Just FYI: As of 4 or 5 years ago, Blackbird Airpark in Palmdale CA (in sight of the Palmdale Skunkworks) had an SR, an A-12, a drone, a 1 m stainless wind tunnel SR model, an engine (with a big chip out of the compressor), an early U-2, an F-17, all almost kick the tires close, as well as many other things. When I was there the girt shop was manned by an ex-RSO ("Rear Seat Occupant" according to the pilots manual.) Highly recommend the book: "Flying the SR-71 Blackbird: In the Cockpit on a Secret Operational Mission" Which details everything from meal the night before to suiting up, all the cockpit and ground pre-flight, including what switches when and why. After reading this, you could almost take-off and fly the SR yourself.
