In 1966, an SR-71 Blackbird Disintegrated at Mach 3.18. The Pilot Survived Without Ever Pulling His Ejection Handle

The article analyzes the SR-71 Blackbird's paradoxical safety record: while no enemy missile or fighter ever downed the aircraft over decades of reconnaissance missions, 12 of the 32 Blackbirds built (37%) were destroyed in accidents. The only fatality occurred on January 25, 1966, when a test flight at Mach 3.18 and 78,000 feet suffered an inlet unstart, causing the aircraft to disintegrate. Pilot Bill Weaver survived without pulling his ejection handle—he was torn from the cockpit unconscious, his pressure suit inflated automatically, and his parachute deployed at 15,000 feet. Reconnaissance systems specialist Jim Zwayer died from a broken neck during the breakup. The article attributes most losses to the extreme physics of Mach 3 flight, including unstarts, drag chute failures, and in-flight explosions, with the majority occurring in the program's first six years.
