mathews about something
that he wanted to do on the—I guess it was the Gemini Program.
Chuck Mathews said, “Why are you telling me? Why don’t
you just talk to Andy and he’ll get it done and I’ll never
hear about it.”
And I just turned around and left. I wasn’t going to be party
to a conversation like that. But, yes, when you’re trying to
do the job, it’s a lot different than sitting someplace and
complaining. But when I was here, I got around. I knew everything
that was going on, and if I didn’t, some of my people did.
Walt [W.] Jaderlund, you probably talked to him. Walter Jaderlund.
He was the head of structural testing in my office. He worked the
SSMEs [Space Shuttle Main Engines] and he worked the structural tests
of the Orbiter out in Lockheed’s facility in California. That’s
where we flew the bird. Hydraulically we never left the ground, but
we flew the bird, through all kinds of takeoffs and landings and everything
else. Jaderlund was our integrator for that. He was our interface
with the Mississippi Test Facility for the engine work, and he kept
good tabs on that.
I went to a special committee to oversee the SSME and I asked the
guy how they were going to qualify the engine. He said, “Somebody’ll
sign a piece of paper.”
I said, “That’s an incompetent answer."
And the Marshall guy that was head of QC got up and said, “I
agree with him.” [Laughter] So if you’re going to do things,
you got your neck stuck way out all the time. I think at that time
NASA was different than it is today. You know, you can’t find
anybody who will even let you stick your neck out. You get your head
chopped off before you’re allowed to stick your neck out. People
just want a 25-million-dollar study before you dot an “i”
because you've got to be sure it’s an “i” and you
got to be sure it’s a dot. Yes.
My son-in-law was a CO [commanding officer] of the fighter squadron
over here. He was also on the staff, the astronaut staff, here in
Building 4. After he was here six months, he said, “Even on
obvious things, I can’t get an answer.” So he quit. Got
out. “That’s enough.” Quit. Went to work for American
Airlines. So, yes, he reminds me every once in a while, he used to
fly some of the astronauts around, the non-pilot astronauts. You remember
the black girl, Mae [C. Jemison]?
Butler:
Yes. Mae Jemision.
Hobokan:
He said he was in the T-38 and his job was to take Mae up and put
her through a bunch of maneuvers. She had planned to do this, okay,
It wasn’t something he was doing, but he got assigned to be
her pilot that day, and she said, can she operate the radio. He said,
“Offhand, I said, 'Sure, you may.'” So they got out to
the end of the runway and Mike [Hobokan] said to her, “You can
call the tower and ask for permission to take off.” He said
Mae got on the radio and said, “Hello, tower. This is Mike and
Mae. Can we go now?” [Laughter] He said he was trying to scrunch
down in the cockpit so nobody would know it was him in there. But,
anyway, she said, “Hello, Tower. This is Mike and Mae. Can we
go now?” [Laughter] But he didn’t stay long. He just felt
the current environment wasn’t good for that.
Now, you got some people here that are working hardware and structure
that are doing a good job, and that’s the X-38 people. I think
you got some people there that are willing to maneuver and get out
and get things done, and I think that they’re working pretty
well.
Got any more? Did I answer your question on the funneling?
Rusnak:
Yes. Related to your days at Gemini, one of the original goals for
the program was also to prove the ability to land on land instead
of in the water. So I was wondering how you as someone who would be
interested in how you’re going to actually apply this to the
capsule, what you thought of the things like the paragliders.
Hobokan:
Well, at that time, you know, the paraglider was being used a lot
by people. We watched a lot of people run around with those things
and dive off the damned cliff and soar around in it. It looked pretty
good. It was called the Rogallo wing. The Gemini was supposed to land
on land, and it landed on skids, not skis, not wheels, okay. The Gemini
was supposed to have a parachute, then deploy the Rogallo wing, and
then by moving the CG [center of gravity], you could take it down
and land on the skids.
