: It could survey 100,000 square miles of territory per hour from its cruising altitude. Engineering & Design Innovations

To survive the extreme heat generated by friction at Mach 3+, the aircraft required radical design solutions: LockheedSR71Blackbird.rar

: The aircraft used its fuel as a heat sink to cool the air-conditioning system and internal components before the fuel was burned. Legacy and Successors Aircraft Report: Lockheed SR-71 Blackbird : It could survey 100,000 square miles of

: Fuselage panels were designed to fit loosely on the ground to allow for expansion during high-speed flight. This caused the aircraft to leak JP-7 fuel while stationary. This caused the aircraft to leak JP-7 fuel while stationary

: Its Pratt & Whitney J58 engines acted as a turbojet-ramjet hybrid, becoming most efficient at speeds above Mach 3.

: On July 28, 1976, it set absolute records for speed (2,193.167 mph) and altitude (85,068.997 feet).
