What's so surprising is that this is supposedly using an SR-71 that was on outdoor display. The Museum of Flight in Seattle has one in much better condition.[1] It's on loan from the USAF, so the USAF could take it back if they needed it. There's another one at the US Air Force Museum in Dayton, and a third at the Smithsonian's annex in Chantilly, VA. All three of those have been stored indoors in good conditions, and were flown to their current location under their own power. Not abandoned outdoors on a pylon.

This sounds too much like a politically motivated decision.

If the US needed a hard to shoot down recon aircraft, converting a cruise missile to carry a recon package would probably be quicker. There's also the X-37B, the unmanned mini space shuttle the USAF has. The USAF launches one once in a while. It stays up for a year or so, and then comes back down and lands. There have been about eight flights. Seems to work fine. Once it was put into an orbit that grazed the atmosphere and went back out, to test if could do high-altitude recon if desired. It looks a lot like the original Space Shuttle, but it's much smaller, about the size of a small aircraft.
