The 1951 Atlantic C-124 disappearance involved a Douglas C-124 Globemaster II of the 2nd Strategic Support Squadron, Strategic Air Command, which ditched into the Atlantic Ocean on the late afternoon of 23 March 1951 after reporting a fire in the cargo hold. The ditching and subsequent evacuation were successful, but the aircraft and its occupants had vanished by the time US Coast Guard Cutter Casco arrived at the last reported location.
