Interviewed by Rebecca Wright
Houston, Texas – 9 March 2009
Wright: Today is March 9,
2009. This oral history with Bill Reeves is being conducted for the
Johnson Space Center Oral History Project in Houston, Texas. Interviewer
is Rebecca Wright, assisted by Sandra Johnson. Thanks again for joining
us this afternoon, and we’d like for you to start by talking about
your background and what led to your interest in applying to the Manned
Spacecraft Center.
Reeves: I grew up as a child
of the 1960s in junior high and high school, and I graduated from high
school in ‘62. I grew up in Arkansas, northeast Arkansas, and
had never been anywhere. Of course, I can remember the first launch
of Sputnik [Russian satellite] and the news about it. That was the starting
of the whole space business. It got my attention, but at that time I
was in junior high. I was very interested in it, but I was also one
of these kids that was always interested in engineering and taking things
apart and doing things, and seeing how everything worked. I was always
that way as a kid, mostly because of my dad.
My dad didn’t have a formal education beyond high school, but
he could do anything, so I learned a lot from him. I knew at a very
early age that I wanted to go into engineering. That appealed to me.
That was the line of work I wanted to get into, as much as I understood
about it.
When I got out of high school, I went to Arkansas State College, which
was in my hometown of Jonesboro, Arkansas, to take what was called a
pre-engineering course. You couldn’t get a degree there, but you’d
get the first two years. I knew I wanted to go into electrical engineering.
I took the first year at Arkansas State, but then I realized I was going
to lose a lot in transferring to another college. I wound up going to
Oklahoma University [University of Oklahoma, Norman Oklahoma], where
I went another four years to get a bachelor’s degree in electrical
engineering.
When it got close to time to get out of college, in my last year which
was 1967, I was interviewing every company that came by. OU had a terrific
placement program. There were a lot of companies that came. I interviewed
with lots of people. I really wanted to interview with NASA, but NASA’s
docket was full and I couldn’t get on the interview list. So I
just picked up one of the government forms, and filled it out and mailed
it in. I wound up getting interviewed twice over the telephone, and
I was very interested in NASA. A guy from my hometown, who I went to
high school with had gone to OU. He graduated a semester ahead of me
and came to NASA here in Houston. We talked, and he was telling me how
great it was. I really wanted to go to the southeast United States,
and I had my eye on Texas or Florida. I wound up getting interviewed
twice over the telephone, and then I got an offer to come to work for
NASA via telegram. I still have it.
I accepted the offer to become a flight controller in the Apollo Program.
Now, of course I was graduating as an electrical engineer, had absolutely
no idea what an electrical engineer did, had no idea what a flight controller
did or what it was all about. I just knew I was going into Operations
and I was going to be working on the Apollo Program, which appealed
to me. When I got here, it was in June of 1967, and at the time, I went
into the LM [Lunar Module] Systems Branch and Flight Control Division,
where we were in charge of the Lunar Module. I was assigned to the electrical
power system group; we were responsible for the flight operations of
the electrical power system of the Lunar Module and all of the pyrotechnic
systems on the Lunar Module.
I'll never forget it. I got here, got sworn in, showed up in Building
45 in the room they told me to go to, and I was put in a room with four
other guys that worked on that particular system. One of them was a
guy named Bob [Robert D.] Legler, who was a Philco-Ford employee at
the time. There were a lot of contractors with NASA, and I was civil
service. Bob had been around forever. He was here in the Mercury Program,
Gemini Program, and he really became my mentor. He took me under his
wing and really started teaching me everything he knew and helped me
a lot.
My first assignment when I walked in—you walk in as a new employee,
and they give you a desk and they give you a big stack of books and
pencils and papers, and you don’t know what you’re going
to do. I didn’t know a Lunar Module from a school bus, and so
the first assignment they gave me was converting the actual systems
drawings that Grumman—that was the contractor that built the Lunar
Module—built the vehicle from, to operational diagrams for the
handbooks that we would use on console to support the mission real-time.
Taking these real complicated wiring drawings and simplifying them.
Quite frankly, the background I had just worked with electrical schematics
and [my experiences in] tinkering with things was more help than my
college education on that, because that was really right down my alley.
I picked up on it really well and got immediately into it. They gave
me an assignment on particular parts of the system, and so I would work
on that.
In those days, we didn’t have computers or anything. Everything
was done out on a tabletop with a pair of scissors, scotch tape, pencil,
and paper. You’d make the drawings and tape them together, then
turn them into the draftsman, and the draftsman would make them pretty
and print them up and make them the right size and everything. We used
to have these big drawings in the hallways taped to the walls, all up
and down the building and all around the room, and that’s where
you would work on the full-scale drawings. None of this computer, CAD
[Computer Aided Design] stuff or anything they’ve got nowadays.
At the time I had gotten here, it was right after the Apollo 1 fire.
They were in the downtime after the fire and trying to recover from
it. We were coming up on the first launch of a Lunar Module, which was
an unmanned, Earth orbit test flight. So I got familiar with the system,
and then went through all kinds of training. The Flight Control Division
had wonderful training where they’d train you on all the different
systems, and the console operations, and how the network worked, and
all that. At that time we didn’t have TDRSS [Tracking and Data
Relay Satellite System] satellites like they’ve got now. We didn’t
have anything. There were no satellites.
We had remote sites all around the world, and the flight controllers
would actually go to the remote site. As the vehicle came over the horizon,
you’d have control of it while it passed over your site. Then
after the flight, you’d pick up the phone and call in a report
on what happened. I missed out on that because when I got here, the
first mission that we were supporting was the last flight for the remote
controllers to go out to the sites. Some of the group that I was working
with went out on some of the tracking ships to some of the remote sites.
But then they started scaling all that back, started having resident
people at the sites that would call in and take care of the passes.
Then, of course, later we got TDRSS satellites up after Apollo and started
relaying all that information in.
My first mission was the first test flight, unmanned LM, and that was
pretty exciting because it was all done by commands. You would send
commands to the system and have it perform and do the things that you
wanted it to do, and you’d collect all the data on it. Things
were really different then because, like I said, there were no computers.
In the whole Control Center, there weren’t any computers. All
the computers were the big mainframes downstairs that handled all the
data or the mainframe computers over in Building 12 where they did analysis
offline. We didn’t have desktop computers; in fact, the only thing
we had on the console was an old Friedan mechanical calculator that
you’d punch in the numbers and pull a handle, and everything on
it moved.
Wright: They’ve become
infamous, haven’t they?
Reeves: Yes. That’s
quite an antique now, probably, but that’s all we had for calculating
stuff. We would do trend plotting by looking at the data on the screen
and looking at the clock, and have a piece of graph paper on the console
and you’d plot points. I've always thought you actually knew the
systems better then because your head was right in the middle of the
system at all times. You knew exactly everything that was going on,
and today we rely so much on computers that we’ve gotten away
from some of that. We don’t think about it as much as we did in
those days.
Wright: Were you in the Staff
Support Room on that first mission?
Reeves: Yes, I was in the
Staff Support Room all through Apollo. I never did go to the front room
during Apollo. By the time I got here, the teams had been pretty well
established. So I was in the pecking order, and it took a while to work
your way through the back rooms and into the front rooms. The front
rooms were staffed pretty much by people who had been here through Gemini
and were more experienced people. I did get rapidly to the point where
I was pulling shifts on flights from the Staff Support Room; in fact,
by Apollo 11, which was in July of ‘69, I was already pulling
shifts. I was on Glynn [S.] Lunney’s team on Apollo 11 when we
landed. I wasn’t on the shift that landed, but I was there in
the room the night they landed because I was coming on as soon as the
landing shift went off. That was quite a night. We all knew we were
making history, but we all had a job to do and we were just doing the
job. But you had to think about what was really going on and what you
were really about to do. You’re doing something nobody had ever
done before, and that was pretty fascinating.
Wright: Can you give us an
idea of what people felt? Especially for someone who had worked on the
LM system.
Reeves: Nobody knew what
to expect really. We had landed Surveyor [robotic spacecraft] on the
Moon and had some unmanned stuff and some photos from the Moon. But
nobody really knew what to expect. It’d be like picking a place
to land out in Arizona somewhere and thinking the whole Earth is like
that. You never know. Even if you have a lot of knowledge of one place,
you don’t know exactly what you’re about to do, so it was
the unknown that got everybody. By knowing the vehicles and knowing
the systems as well as you did, you knew also what the limitations were.
