The Lockheed SR-71 “Blackbird” is a long-range, high-altitude, Mach 3+ strategic reconnaissance aircraft developed and manufactured by the American aerospace company Lockheed Corporation.
It was operated by both the United States Air Force (USAF) and NASA.
SR-71A was the main production variant.
SR-71B was a trainer variant.
SR-71C was a hybrid trainer aircraft composed of the rear fuselage of the first YF-12A (S/N 60-6934) and the forward fuselage from an SR-71 static test unit.
The YF-12 had been wrecked in a 1966 landing accident.
This Blackbird was seemingly not quite straight and had a yaw at supersonic speeds.
