The Lockheed SR-71 is an advanced, long range, Mach 3+ strategic reconnaissance aircraft developed from the Lockheed A-12 and YF-12 aircraft as a Black project. The SR-71 was unofficially named the Blackbird. The SR-71 was the world's fastest and highest-flying operational manned aircraft throughout its career. On 28 July 1976, an SR-71 broke the world record for its class: an "absolute altitude record" of 85,069 feet (25,929 m). Several aircraft exceeded this altitude in zoom climbs but not in sustained flight. That same day SR-71, serial number 61-7958 set an absolute speed record of 1,905.81 knots (2,193.2 mph; 3,529.6 km/h). For comparison, typical commercial flights fly at an altitude of around 35,000 to 38,000 feet.