We knew we were taking big chances. When I look back with what I know
and the sophistication of the vehicles we fly today—I look back
at how simple those vehicles were and how little redundancy we had in
some major systems and things. It was pretty gutsy. We were really taking
some chances, but they were calculated chances. They were risks, but
in order to do what we had to do, you were willing to take those chances.
Wright: From the time that
you arrived to the time that we landed on the Moon, that was just, just
two years, but it was two full years. Can you give us an idea of your
schedule? Did you come here by yourself, or did you bring a family with
you when you came?
Reeves: Yes, I was married
at the time. We came down, had an apartment down in League City [Texas].
Like I said, I grew up in Arkansas, a pretty sheltered life. I had never
been anywhere, going to school in OU. When I came down here, it was
the only two places I’d ever been in my life.
I remember my first paycheck, which looking back on it now was hardly
anything, but it was more money than I’d ever seen in my life,
and so it was good. It was a great group of people we were working with,
a lot of extracurricular activity. I got involved. We had a flag football
team, and all of the different branches in the Flight Control Division
and some of the other divisions would compete. We used to go out to
Ellington [Air Force Base, Houston, Texas] and play flag football, lots
of picnics and things like that. It was a good life. It was very good.
The other thing was the crews. We worked directly with the crews, which
was nice, because in those days there were very few crew members. There
were a dozen or a couple of dozen at the most by the time Apollo was
over. We would work directly with the crew members and even brief the
crews on our systems before they would go down for the launch. You got
to know the crew really well, and that was good. That stayed with me
my entire career. I still today associate with a lot of the crew members
that we worked with back then. There’s getting to be fewer and
fewer of them, but John [W.] Young just left not long ago, and we used
to work with him a lot. Worked with all the crews. They were great.
Wright: Did that help when
the crews returned, for you and your group to receive input from the
crews of how your systems worked?
Reeves: Yes. We’d have
debriefs, and private debriefs with them if we had some issue that we
wanted to talk about. Then there were always the big splashdown parties,
they called them in those days, that whenever the crew would get back
here, there were always the big celebrations for the mission, and those
were nice—where you’d really get to know them personally.
It’s interesting to see where a lot of those people went in the
program. A lot of them became top managers later. There was always sort
of a gap between my class, when I came on, and the generation ahead
of me. The generation ahead of me were the ones that actually founded
NASA. They were the original group that came down to Houston from Virginia,
and formed Houston Manned Spacecraft Center. There was always a little
bit of a distance, separation, age-wise and experience-wise between
my group and that group.
I was in one of the last major hiring groups that they hired for Apollo.
I think they pretty much closed off hiring in large groups after that,
because they had all the people they needed to fly the program. There’s
always small groups after that or small hirings, onesie, twosie stuff.
I was in a group of—gosh, I don’t even remember how big
the group was, but I remember the swearing-in ceremony where you swear
in as a civil servant. There must have been fifty or sixty people there,
so it was a pretty large group.
Then I worked every one of the Apollo flights from the Staff Support
Room. I was on for Apollo 13 when that accident happened. It happened
right during as shift handover. I was coming on and Bob Legler, who
I mentioned earlier, he was the EPS [Electrical Power System] guy that
was going off-shift and I was coming on-shift. You have about a one-hour
handover where the preceding shift goes over their notes and hands over
anything that’s going on. Then you get comfortable and you tag
up with your front room operator after you’ve gone through your
handover notes, and there’s a big tag up. So it’s a pretty
regular thing that happens.
We were right in the middle of that handover briefing when the famous
words were uttered, “Houston, we’ve got a problem.”
I had already sat at a console. Legler was standing up behind me. There
was a strip charter recorder between me and the guy on my right, Dick
[Richard L.] Brown, who was in charge of the power system for the Command
Module. We looked over at his console, and his console was all lit up.
All the limit lights and everything were on because of the explosion.
He looked over at us and, he said, “You guys better be getting
ready to power the LM up from a dead vehicle, because we’re going
to be out of power in thirty minutes.” Then he followed up with,
“I will bet you any amount of money that oxygen tank just blew
up.”
He knew that because the oxygen was stored cryogenically in tanks, and
on the trans-lunar coast as you went to the Moon, in zero gravity the
cryogenic oxygen would stratify and it starts layering at different
densities, which affects the performance of fuel cells. So every once
in a while, they would stir up the cryos. They had a stirrer inside
the tank and it was manually turned on with a switch and they would
stir it up. They can tell when they need to do that by the fuel cell
performance. Dick had just told the front room to pass the word up to
have the crew turn on the stirrers in the cryo tanks, and that’s
what caused the explosion. A short in the stirrer motor inside that
tank. He knew right off the bat what had happened. He didn’t know
the severity of it, but he knew he was losing oxygen and he knew that
he was losing power.
Without getting into a lot of technical detail, the problem is during
trans-lunar coast, there was a set of umbilicals that the crew manually
connected between the Lunar Module and the Command Module. The LM received
just a small amount of power from the Command Module throughout the
coast just to power some heaters. That was the only power the LM had
on it. The LM was all batteries. There was one switch inside the Command
Module called the CSM [Command and Service Module]/LM power switch,
that when they got ready to go into the LM and activate the LM, they
would throw that switch. Using Command Module power, it would turn on
all the relays in the LM and bring the batteries on the buses and power
up the LM.
Well, when the explosion happened, the first main power bus in the Command
Module that they lost was the bus that powered that switch, so there
was no way to turn the LM batteries on from the Command Module. That’s
why he said, “You’d better figure out how to power a LM
up from a dead vehicle,” he says, “because our bus is gone.”
So Bob and I sat there and, real-time, we wrote up the procedure for
how to power the LM up from dead. It had never been done before, and
you had to trick the system. That gets kind of convoluted so I won’t
get into all the details, but you had to go through some tricks to do
that in terms of what equipment you would unpower by pulling circuit
breakers. You had to turn an ascent battery on and get a bus hot in
the LM, and then use that power to turn the descent batteries on, and
then turn the ascents back off.
We wrote that procedure out and then passed it out to the front room,
and they talked the crew through the procedure. That’s one of
the big differences between the Apollo 13 movie and the real world.
In the movie, it looked like the crew just went into the LM and said,
“We need to power the LM up.” Well, they didn’t know
how to do that, and so in the real world the way it happened was, we
talked them through the thing.
Wright: Was this something
that—since you had mentioned the word earlier about simplifying—was
this something that was simply just between you and Bob, you could sit
down and simplify this and put this together in a matter of minutes?
Reeves: Well, we knew the
system so well. I mean, we lived with that system. Also, in retrospect,
you look back at it and you think, “How in the world could I have
spent an entire career, for years, working on this system when it’s
so simple?” (laughter) But there was a lot to it.
Wright: It was simple to
you, but it may not have been to everybody else.
Reeves: We were able to sit
down and we knew what the problems with it were, and what to watch out
for, and we were able to write it out. In the real world, when you’re
writing a procedure for something, it goes through all kinds of tests
and verification in the simulators and all that. We didn’t have
time for any of that. I mean, we knew for a fact that we had to have
a procedure on board in about thirty minutes, and so we were under the
gun. We just had to write it out, and nobody questioned it. Nobody even
thought about questioning it. They just read it and talked the crew
through the switches and just did it.
That brings up another thing that—and my message has always been
to young people coming into the program, you never know what you might
work on or some idea that you have, how it may affect something in the
future. Remember when I told you my first assignment was doing the simplified
drawings? Well, one of the assignments my section head had given me—or
my group leader—was he said, “We don't have any drawings
for how to separate the Lunar Module from the Saturn vehicle, and all
those circuits, and how the interface between the Command Module and
the LM works.” He said, “Why don’t you focus on that
and come up with those drawings?” So those were the drawings I
was trying to make.
In the process of doing that, the two umbilicals I was telling you about
that the crew mates up between the two vehicles—whenever I figured
out that’s the way it was designed to work and was talking with
the Grumman engineers and everybody, it dawned on me that if all of
the heaters in the LM were to come on at once—which is within
the realm of possibility, it just depends on temperatures and the duty
cycle of the heaters—that the fuse to those umbilicals wasn’t
big enough. It would blow the fuse and you’d be out of business,
so I flagged it, I wrote a RID [review item disposition] against the
vehicle and flagged it as a problem with the design. It went to all
the right boards and stuff and they wound up picking up some extra,
unused wires in the umbilical, and they hooked some bigger fuses in
and ran some more wires, which seemed totally insignificant at the time.
