In 1957, the CIA and Air Force began searching for a reconnaissance aircraft that would be invulnerable to Soviet surface-to-air missiles. Lockheed won the design competition and began serious development work in 1959, which finally resulted in the SR-71. Colonel Bledsoe, who flew the SR-71 for seven years, will explain the building and operation of the aircraft, with special emphasis on its unique astro-inertial navigation system.
