And what about all the Naval Aviators who flew the Shuttle? Why not display it at Pensacola then at the world class NMNA?
Yes it's true that the without the USAF funding at the beginning, the shuttle program was at a risk of getting canceled. BUT, do not forget about the fact that the USAF really did not want to be involved at all! In 1969 the USAF MOL (Manned Orbiting Laboratory space station) which was actually a manned spy platform, was cancelled. The new spy satelites coming on line could do the job, and once data link transmission of real time photos matured, and replaced the need to parachute film back to earth, they came into there own. The USAF did not want or need the shuttle, they wanted to spend the money on other programs, but in the end they bowed to pressure.
There was a big drawback to this. NASA ended up with a vehicle that was bigger, and more complex then they ever planned on. The Air Force dictated the design basically. They insisted on the 15 by 60 foot cargo bay in order to accomodate their biggest spy satelites coming online. They also insisted on launching in a polar orbit from VAFB, with the option to just do one orbit to launch a satelite or perhaps grab an enemy one and then land. Problem is that unlike launching from KSC in Florida due easterly, launching from CA to the south poses a problem. When you do one orbit your landing site has moved. That resulted in the shuttle requiring a large crossrange capability of at least 1500 miles. This results in a delta wing configuration, with higher re-entry speeds and the requirement for a more robust TPS requirement, the famous tiles.
This all resulted in the vehicle we have relied on for the past 30 years. The large size dictated that it had to be a side mount with the problematic tiles which gave it the "glass spaceship" nickname. As we know the history, this configuration has resulted in the loss of two of them. Ice/debris from the ET damaging tiles, and the segmented strap on SRB's with the burn through. If you research the early shuttle history, you will see they originally planned on a much smaller, lighter and cheaper vehicle with an almost X-15 like shape that could be mounted to the top of a rocket, and would have had much lower re-entry speeds. The result would have been a totally different vehicle and launcher that most likely would have negated the reasons behind what brought the two shuttle down.
The USAF involvement did not do the program any favors. Also don't forget the fact that after the loss of Challenger, the USAF took the opportunity to bail out of the program totally. There were a few NRO flights but most of the assets were launched on rockets. VAFB was scrapped and funding was cut.
If you want further evidence of the USAF attitude to the shuttle, I recommend the book 'Riding Rockets' by Mike Mullane. Mullane was an Air Force WSO on F-4's in Vietnam and was selected as a shuttle mission specialist in 1978. His second flight was an NRO mission and afterward the crew was invited to a private ceremony at the Pentagon for citations. Hoot Gibson was the CMD and he describes they white glove treatment they received from the Navy Admirals and staff when they were presented the awards. They then proceeded to the Air Force office to meet the General who would cite Mullane. You have to read his account to believe it. A very cool reception that was embarrasing after what they had just been greeted with. Mullane throughout his book uses more examples to illustrate how the Air Force was not a fan of manned space flight.
In any case that book was a great read and I highly recommend it for a real frank and humorous look inside the closed doors of the space program that the public doesn't see.