But it turns out on Apollo 13, right after the explosion and until they
got control of everything, when the fuel cells died on the Command Module,
they had to turn on the entry batteries to get some power to do some
things. The entry batteries are the batteries they use during reentry,
and once they’re gone, they’re gone. Well, they used some
capacity out of them. I don’t remember the number now, but they
did use quite a bit of power out of them. This became a big worry as
we were trying to figure out how to get them back, and what we were
going to do on entry. We came up with a way to use excess battery power
we had in the LM to recharge the entry batteries in the Command Module.
You did it by, again, tricking the power system out and running LM battery
power back through those umbilicals to the Command Module to power the
inverter in the Command Module, to step the voltage up high enough to
where you could charge the entry batteries and get the battery charger
working. In retrospect, had we not increased the size of those umbilicals,
we wouldn’t have been able to do that.
I'm sure we would have come up with some other solution, but it’s
just ironic. That very first assignment I had was where I found a problem
that later turned out to be a player in the Apollo 13 accident.
Wright: On that procedure
that you just talked about, did you test that one?
Reeves: Yes, we tested it.
We had time to test it then, during the mission, because we had several
days to work it. That was one of the most exciting things I've ever
done, was worked on Apollo 13 in that problem. There was a psychological
thing that came up in that mission to me. I was interviewed by the team
that put the Apollo 13 movie together. They came out here and interviewed
people who had worked on the flight when they were writing the script
for the movie. I had told them this in that interview, but they didn’t
use it. But it always struck me, and I had talked to several other people
that were there and it struck them the same way.
In the main room and on all of the TV tubes, there was a clock or a
counter up over the main board, the main screen, that was “Miles
from Earth.” As the vehicle was going outbound toward the Moon,
you’d see this counter counting up, the number of miles from Earth.
Of course, the explosion happened on the way to the Moon, and the fastest
way to get back was to go ahead and loop the Moon and come back. It
was a day after the explosion, the counter was still counting up. You
were going the wrong way. You had this major problem, and you wanted
to get that crew back and you wanted to get them back home, but they’re
going the other way.
It just struck a lot of people, myself included, as very disconcerting
that you’re going the wrong way, even though everybody knew that’s
the right thing to do. Then when the vehicle looped the Moon and it
started coming back and that counter started counting down, there was
a noticeable change in everybody’s emotion or the way people were
thinking. Everybody was really, really worried going out that we weren’t
going to be able to pull this off. When you were coming back this way,
you started feeling like, “Hey, we’ve pulled this thing
off. We’re going to be able to do this.” It just really
struck me as something that stuck in my head and it’s been there
ever since. I remember that very distinctly.
Wright: Were you there for
the duration of the mission?
Reeves: Yes. I was in the
Control Center for every minute of every Apollo mission. They had a
dormitory in there in those days, and you could go in there. You didn’t
have an assigned bunk. You’d just go in there and find an empty
bunk and you’d sleep. I ate, slept, and breathed that program.
I was there. I didn’t want to miss a minute of it. I was on one
eight-hour shift out of twenty-four. I was there for the other two shifts
and I’d go grab some sleep and come back. Anytime the crew was
awake, anytime an EVA [Extravehicular Activity] was going on or anything
going on, I was in there just taking it all in.
I was a real space nut in those days. I still am, but I remember when
I got here, I’d go over to the library and check out movie reels
of flight test programs and Mercury and Gemini, and I would check out
a projector, and I’d take them home and I’d just sit and
watch hours and hours and hours of these old flight tests and movies
of previous missions and things. That paid off. It’s just good
experience, and it was all available to you. You could get anything
you want.
Wright: I have to think it
gave you a deeper understanding of where the program had been and where
you had come in.
Reeves: Yes, and you fill
in a lot of blanks of how you got to where you are. The evolution is
very important as to how you get to where you are. Then as you stay
here for 42 years like I have, and you see the pendulum swing back and
forth and different programs come and go, you hate it, you hate to repeat
mistakes that are so obvious from the past. But we do that. There are
good reasons why we do it, but you wish you didn’t have to do
that. At least you know where the mistakes are and you know what the
outcome was, and it helps you. It helps you a lot in trying to put some
sanity to what you’re doing.
Wright: You helped to design
the controls and displays for the console.
Reeves: Yes. That was the
flight controllers’ jobs. You had to do your own tools and make
your own tools. The controls and displays, even back then, were much
simpler than what we have today. I mean, when you looked at the CRT
[cathode ray tube] or the tube on the console and you looked at the
data, it was a list of parameter numbers and the value and what the
value meant. It would be a parameter 2V-6000-4T or something like that,
which is a temperature. Then it would be a number that was the number
of degrees, then it would say over to the side, “Degrees F,”
or, “Degrees C,” or whatever. It was just columns of numbers,
and those were the displays that we were putting together in those days.
It was just taking all the telemetry data and putting it into a format
that you could look at on the tube and make some sense out of it.
Then later, way on down the road when I got into Shuttle—all flight
controllers do this. You influence the displays that you’re going
to use real-time on the console. Of course, in the later years you had
more sophisticated tools and you could make diagrams and do all kinds
of things with them, different colors. Back in Apollo, you didn’t
have different colors. You had one color. It was green or green on a
dark background. That was it. So it’s just things were so different,
so different.
To send a note from the Staff Support Room to the Front Room, we used
a pneumatic tube system. You’d write the note out on a piece of
paper and you’d put it in one of these carriers, and you’d
put it in this pneumatic tube system like you see in banks and things.
You know, a drive-in bank where the tube goes up the tube? We’d
send notes back and forth from the Main Room, or over to the Computer
Center, or to other Staff Support Rooms. There was a network of this
pneumatic tube system in the building, and that was your email in those
days. Just everything was so different from what we do today.
Wright: Well, another type
of a tool is the operational handbook. Did you help also put those and
the mission rules together, some of those?
Reeves: Yes. Again, all flight
controllers do that for their system. You write the procedures for how
to operate the system, and then you write the malfunction procedures
where you “what-if” the system and you put the drawings
together. Then you “what-if” the system and say, “Well,
what if this doesn’t work? What if this breaks, then what do you
do?” We would build the malfunction procedures that we’d
use real-time, so if you get this light on, you get this indication,
then it tells you steps. It’s all pre-thought out so that you
can do it real-time. If you didn’t do that, you couldn’t
do this real-time. We still do it today. It’s the same way we
do it today.
Then you write the flight rules, which are the rules that, again, are
pre-thought out, conditional problems and you think through them and
you say, “Well, if this happens, here’s what I'm going to
do. If this happens, here’s what I'm going to do.” So you
write those, you write the flight rules and you capture those rules.
Each flight rule in the flight rule book today that governs Shuttle
and Space Station, every flight rule represents hundreds of hours of
debate and discussion, panel meetings and board reviews. It’s
just amazing, the process it goes through to get that rule down—and
they’re constantly changing as things change. But yes, we wrote
all those procedures.
Wright: What aspect were
you involved with in the simulations to prepare the flight controllers?
Reeves: We all did the simulations.
That was your training, a big part of your training. You would have
classroom training where you’d have an instructor and you’d
go over different parts of the system. Then you would rehearse the mission
or different pieces of the mission by having simulations. We got to
spend some time in the simulators ourselves to go work with the various
systems when you could. Simulator time is a premium, and the crews have
priority and get most of the training. Then you’d have integrated
sims [simulations] where you’d have the crew in the simulator
and you’d have the flight control team in the Control Center,
then you’d do the actual rehearsals and you rehearsed different
parts of the mission. But yes, we all did that. Still do it today, it’s
still the greatest way to do it.
Wright: How well did your
training serve you, for instance, in Apollo 13?
Reeves: It was outstanding.
Flight Operations has always had the best training I've ever seen anywhere.
Even today the company I work for, USA [United Space Alliance], has
the Training Academy over here which trains all the flight controllers
and everybody now, and it’s just wonderful. It’s just some
of the best training you can get.
You have to have dedicated people in the training organization that
are there all the time, focusing on teaching. There’s always going
to be new people coming into the system and people leaving the system,
and you’ve got to have a mechanism for training them. You’ve
got to train to each mission. Each mission is unique and different,
and you’ve got to have people who can train you on that stuff.
