Edwards Air Force Base, 1964

The first public Blackbird display was conducted at Edwards Air Force Base in September 1964. Lyndon Johnson announced the existence of the A-11, a 2,000-mph interceptor capable of flight at altitudes above 70,000 feet. A pair of YF-12As were flown down from Groom Lake to be displayed as A-11s at the event. 60-6936 posed for static shots and 60-6934 took off and performed flybys. They were still warm from the supersonic flight to Edwards when they were rolled into a hangar. The residual heat set off the sprinkler system in the hangar.

Mark Hickman ran across a set of photographs of the YF-12A display at the estate sale of General Dynamics executive Gordon E. MacDonald of St. Louis.

Lockheed SR-71A 61-7974 crewed by Gil Bertelson and Frank Stampf departed the October 31, 1981 Beale AFB airshow early in order to appear at two other airshows that day. According to Frank Stampf: "We departed Beale early that morning and did a short supersonic leg to Colorado Springs, where we did a flyby for the Air Force-Army game. We then went supersonic back to Beale and made two low passes to open the show. We then flew subsonic to California and did a low pass at Point Magu, then to March AFB where we did two low passes before landing and putting the airplane on static display for the weekend. To top it off, I left Beale on that trip as a captain on October 31, and returned to Beale as a major on November 1."

Edwards Air Force Base Open House, October 6, 1990

SR-71A, 61-7971 on static display in NASA markings at the October 6, 1990 Edwards AFB Open House. It was registered as NASA 832. The cambered leading edge of the wing delayed airflow separation at high angle of attack and also offloaded the outer wing panels at high mach, shifting the center of lift forward to counteract the natural tendency of the delta wing to shift the center of lift aft at higher mach numbers.

Air Force Plant 42, Palmdale, May 5, 1991

A-12 60-0924 at the future site of Blackbird Airpark in Palmdale on May 1, 1991. It still carries remnants of protective spray-on latex coating.

After the loss of the first SR-71B trainer, the rear fuselage of YF-12A, 60-6934 was mated to an engineering mockup of the SR-71A to create another trainer. The result was dubbed the "Bastard". It is in the collection of the Hill Air Force Base Museum.

The SR-71C was given a raised rear cockpit similar to the SR-71B.
