The U.S. Air Force’s Manned Orbiting Laboratory (MOL) program
was always about three years away from its first launch due to insufficient
funding, and was eventually cancelled after only a single flight of a test
capsule in the Gemini-B configuration. It had become apparent to the Air Force
that MOL would essentially be duplicating the effort of what would become NASA’s
Skylab program, and that unmanned reconnaissance satellites had developed to
the point where manned presence in space was unnecessary for that purpose (ref.
5).
The seven youngest MOL pilots were accepted as NASA
astronauts, their disappointment in losing one space program growing into
delayed but glowing successes when they came to dominate the early Space
Shuttle era. But in 1967, another MOL physician with a degree in physics, a
background as an engineer and aspirations to spaceflight had already made similar
arrangements.
William Thornton was one of the self-motivated would-be
space travelers that space programs inevitably attract. After earning his
bachelor’s degree in physics in 1956 and serving in the Air Force as a
specialist in airborne electronic instrumentation, he returned to civilian life
to apply his engineering expertise to problems of monitoring clinical patients.
In 1961, halfway through medical school, he attended a space medicine symposium
in San Antonio, Texas, and came away determined to fly in space himself. In 1963, the newly-minted M.D. re-joined the
active duty Air Force as a captain and completed a rotating internship at the
Wilford Hall USAF Hospital at Lackland AFB and the primary flight surgeons’
course at Brooks AFB, both in San Antonio. It was then that he became involved
in space medicine research for MOL. His experience while in medical school,
where he developed capabilities for monitoring surgical patients under
anesthesia as well as the first on-line automatic ECG analysis, had obvious
application to the problem of remotely monitoring the health of astronauts in
space (refs. 3, 5 and 7). He also designed and developed the first mass
measuring device for measuring MOL astronauts' body "weight" in weightlessness (ref. 4), which was patented in 1971
(ref. 8).
This prototype body mass measurement device (BMMD) was produced for Capt. William Thornton at the Brooks AFB for in-flight measurements on MOL astronauts. |
Dr. Thornton serendipitously rescued his prototype BMMD from a discard pile at Brooks AFB, and arranged for it to be donated to Gumma University in Japan for teaching and research. |
Thornton told me (personal communication, 2012) that he had
gotten into the MOL program “to try to get a flight.” This might have been
conceivable in 1963, but by 1966 it was clear that MOL would not provide such
an opportunity. By then there were a dozen designated MOL pilots for the ten
available seats (and four more would be selected in 1967). If they were somehow
inadequate, the unofficial pilot-physician cadre, sponsored by the Air Force
Surgeon General, was poised to claim any openings. Given that the Surgeon
General’s protégées (see "A Jones for MOL #8: Shadow MOL Men (Part 1)") are so poorly reported in the accessible literature, it
is not impossible that other Air Force organizations were also considering
their own would-be astronaut corps, but proof is still absent. Indeed, twenty
years later, the Air Force, the Army, the Navy and the National Reconnaissance
Office all had cadres of as few as two or three to as many as thirty-one
specialists for Space Shuttle missions. Although the Shuttle provided many more flight opportunities than MOL could have done, only three of
these service members flew in space before such efforts were discontinued (ref.
5).
In 1966, Thornton contacted NASA about the upcoming second
recruitment of scientist-astronauts—having skipped the first such opportunity
in 1964 due to his age—and in an August letter, Slayton advised him to apply
under the relaxed constraints of the new recruitment. The application period
ran from late September into November 1966. Thornton was selected as a
scientist-astronaut by NASA in August 1967 (ref. 3).
Although he had left the Air Force and its MOL program, Thornton
stayed connected to it (ref. 3, 5 and 7). In 1968, as a civilian astronaut
trainee, NASA sent him to the Air Force for jet pilot training, a requirement
of all NASA astronauts at that time. Then, in 1972, he spent 56 days simulating
a Skylab space station mission with Robert Crippen and Karol Bobko, two of the
MOL pilots who had transferred to NASA in 1969. Later, his two Space Shuttle
missions were both commanded by MOL transferees: Richard Truly on STS-8 in
1983, and Robert Overmeyer on STS 51-B in 1985.
There are always would-be astronauts in and around any
space program. Even space programs with no usable hardware or practical
prospects attract would-be astronauts. A quixotic bid to resurrect the Gemini
project, “Americans in Orbit (AIO)-50,” surfaced briefly in 2008 and then
collapsed completely, but not before a two-person crew was “selected” and
visited nearby elementary schools giving inspirational speeches (ref. 1). In 2013, “Astronauts4Hire,” a non-profit
organization, is recruiting crewmembers to tend payloads on upcoming commercial
suborbital spaceflights as proxies for investigators who apparently cannot be bothered to
fly to the edge of space themselves alongside billionaires and
movie stars on sight-seeing junkets (ref. 2).
More realistically, in late 1964, Fred Kelly, a Navy flight
surgeon and aviator on loan to NASA, had petitioned Manned Spacecraft Center
director Robert Gilruth to fly a pilot-physician such as he on the planned
long-duration Gemini flight instead of one of the professional test-pilot
astronauts. Gilruth politely declined to
fly someone who had not been competitively selected (ref. 6).
Joseph Kerwin, himself a dual-designated Navy flight surgeon
and qualified jet pilot who had, in fact, been competitively selected in the first
scientist-astronaut class in June 1965 (the one which Thornton had
intentionally sat out due to his age), still could not accomplish what Kelly had
attempted. Kerwin has told the story of his first Monday morning astronaut
office meeting, after chief astronaut Alan Shepard introduced the new
astronauts to their senior colleagues, and then asked for a show of hands from
those pilots interested in upcoming Gemini flight assignments, followed
immediately by “put your hand down, Kerwin” (personal communication, ca. 2011).
Some, like Kerwin and Thornton, eventually made the next
step into orbit themselves; others, like Kelly, never did. But they all advanced
the cause of human understanding in spaceflight through their service and
contributions.