My hat is off to the founders of this agency and these programs when
they recognized the difference between operations and engineering, and
they’ve always kept a separate engineering organization and a
separate operations organization. That is most important.
The other interesting thing about it was there was always a healthy
competition between the operations people who were engineers and the
engineering community, trying to outdo each other and be smarter than
the other person in your system. All engineers cannot do operations,
and all operations people cannot do engineering. They are two totally
distinct and different jobs, and a lot of people have never come to
grips with that.
There are a lot of operations people today even that believe they can
do the engineering job, and there’s a lot of engineering people
even today that believe they do the engineering on the systems and they
can do the operations. Well, it’s just not true. It’s absolutely
not true. Number one, the operations people that think they can do the
engineering job don’t even understand what the engineering job
really is, and the detail engineering that has to be done. The engineering
people that think they can do operations have no clue what it takes
to operate the integrated systems, and operate in a real-time environment.
Engineers in engineering work do a totally different time schedule,
time-frame.
When you launch one of these vehicles, there is a finite amount of time
when that vehicle has to be back on the ground, in Apollo it was a 7-
or 10-day mission. Today, Shuttle missions are 12 to 14 days, whatever.
You know when it lifts off, it’s going to be back on the ground
in 7 to 14 days, whatever the mission is, and you try to accomplish
everything in that 7 to 14 days and handle any contingency that comes
up. You can’t think like an engineer in that environment.
When I later became a flight director in Shuttle, one of our jobs was—and
we’ll talk about this probably in a different session—one
of our jobs was to train. We’d have training sims where there
would be new, young flight controllers coming in and you would have
training sims where you would train. You’d have an experienced
flight director on with a lot of new people in different system disciplines,
and you’re helping train them and then you certify them. Well,
in my career I have had, on occasion—fortunately not too many
times—but I've on occasion had to not certify a flight controller
because they just cannot operate in a real-time environment. I’d
have to tell them, “You’re a fine engineer. You’ve
got a wonderful career ahead of you, but you’re not going to cut
it in operations. You just cannot function in a real-time environment.”
And that’s true. There are people that just can’t do that.
Wright: I’m sure it
helped, the fact that you’ve had both those backgrounds, in being
able to help make that decision.
Reeves: I always knew that
to some extent, but I really, really didn’t see the difference
until I left NASA. I retired from NASA in 2001 and I spent almost my
entire career in operations. When I left NASA in 2001, I went over to
United Space Alliance. I went into Orbiter. I was the Deputy Associate
Program Manager for Orbiter as my first job at USA, which is an engineering
organization to take care of the Orbiter. It was a shock. I found out
that there were people worrying about things that I didn't even know
people worried about, and you get down to talking to these engineers
that are detail experts, not on a system but on a piece.
You have an engineer who is an M&P person, Materials and Properties
person, that understands metals and ceramics and tiles and the properties
of the materials. It’s got nothing to do with the operations.
These guys are detail experts in the real science of how this hardware
is made. You’ve got mechanical engineers that are just experts
on fasteners and screws and bolts and washers. In the operations world,
you don’t worry about that stuff. In the operations world, you
worry about an integrated system and how it operates and all of the
what-ifs and alternate ways of doing the job. It’s like you know
somebody built this car or this airplane that you’re flying, but
your job is to fly it. You don’t know a lot about whoever built
it, but in the engineering world, there’s some sharp people over
there. It’s just amazing, some of the experts you run into.
Wright: Do you find it so
different from when you entered the Apollo era?
Reeves: No. I just didn’t
realize it then. I look back on it and it’s always been there.
I just never realized it before. When I told you before, back in Apollo,
I always liked that healthy tension between engineering and operations,
where we were out trying to outdo each other. In the electrical power
system, over in engineering there was a subsystem manager in charge
of the power system, then he had working for him battery experts, and
relay experts, and wiring experts, and all this kind of stuff. Switches.
Detail people that understood all this stuff. We would use all of that
stuff, and we knew how to operate it, and we would try to learn as much
as we possibly could, but there’s no way.
You can’t write procedures and malfunction procedures and flight
rules, and execute them, and keep changing every mission, and work into
the new script, and learning what the whole mission is about, and training.
You can’t do all of that and stay current on the current engineering
state of technology, which is their job. We would rely on them. We were
constantly talking to them all the time about, “Hey, explain this
to me. How does this work? How does this work?” They’d be
tickled to death to tell you.
Even today, we still have the Mission Evaluation Room, the MER supports
the flight real-time, supports the flight control team. That’s
where all the real detail engineers are. They have access to even more
detail engineers and this huge network of detail engineering. If you
have a problem with a valve in one system or something not operating
properly, within minutes through that system and that network you can
get down to the person who put that valve together, and find out what
company built it, and who built it. It’s an amazing network, really
amazing.
Wright: You mentioned earlier
about Grumman building the LM. Did you have a lot of dealings with Grumman
personnel during those days?
Reeves: Yes, yes I did. I
got to know quite a few of the engineers, and we had a great relationship.
I went up to Long Island [New York] once, again, never having been anywhere,
as one of my first trips I went up to Long Island where they built the
LM, and went up there for a big battery test that we ran and got to
work with them. They were always coming down here, for meetings and
things, and we’d talk to them all the time on the telephone. Really,
really sharp people, real nice folks. I often wonder what happened to
all those people. I'm sure they moved on to other programs.
Wright: There was never a
lot of lead time with the LM, from what I've read. For instance, it
wasn’t on the schedule that the NASA management had wanted, so
that’s one of the reasons why Apollo 9 had to be a little delayed.
Did you find a lot of new information always coming in about your systems
as they were developing the LM?
Reeves: Yes, and we were
the cause of some of the changes in the system because we would operate
the system, we would see how it operated, and we would uncover problems
during a flight. You’d see something not operating correctly,
then you’d get with the engineers at Grumman after the flight
and you’d say, “Hey, this is not doing what it was designed
to do, and it’s not doing what it did in test,” and so everybody
would go analyze it and then you’d figure out if you needed to
make a design change to the system, but that’s the nature of this
business. We’re always doing that.
We’ve flown the Shuttle 125 times, and every time we fly it we
learn something new. People have talked about, is it an operational
system versus a flight test program? Well, it’s a flight test
program. The vehicle has never become operational. In Apollo, the vehicles
were never operational. It was a learning experience every time you
flew it. Apollo was just so different than anything else I've ever done
because you were doing everything for the first time and it was so new.
You were going to a different heavenly body.
Even as fascinating as it was—and I don't know if this is just
my nature, or the nature of the beast, or whatever—but even as
fascinating as it is, toward the end it got to be the same old same
old. Even though the missions were all a little different, and to the
geologists it was just heaven on Earth to them, but to some of us that
had sat in on all of the Apollo missions, they all started looking alike.
You launched. Three days later usually you’re landing on the Moon.
That’s all great and exciting and wonderful, and now you spend
two or three days on the Moon. Then you come back. One mission started
looking like every other mission. We used to talk about this on the
console. We’d sit there and think, “Here we are, sitting
here flying people to the Moon, and why is it getting mundane?”
It’s just something I've always observed, is that when you quit
learning, you die. I mean, when you quit growing, you die. I've always
noticed, somewhere in the five to seven-year time-frame, it’s
time to do something different because you just have to go get into
something different and do something different.
Shuttle has lasted for 30-some odd years. Every flight is so different,
but even it gets that way. I look at my own career. I was a flight controller
in Apollo from 1967 till the program ended in ‘72. So there’s
your five years, and by the time it was coming to an end, I was really
starting to think about, “It’s time to go do something different.”
Now, Apollo ended abruptly. I don’t remember exactly how it happened.
We all remember things differently, but I remember very little talk
about Apollo ending. We all knew it was a finite program. We knew it
was going on out to two more flights beyond where it actually ended.
But it was almost like coming to work one Monday and finding out, “Hey,
the program’s over. They just cancelled the last two flights and
the program is over.” It really ended abruptly. I can’t
say that I was sad, because I was ready to do something different. I
didn’t know what. I've been so naïve my entire life. I've
never had a career plan my entire life, and I just seem to fall in from
one good deal into another good deal, and I always have.
Wright: Maybe because you’re
open for opportunity.
Reeves: Well, I don't know.
