Summary and Key Points: An American SR-71 Blackbird lost one engine to an inlet unstart at 83,000 feet and Mach 3 during a reconnaissance mission over Vladivostok, the major Soviet port on the Pacific.
-The pilot immediately shut down the second engine to prevent catastrophic asymmetric thrust from tearing the aircraft apart — leaving the SR-71 in an uncontrolled descent with zero thrust over Soviet territory. The pilot and Reconnaissance Systems Officer refused to eject. They recovered the aircraft and diverted to South Korea for repairs.
