Description
NASA 844, an SR-71A flown by NASA’s Ames-Dryden Flight Research Facility (later, Dryden Flight Research Center), Edwards, California, cruises over the Tehachapi Mountains during a September 1992 flight. The aircraft is one of two SR-71As initially loaned to NASA by the Air Force for use as high-speed, high-altitude testbeds for research in such areas as aerodynamics, propulsion, structures, thermal protection materials, and instrumentation. Data from the SR-71 research program could aid designers of future supersonic-hypersonic aircraft and propulsion systems. Author unknown.

The Lockheed SR-71 "Blackbird" is a long-range , Mach 3+ strategic reconnaissance aircraft that was operated by the United States Air Force . It was developed as a black project from the Lockheed A-12 reconnaissance aircraft in the 1960s by Lockheed and its Skunk Works division. American aerospace engineer Clarence "Kelly" Johnson was responsible for many of the design's innovative concepts. During aerial reconnaissance missions, the SR-71 operated at high speeds and altitudes to allow it to outrace threats. If a surface-to-air missile launch was detected , the standard evasive action was simply to accelerate and outfly the missile. The SR-71 was designed with a reduced radar cross-section .
The SR-71 served with the U.S. Air Force from 1964 to 1998. A total of 32 aircraft were built; 12 were lost in accidents and none lost to enemy action. The SR-71 has been given several nicknames, includingBlackbird and Habu . It has held the world record for the fastest air-breathing manned aircraft since 1976; this record was previously held by the related Lockheed YF-12 .