I guess. It’s a lot of luck. I just have lucked out and been in
some fascinating things. I guess anything is what you make it.
Wright: Did you ever make
it down for a launch?
Reeves: Not in Apollo, no.
I never saw a Saturn; I was always here during launch. I was with NASA
for 34 years, and in my 34 years I saw one launch and it was Shuttle
launch. Since I've been with USA now, I have a console in the firing
room and I go down for every launch. I've even lost count of how many
I've seen now. But yes, I would have loved to have seen a Saturn launch,
but never got to.
Wright: You mentioned about
so many of the flights having so many similarities. But were there a
lot of differences from one mission to another in the LM?
Reeves: Yes, there were some
changes over time. We changed the LM to what they call the Extended
LM, where they increased the hover time and increased the stay time,
and we added an extra battery to the vehicle so we could stay on the
Moon longer. We modified the systems and added that capability to it.
Then later, we added the [Lunar] Rover, the little car that we’d
take up there, and we had to put that on the vehicle and figure out
a way to deploy it. And the science experiments that we carried, every
time were always different. Of course, the crews were always different.
That was the biggest thing that was different was getting to deal with
the different personalities, and that was fun, a great bunch of people.
Wright: Any stories come
to mind that you can share?
Reeves: There’s lots
of stories. Lots and lots of stories. I remember one story I've told
several times. I remember prior to Apollo 11, we were over in Building
45—I think it was in Building 45—and we were having a flight
rule review, trying to finalize the flight rules. In testing, they had
uncovered a problem with the landing radar on the Lunar Module. There
was a big debate between the people who made the landing radar and the
other folks about how it would operate, and in testing they had uncovered
some problems. They were trying to write a rule that said if the computer
on the LM, which wasn’t much of a computer, but if the computer
on the LM wasn’t accepting landing radar data by 60,000 feet above
the Moon, then it would be an abort because you wouldn’t have
the landing radar to tell you how high above the Moon you were.
They debated it for hours. It was a big room full of people. I was in
the room. I don’t even know why, but I was in the room. Up at
the head table was Neil [A.] Armstrong and Aldrin and Gene [Eugene F.]
Kranz and I don't remember who else. After a big long debate, they finally
say, “Okay, that’s the rule, everybody agrees. If it’s
not accepting data by 60,000 feet, it’s abort.” Nobody said
anything, and Neil was sitting at the end of the table with his hand
on his head, and his head was down, and he was shaking his head. I think
it was Kranz, looked over at him and said, “What’s the matter,
Neil? You don’t agree with that rule?” Neil looked up and
he says, “You must think I'm going to land with the window shades
down.” It was funny. You got the impression from him that he was
going to land no matter what.
What came out of that was a very interesting thing that the flight dynamics
people did. They actually came up with a modification to the trajectory
so that as the LM came down—because there was no point of reference
on the Moon. You look out the window and you see the rock, you don’t
know if it’s as big as a house or if it’s just a pebble.
You can’t judge any distance, so they shaped the trajectory to
where as the LM pitched over and as it came down, you could see the
shadow of the LM on the Moon. Then, as you came down, you just flew
the shadow, so you could tell where you were with respect to the ground
by where the shadow was. It was very clever, and it came out of all
that stuff.
But we used to have just one comical thing after another with Pete [Charles
C.] Conrad—Pete Conrad was just a stitch. He was more fun to work
with, and when they put him and Al [Alan L.] Bean together on a flight,
it was just amazing. I can’t remember any specifics right now,
but I just remember how much fun it was listening to those two guys
and some of the things that happened.
Wright: One thing, when you
were talking earlier about being in the room and not missing anything,
the thought for you that the electrical system is, of course, what powers
that LM to get where it needs to go, and to know that Pete Conrad and
Al Bean made that pinpoint landing for Apollo 12 had to be fun to listen
to for you.
Reeves: Yes, it was. Those
of us that worked the power system always—everybody likes to think
their system is better than anybody else’s. But the beauty of
the power system was it was the only system on the vehicle that interfaced
with everything on the vehicle. Nothing on the vehicle worked that didn't
get power, and so it was fun.
Wright: That’s what
made me think of asking about the—because if one thing got changed,
it had to impact your system, whether the weight was increased or decreased.
Reeves: Yes, and we were
just constantly going around, talking to all the other system engineers
about their system and trying to learn as much as we could about everything.
We put timelines together by hand where we would take the checklist
and the flight plan, and we would interpret every single switch throw
as a change in power level. We would put together these power profiles,
hand-computed, because the batteries were the only power system you
had, and you only have a finite amount of power in a battery, so you
had to know how long they would last. We had to know every minute of
the mission what the power levels were, and as they changed we’d
recomputed the power. We knew how much power it would take, so we knew
how long the batteries would last. Later in Apollo, as computers were
getting more and more en vogue, we developed with the Mission Planning
and Analysis Division a computer program to model the power system,
and we could input the checklist and flight plan into this model and
it would compute it for you. We built all that stuff and we developed
it from our old hand calculations, so we helped design the computer
program and then developed that capability. So technology was changing
right along and we were adapting to it as we could. Whenever something
new would come along, we’d jump on it.
Wright: As well as you knew
that system, did you have any hesitation when, after Armstrong and Aldrin
got back into the LM, did you have any hesitation that that LM was going
to ascend the way it needed to?
Reeves: Well, that was a
tense moment. Everybody, especially those of us that knew the vehicle,
you knew everything had to work.
Wright: It had sat there
for a while?
Reeves: Yes, and it had never
been done before. You can test and simulate all you want, but until
you actually do it, you don’t know. It’s like the first
[Space] Shuttle flight. The first Shuttle flight, there was no test
ever for the Shuttle system. The first time that vehicle every left
the pad, it was manned. In Apollo, we launched several unmanned test
flights with every phase of it. We had the luxury of doing that. You
couldn’t do that in Shuttle. We flew two or three unmanned, low-Earth
orbit LM test flights. Then we flew some manned low-Earth orbit test
flights before we ever went to the Moon.
Wright: I was going to ask
you if you had any memories or anything you’d like to share about
Apollo 9 and 10. They sometimes seem to be the unsung heroes.
Reeves: I've heard lots of
stories about that, and they don’t jive with the way I remember
it. In fact, I read something just recently about there was some political
motivation to why Apollo 10 didn’t land versus [Apollo] 11, and
that’s not the way I remember it. The LM had a severe weight program,
like all vehicles do. Constellation today, you read all about it, it’s
got weight problems. Well, all new vehicles have weight problems.
The LM had a severe weight problem, and we went through a major weight
reduction program where they took weight out everywhere they could.
They shaved metal off of things, they took boxes, systems off the vehicle,
anything they could to get the weight down on that vehicle. The LM that
flew on Apollo 10, was the last vehicle that had not been through the
weight reduction program. The vehicle on Apollo 11 was the first reduced-weight
vehicle. Apollo 10’s LM could not land. It was overweight. There
was no way it could land, and so they already had it built and they
had the mission design and everything else, and then they said, “Well,
let’s just do a full dress rehearsal. We can get a lot of value
out of this by doing everything but land.” Because there were
a lot of things we had never done before. Apollo 8 went to the Moon,
but it was just a Command Module. There wasn’t any LM.
Wright: That was with the
full dress of the LM and the space walk, [with] Rusty [Russell L] Schweickart
and also [David R.] Scott.
Reeves: Yes, but that was
Earth orbit, wasn’t it?
Wright: Yes, it was still
low-Earth orbit, yes.
Reeves: Yes, yes, that was
Earth orbit. But Apollo 10, they said, “Hey, we can do a full
dress rehearsal. We’ve never separated the LM and the Command
Module and done a rendezvous in lunar orbit. We have never abort staged
the LM. We’ve never flown the ascent stage by itself with a crew
and back to dock with a crew. We could do all of this stuff and get
a lot of value out of it in one mission without exposing you to the
risk of landing, even though we couldn’t land.” It was very,
very, very good use of a lot of good hardware, so they put together
the Apollo 10 mission and said, “We’ll go do that.”
So they flew to the Moon, got in lunar orbit, and then they separated
and they flew down to within 60,000 feet of the Moon and abort staged
the vehicle and came back.
