SR-71 Blackbird aircraft. SR-71 Blackbird (YF-12C) aircraft taking off from NASA Dryden Flight Research Center, Edwards Air Force Base, California, USA. This aircraft was designed and built at the Lockheed Company's legendary 'Skunk Works' and was operational between 1964 and 1998. About 85% of the aircraft structure is made from titanium and titanium alloys; ironically the metal was obtained covertly from the USSR at the height of the Cold War. The SR-71 holds two world records for air-breathing manned aircraft: the fastest sustained speed (3529.6 kilometres per hour, Mach 3.32) and the greatest sustained altitude at 25, 929 metres (85, 069 feet). A total of 32 SR-71 aircraft were built. | |