The skids were an interesting design. The skids were not straight.
The skids were angled, and one of our big problems was to find out
what that right angle was. Now, when you’re skidding down there,
if both skis are tipped at the same angle, the friction here and the
friction here is the same [Hobokan gestures]. So it’ll go straight.
But now if it starts to wallow and this one goes that way, then you
get a lot more friction here and it tends to straighten you out. If
it overshoots, you get some more here and you kind of—okay.
So one of the big things was to get that skid angle correct, and we
did a lot of work letting it come down on a swing and, you know, on
a line with pulleys and hit the ground and go off. So, yes, we were
very, very enthusiastic about that.
Rockwell caught the job to do the Rogallo wing, and at JSC here, one
Scotty [H.] Simpkinson was working with quality and safety with Rockwell.
Scotty kept reporting to us that they were having trouble because
of the number of sequences that it had to go through. First, you had
to deploy the drogue chute. Then you had to get the wing up, wing
deployed. Then you had to fill the wing, you know, with gas. Then
you had to get rid of the parachute and then you had to do this, then
you had to do that. Well, deploy the landing gear.
As I understand it, there were some twenty-one sequences that had
to be accomplished to do all of this, and Rockwell had trouble getting
past fourteen or fifteen of those sequences. They never could get
through this chain of sequences reliably. So the monies that were
going into that program were canceled, canceled on the Rockwell side.
Then we gave up the skis, the skids, skis, the deployment mechanism
for the skis. When you’re on a Rogallo wing, we had to have
a lanyard come all the way down between the hatches and hook onto
the nose so that you were holding two lines aft and one line forward
so that you held the vehicle pretty level. Okay.
So when the Rogallo wing effort was terminated, then the skis were
terminated and then that’s when McDonnell said, “Hey,
if we use those attach points, we can tip the vehicle this way and
we can enter the water on the point, and you’re not getting
this bang like we did on Mercury and Apollo. You could land on the
point, the corner of the heat shield in the body. Then you get a much
nicer entry, and you don’t get that sharp jolt."
But we were really keen on doing the paraglider and the skids, and
we were a long way along on the Gemini side of the house. It was the
Rockwell side trying to get that job done that stopped it.
Now there’s a corollary here. Rockwell with the B-1 was trying
the develop an ejectable pilot crew capsule, if you remember, early
on. Never did get that to work. The B-1 doesn’t have that ejectable
capsule. They had planned to eject the crew as one piece and have
it come down on a parachute, but they were never able to get that
going. That was Tom Healy [phonetic]. Tom Healy went to do that job
and never got it. So there are two things that Rockwell had tried
like that, and neither of them worked. Now, they did make the ejection
seats work on the Gemini, but you be sure to ask Bob Thompson. If
he doesn’t answer your question, call me.
Butler:
Okay.
Hobokan:
It was a real, real blow when we saw those sled tests. Yes, but I
want him to tell you.
Rusnak:
Okay.
Butler:
Well, we’ll be sure to ask him.
Hobokan:
Let’s see. Anything else?
Rusnak:
No, those are all the question I had. Thank you.
Butler:
Thank you very much for coming and talking with us and sharing your
experiences.
Hobokan:
Yes, it was interesting.
Butler:
It was very interesting.
Hobokan:
The whole business has been interesting.
Butler:
Would you ever have imagined where your career would lead you?
Hobokan:
No. When World War II started, I didn’t figure I’d ever
survive. My brother and I figured we were going to get drafted and
that’s the end of that. But from all of my family, we all survived.
My brother and I and my sisters, two brother-in-laws survived, and
it worked out fine.
But, I’ll tell you, sub-hunting in convoy isn’t fun. We
spent the first part of my career sub-hunting and trying to find out
where these submarines were getting refueled down around South America.
So we spent months anchored out with our airplanes night and day searching.
We got all the way down to Argentina and that’s where they were
getting refueled.
Okay.