That was a hairy moment because when they abort staged the vehicle,
where they separate the ascent and descent stage, while the engine was
burning, the vehicle did a 180-degree maneuver unexpected, and you heard
the crew go, “Whoa, what’s going on?” Everybody saw
on the telemetry, saw the vehicle turn around and you thought, “Holy
smokes!” Well, it turned out there was a switch out of position.
There was a rendezvous radar antenna on the front of the LM, and at
the time they abort staged, the Command Module was behind the LM catching
up with it in orbit, and because the switch was in the wrong position,
when it staged it told the computer to have the rendezvous radar lock
onto the transponder on the Command Module—which was behind them
at that time. So it turned around so it could see it. It was just doing
what it was supposed to do, but just nobody expected it to happen. You
always have surprises. That’s what makes this great.
Wright: I guess that’s
what keeps you on your toes there.
Reeves: Yes. That’s
what makes this fun.
Wright: You talked about
the simulations a while ago, and the training. I know that there’s
sometimes practical jokes played to create some levity of what was going
on. Were you ever the target of one of those, or even the instigator?
Reeves: No, no. I don’t
remember any practical jokes played on me, and I didn’t play any
on anybody else. I was always pretty serious about it, and I don’t
remember ever being the brunt of one of those jokes. In fact, right
now I remember there were some, but I can’t remember just offhand
any of them.
Wright: When did you learn
about the Shuttle coming online?
Reeves: Well, toward the
end of Apollo and around the [19]70-71 time frame, they were already
talking about this thing called Shuttle. They would select some of us
to go off and be on these Tiger Teams to start writing the requirements
for a system for this thing called the Shuttle. I spent some time on
some of those Tiger Teams. They would say, “Hey, for the power
system of the Shuttle—” At that time, they didn’t
even know what the power system was going to be, and was it going to
be all batteries? Was it going to be fuel cells? Was it going to be
a combination? Was it going to be nuclear? What should it be? So we’d
have these team meetings, and we were trying to define the requirements
for this thing. We were already starting to talk about it. We had these
concepts of what a Shuttle was and what it was supposed to do, but it
was the very early, early, early design days.
But then when Apollo ended, we were faced with the gap that they talk
about today with the end of Shuttle and the start of Constellation.
They’re talking about a five-year gap, six-year gap, whatever
the number is nowadays. Same thing was happening back then. When Apollo
ended in ‘72, the first flight of Shuttle was supposed to be ’79
or ‘80. That was the projected first flight. Turns out it didn’t
fly until ‘81, but at that time it was about ‘79, I think.
So you were looking at about an eight-year gap, worse than what they’re
talking about today, and everybody was really worried about that.
They threw together a couple of programs called Apollo-Soyuz and Skylab
to fill the gap with using some old Apollo hardware, leftover Apollo
hardware, to do something very useful and to keep people employed and
keep the operations team together to help plug the gap. So these two
programs sprung up and helped fill that gap, but that took care of the
Command Module people and it took care of some of the other people on
Skylab and some of the Saturn folks. But us LM folks, we didn’t
have a job basically. I didn’t even think about it. I figured,
“Well, I'll do something.”
Gene Kranz was head of Flight Control Division at the time, and he had
put together a little Tiger Team of people to go out and try to figure
out some way to keep the team together and some other things that they
could do. A friend of mine was on that Tiger Team, and he told me one
day that they had discovered this aircraft program, Earth Resources
Aircraft Program, that was over under Science and Applications directorate
at the time. He said it’s a neat little program, it’s got
several airplanes that do Earth resources work, and he said they’ve
got their own budget and everything. It was something that they could
put a bunch of people into and make something out of, and people could
learn a lot and it would keep the team together for many years. He said,
“This is right down your alley.” In particular, one part
of the program was the high altitude airplanes, the WB-57F, which flies
real high. He said, “That in particular is one that you ought
to think about.” I got whatever information I could about it,
and it sounded pretty intriguing.
Then this Tiger Team convinced Gene Kranz, “Here’s something
viable, here’s something you can do something with.” He
jumped on it and he went to the Center Director and he got the program
moved from Science and Applications Directorate over to [Flight] Operations
[Directorate] as an operational program. Then he put a letter out and
he says, “We’ve got this new program coming into the Flight
Ops [Operations], and they’re looking for volunteers to staff
up that program.” One of the jobs they were staffing was called
a mission manager, and there were mission management jobs on the B-57,
the C-130, the P-3, and some helicopters. I responded to the letter
and said, “I'm looking for a job anyway and would like to stay
in operations, and I’d like to go for the mission manager job
on the B-57.” He had appointed Charlie [Charles S.] Harlan as
Head of the Aircraft Operations Branch. I think that’s what they
called it. It was a branch they formed under Flight Ops for this aircraft
program, and they put Charlie Harlan in charge of it.
They called me one day, Kranz and Harlan, and said, “Come over
to my office.” So I went over there and they said, “Hey,
we want to keep you here. We’d really like you to stay in Operations,
and we really think you’d be great in this aircraft program. We
only have one problem.” Gene told me this, he said, “We
only have one problem. The B-57 is a two-person aircraft, it’s
a tandem cockpit, pressure-suit operations. The mission manager flies
in the airplane and is an air crew member, and you don’t have
any aircraft experience, and that kind of bothers us.”
I said, “Well, Gene, people that fly in airplanes weren’t
born in them.” I'll never forget it. Gene just closed the book.
He said, “That’s it. That’s all I wanted to hear,”
and he says, “You’re in.” So I went over to the program.
Then we had our own training program. We went through Air Force Training
Schools. I went to Kirtland Air Force Base in Albuquerque [New Mexico]
for FTD [Flight Test Division] school on the airplane itself, and I
went through pressure suit school at Tyndall Air Force Base [Panama
City, Florida]. I went through arctic survival and water survival, jungle
survival at various schools that the military had set up, and we went
through all these. Since you’re a navigator in the backseat—and
I was a backseater, not a pilot—we went to Nav [Navigation] school
and learned how to navigate.
Wright: You adapted just
fine?
Reeves: Yes, yes. It was
great. That was just so much fun I couldn’t believe it. We went
out to Tyndall and got fitted for suits and went through suit test and
suit training, then went out and flew in the airplane.
Wright: Amazing. Well, you
have to tell us some details about the differences of arctic survival,
tropical survival, water survival. Tell us about some of those events;
anything specific about going through those? They sound pretty memorable
to me.
Reeves: Well, the FTD school
on the airplane at Kirtland, up until that point, the airplane belonged
to the Air Force. They only had one airplane. They had a science package
that had all the cameras and sensors in it that fit on the bomb bay
of the airplane. Whenever they would get ready for a mission, they would
call the Air Force, the 58th Weather Squadron, and have an air crew
fly the plane to Ellington here and they’d fit the pallet on it,
and then they’d go fly the missions.
Well, all of that was changing at that time, where they actually got
one of the airplanes transferred to NASA, and then they wanted NASA
air crews to fly it. They wanted NASA pilots and they wanted NASA mission
managers to fly the backseat. Since Kirtland was the home base for the
airplane, they sent us out to Kirtland to learn the airplane, the systems
on the airplane and how to fly the airplane and all that. It was interesting.
That airplane had a very bad characteristic called mach tuck. It was
severely air speed limited, and if you exceeded critical Mach number
on the airplane, you’d lose control of it and it’d go into
a dive, and it would go into structural flutter and tear itself apart.
An air crew based at Kirtland had just lost one to mach tuck and it
had crashed. The day I showed up for FTD school they were bringing the
pieces of the airplane into the hangar and had them spread out on the
hangar floor, and they were in the middle of the investigation trying
to put the airplane back together. It was pretty much of an eye opener
and you said, “Hmm.” I hadn’t even flown in it at
that time, and here are just pieces of this thing. It killed the crew;
neither one of the crew members got out. They were doing mach tuck testing,
and they intentionally put it into tuck and they lost control of it,
and it got them.
That school was a several-week school, and you went through all kinds
of systems training on the airplane. Then there’s a water survival
school down at Homestead Air Force Base in Florida, where all of the
Air Force, new air crew members, go through water survival in case you
have to eject out over water or something.
Wright: So you just became
part of that training?
