1975: A US Air Force Lockheed C-5 Galaxy (68-0218) carrying Vietnamese orphans and American caregivers crashes while attempting an emergency landing at Tan Son Nhut Air Base, Vietnam, killing 175 of the 311 people on board. The first flight of Operation Babylift had taken off from the same airfield earlier, but suffered explosive decompression upon reaching an altitude of 23,000 feet, when locks on the rear loading ramp failed. Two of the giant plane’s four hydraulic systems failed as a result of the blowout, causing the crew to lose ability to control the rudder and elevator. On final approach the plane touched down in a rice paddy, lifted off again for about half of a mile before crashing and breaking into several pieces. It remains the most deadly crash in US Air Force history.