Reeves: Yes, they just got
us slots into a class down there, and we went down there and joined
right up with them and went through water survival. I’d pay to
go see that stuff. It was so much fun. They’d take you out and
drag you through the water behind a boat, then they’d put you
on a parasail and take you up real high and you’d get to fall
in the ocean and a helicopter would come pick you up, after you bobbed
around in the ocean a while in a rubber raft. Then you’d go through
jungle survival in Panama, which was the same survival school the astronauts
went through, in case you ever went down in the jungle, you’d
know how to survive until somebody found you. Then one of our missions
was flying way up north of the Arctic Circle out of Alaska, and we were
way out over the pack ice so we had to go through arctic survival training
in case you ever went down up there.
Then I came back here and got a flight in the airplane. The first couple
of flights were what they call non-pressure flights where you didn’t
wear the pressure suit, you just wore a flight suit. You’d stay
low altitude and you’d just fly around the area. You’d get
used to the airplane. I flew a few of those. Then you suited up and
went for the pressure flight.
I remember the first pressure flight because your depth perception,
your whole perception of distances is screwed up. I can’t imagine
how much trouble astronauts have, because we were flying over 60,000
feet. We’d get high enough to where the sky is black and you could
see the curvature of the Earth, and you can see the horizon. You can
see about 400 miles in any direction. We took off out of Ellington,
we climbed up to altitude, and we were flying across this area and I
was looking out the window thinking, “Where’s Houston?”
I'm looking out, “Where’s Houston?” Then, “Oh,
there it is!” There’s Houston, there’s Galveston,
and everything is real close together and right underneath you because
you’re so high. It just changes the way you think about things.
When I first got in it was at the same time that they actually moved
one of the planes here and we had one here. Then later, we added another
one. So NASA had two of them here, and then the 58th Weather Squadron
was still doing a mission for what used to be the Atomic Energy Commission
and later became ERDA [United States Energy Research and Development
Administration] and then several other agencies. Some of the work they
were doing was black work or secret work, and some of it was the first
theories about Freons depleting the ozone layer and all that stuff.
There was a group out at Sandia [National Laboratories, Albuquerque,
New Mexico] that had come up with these theories, and so they were sampling
air to try to verify these theories. They were using an airplane out
of the 58th Weather Squadron to do that, then the DoD [Department of
Defense] decommissioned the airplanes and did away with all of them
and sent them all to The Boneyard [aircraft storage and maintenance
facility], and the 58th went out of business.
Well, these agencies came to NASA and they said, “Hey, you guys
have air crews and maintenance crews and pressure suit people and everything,
and you fly out of two of these airplanes that belong to you. Could
you all pick up this mission for us?” They had the budget for
it and everything. They said, “Could you all continue to do this
mission for us?” We said, “Sure, but if you’ll give
us another airplane that’s got the right equipment on it.”
They did, and they gave us a third airplane that had all of the sensors
on it that they maintained. So we would fly that plane. There was a
regularly scheduled mission that was a 14-day mission where we would
sample the air at 50,000, 55,000, 60,000, and 63,000 feet, between seventy-five
degrees north latitude and ten degrees south latitude. We’d do
the southern part out of Howard Air Force Base in Panama Canal Zone.
We’d do part of it out of Ellington. We’d do the northern
end out of Anchorage, Alaska, out of Elmendorf [Air Force Base], then
we would do a couple legs on our way to Elmendorf. We’d spend
one night in McChord [Air Force Base], in Seattle [Washington]. They’d
want you to fly that mission and finish the mission as fast as you could
from the time of the first flight to the last flight, and they’d
do that three times a year. The whole purpose of it was to provide a
database, cross-sectional air sampling of the atmosphere at three distinct
times through the year so they could track the ozone and Freons and
all this other stuff.
Then we also went to some other training that I can’t talk about
that was part of DoD, for the black, secret work. We picked up that
mission too, and we did that for them. We had three airplanes going.
Then when Skylab flew, we had the same camera systems on the airplane
that Skylab had onboard, and so whenever Skylab would make a pass over
the US, we would be underneath it and we would take data from the same
area that Skylab was looking at. Then we would have several of the other
airplanes below us taking data. We did what they call multistage sampling,
where you would have imagery of the same spot from many different altitudes
so you could calibrate the sensors on Skylab from our data. Then we
got into all kinds of Earth resources work, doing crop surveys. We would
put missions together where you’d stage the airplane out of some
Air Force base somewhere in the country, you’d get a whole bunch
of test sites in one area, you’d go move the airplane there for
a week or two, fly out, fly all your sites, and come back.
Wright: Were you always assigned
with the same pilot, or did you work with different ones?
Reeves: No. We had about
six or eight pilots that were checked out in the airplane, and so you’d
draw a different pilot. There was no telling who you’d be with
that day. There were five of us that flew the backseat, that shared
the duties. You’d stay at altitude about five to five and a half
hours. There was a rule that we inherited from the military that if
you fly over five and a half hours in the pressure suits, you can’t
fly again for thirty hours. It’s a physiological thing. Whenever
we’d go on deployments, we’d take two crews and we’d
alternate flying days. If you flew one day, you couldn’t fly the
next day. You’d have to stay down. We found out you couldn’t
even do that for very many cycles. You could fly about three cycles
in a row, where you’d fly every other day for three times, then
you were just shot. You’d have to stand down. Never did really
know why.
Wright: Did you fly often
during that time period that you were working there?
Reeves: Yes, we flew a lot.
I was in the program from ’73 to ’79, and I flew over 1,200
hours in the airplane. So you got a lot of good flying in.
Wright: Is there a mission
or two that’s more memorable than the others?
Reeves: Well, later in the
program there were seven or eight federal agencies in Alaska that pooled
their budgets, and they were trying to photo-document the state of Alaska
before it started getting all messed up with civilization. They wanted
a baseline of what was there, and so we would go up there six weeks
every summer and stage out of Elmendorf. We had the NASA U-2 staging
out of Fairbanks and we were staging out of Elmendorf in Anchorage,
and we were photo mapping the entire state of Alaska. We’d fly
wherever the weather would let us fly. We did that every summer. That
was fun.
Wright: Did you find a lot
of changes every time you went back, or was it a lot the same?
Reeves: Nothing that we could
notice from the airplane. They were looking at detail stuff. The scientists,
or what we call the principle investigators, would put together the
projects that they wanted, and we would help them write the projects.
We knew the capability of the airplane, and they knew what they wanted
to do scientifically, and we’d get together and we’d figure
out how to do it. This was all very valuable training because it paid
off when we got to Shuttle.
We were learning how to outfit sensors on an airplane and adapt it to
multiple missions, which is what you do with the Shuttle. We were learning
how to work with scientists and put the operational end of it to get
with the science people and learn how to work together. It really paid
off. We did a lot of the pioneering stuff that people don't even think
about anymore today. We did all the original development work for the
theories for Landsat satellite that eventually replaced what we were
doing with the satellite. That came later.
We did a bunch of early tests on communication via laser from the airplane
to the ground. We did all of this pioneering work on ozone depletion
because of Freons. We were the only ones in the world providing that
data and verifying what was going on. Some of the other black work was
fascinating.
I enjoyed going down to Panama and flying out of there, enjoyed going
to Alaska. Out of Panama, we’d fly the southern leg. We’d
fly out of Howard and go down the west coast of South America and fly
straight down, we’d make our turn back to the north and our climb
at Lima, Peru, and then we’d come back north. That was beautiful.
You’d be flying right straight down the coast of South America,
and you’d see as you were going south the Andes Mountain Range
on your left and the ocean on your right. It was beautiful.
Wright: You helped manage
and implement a major redesign of the sensor systems, of the universal
power system.
Reeves: Yes. When we first
got the airplane, it was fitted with just a pallet that would go on
the bottom of the airplane that was just one big pallet that had fixed
camera positions and a scanner in it, so you were limited in what you
could do. We designed and developed what’s called a universal
pallet system, where we segmented the bomb bay into four sections and
we had four pallets. You could get a blank pallet, and a scientist could
develop his own sensor and put it in that pallet, and then we could
roll any combination of pallets under the airplane and just hook them
up and raise them up and fasten them to the bottom of the airplane.
We could vary the sensor complement for any mission based on what the
scientists were trying to get. It gave the airplane a lot more flexibility,
and the people that we could do missions for, and it turned out to be
a great thing. Again, it’s very similar to what we do in Shuttle.
You get this big payload bay and you just put different sensors in it,
and we learned a lot from what we were doing in those days and how to
do all of that.
Wright: It’s kind of
a long way from Jonesboro, Arkansas, wasn’t it?
Reeves: That’s a long
way from Jonesboro, Arkansas. A long way. I still am amazed.
Wright: Yes, that’s
a lot to be able to see from up there, from down to the tip of South
America. Did you go further east or west?
Reeves: No, no. The only
other really far off place, we went to the Azores once, which is a little
island about 600 miles off the coast of Spain. The principal investigators
were studying weather, and they wanted to go to the Azores in February.
We kept telling them, “You don’t want to go to the Azores
in February; it’s the worst weather in the world.” They
said, “No, that’s what we want to study.” So we told
them, “Well, this airplane is kind of fragile. It’s long
wings and kind of gangly on the ground, but it’s a beautiful flying
airplane. But it can’t take a lot of weather.”
So we flew from Houston to Langley Air Force Base in [Hampton] Virginia
because we couldn't make it to the Azores from Houston. We didn’t
have enough gas, and we only had one-way gas, to get from Langley to
the Azores. We couldn’t make it to Spain. We had to get to this
10 by 20-mile island, and we had to fly at pressure, at altitude, in
order to be able to even get there with the gas we had. It doesn’t
take as much gas when you’re up high. So we said, “We’ll
go to Langley. We’re going to stay at Langley until we get a good
weather forecast so we can go, and if we can’t get any good weather,
we’re not going.” They said okay, so we flew to Langley.
The very next day, we got up and checked the weather and they said,
“Go, good weather!” We took off and we flew to the Azores.
Of course, by the time we got there, the weather had changed and the
winds were way out of limits, and we landed in horrible winds. We rolled
the airplane straight into the hangar, shut the doors, and we were stranded
there for 10 days. The weather got so bad we couldn’t fly. After
about six or seven days, I told them, “The first good weather
day we get where we can get that airplane out of the hangar and take
off, we’re going home.” We were there for 10 days before
we got a break in the weather, and we rolled it out and we headed back.
We never flew the mission. It was pretty nasty weather.
Wright: Yes, that’s
a long way from home to be stuck with the weather, that’s for
sure. You shared with us earlier that your first encounter with that
type of plane was the one that came back in pieces. Did you have any
close calls while you were working on these assignments?
Reeves: I just had one. We
had two or three in the airplane while I was in there with other crews,
but I had one and that was down over South America. We were going south,
and we were at altitude. We were at 60,000 feet. We had made a maneuver.
The air is so thin at that altitude that you can’t make quick
maneuvers, it causes problems, and we made a maneuver and we lost control
of the airplane. It went into this tuck, it was on its way into tuck,
and the air speed was building up and we were losing altitude. It was
out of control for a little bit, and I had cleared my lap in the back
and I was getting real close to getting ready to eject. Because in training,
they had told us from the onset of tuck until the airplane starts coming
apart is 13 seconds, so you get 13 seconds to make a decision.
When you’re in the airplane, you’re in pressure suits and
you’re hot miked to each other, and you can hear each other breathing
and you can talk. I could hear the pilot had his hands full; in fact,
he was hollering that the thing was running away, and I could hear him
huffing and puffing and fighting the airplane. You don’t have
any controls in the backseat. I was just about to the point of asking
the pilot, “Are you getting control of this airplane?” and
if he didn’t give me the right answer, I was gone. I was leaving.
About the time I was about to ask him, I started feeling the airplane
squat. I could feel G’s [gravity] building up and I could tell
that he was starting to recover. We had lost, I don't know how much
altitude—I don’t remember, but 10,000 or 15,000 feet we
lost in just a matter of seconds. It squatted, and then he overcorrected
and it lofted and it did kind of a zero G thing and it went into another
squat. We went through about three or four of those and he finally got
it leveled off and got control of it again. I remember the Air Traffic
Control Center came on and was hollering in the radio, “Do you
have a problem? Are you in trouble?” Because we didn’t have
clearance to come down, and he saw us on radar, saw us descend and saw
us descend rapidly. They were saying, “Are you okay, do you have
a problem, do we need to notify anybody or anything?” We said
no, we’d got it now, so we climbed back up and went ahead and
finished the mission, then came back.
Then I was in Alaska once, and we had an explosion onboard the airplane.
We knew something blew, but we didn't know what it was. Everything was
working. The pilot and I talked about it, and we were doing what’s
called a vertical profile, where you’re sampling air every 10,000
feet, started at 10 and you sample every 10,000 feet up to 63,000 feet.
We had just finished 30,000 feet, I think, and we were in the climb
to 40,000 when something blew up on the airplane, because we felt the
whole airplane shake and we heard this big, “Whoomp!” We
thought, “What in the world was that?” We put it through
all kinds of maneuvers and tested the airplane. Everything worked fine,
all the systems were working. We couldn’t figure out what in the
world that was.
So we talked it over, and I told him, I said, “Well, let’s
go ahead and fly the 40,000, 50,000 foot samples, and that’ll
keep us from needing the pressure suits and getting over 50,000, and
it’ll also shorten the mission to where we can get back and land
while it’s still daylight, so we don’t have to land in the
dark.” I said, “Because if we had something like a tire
blow up or something like that, in the wheel well out there, I don’t
want to trip over something in the dark running away from this thing
at night.” He said, “That sounds like a good plan. We’ll
do that.” So we did that.
We went back and landed, an uneventful landing, and pulled the bomb
bay off of the airplane. Ball bearings went rolling everywhere, and
there was a big environmental canister in the payload bay that kept
a sensor warm, and it had a big door on the side of it and it was pressurized
and heated from the engines. The regulator had failed on this canister,
and it over-pressurized it and it blew the door open on the side of
it, and the door swung up and it hit a bunch of stuff and knocked a
bunch of ball bearings off of things, and broke a bunch of stuff, but
it didn’t affect the airplane’s flying ability. We were
grounded for several days while they flew parts up and got us going
again.
Wright: Good to be on the
ground though, wasn’t it?
Reeves: Yes, yes. But that,
it was just one fun flight after another. It was always something different.
Wright: Did you leave the
program or did the program close down?
Reeves: I left the program.
Like I said earlier, you do something five to seven years—and
I used to sit there in that airplane, especially when you’d gone
out on a mission and you had finished the data take, and you were then
just ferrying back to the base, a couple hours ferry flight where you’re
just boring a hole through the sky. I can remember sitting there in
the airplane, looking at the instrument panels, thinking, “Reeves,
what are you doing? You can’t do this the rest of your life. As
much fun as it is, you just cannot keep doing this. This is the same
instrument panel you’ve been looking at for the last five or six
years, and you’ve just got to go do something different.”
I was already in that frame of mind, and Shuttle was getting closer,
and I was sitting in the office one day at Ellington and the phone rang,
and it was George [W. S.] Abbey. I knew George real well, and he said
that they were coming up on the first flights of the Shuttle, and it
was getting closer, and he said, “You’ve been out there
having fun for all these years, flying airplanes and stuff,” and
he said, “We need some help back in operations on the RMS, the
Remote Manipulator System,” which is the robotic arm on the Shuttle,
which wasn’t supposed to fly until the second flight. But he said,
“We’re having some problems getting a team pulled together
and getting set up to support that system,” and he said, “How
would you like to come back and go back into flight control and help
get that set up?”
I told him, “You know, it’s funny you should mention that.
I've just been sitting here scratching my head, wondering what I was
going to do when I grew up, and that sounds really interesting.”
I took him up on it, and I came back and that's when I left the Aircraft
Program. They’re still flying the airplane out at Ellington. There’s
two of them still out there; it’s the only two left in the world
that are still flying, but they’re still flying missions and still
doing it.
Wright: Haven’t gone
and volunteered to take another ride?
Reeves: No, I’d do
it in a heartbeat, but I've hung it up. That’s behind me. You
finally get to that point where you get over it.
Wright: I guess maybe you
look at maps a different way now, because you’ve seen so much
from above compared to what you see.
Reeves: Yes, you look at
everything differently. I've often thought, to me, astronauts must have
a hard time, because once you’ve flown in space, it’s how
do you top this? For the rest of their lives, there’s nothing
that’ll top it, I don’t think, and that is such a unique
experience. We weren’t astronauts by any stretch. We got close,
but we didn't get there. We didn’t get zero G, but we did get
high enough where you look out the window and it’s sort of the
same view you see out the Shuttle.
Wright: That’s amazing.
It might be a good time to stop, and we can pick up with Shuttle when
you come back again.
