The 1952 Bermuda air crash occurred on 6 December 1952, when a Douglas DC-4, registered CU-T397 and operated by Cubana de Aviación, flying from Madrid to Havana, crashed into the Atlantic Ocean following a refueling stop at Kindley Air Force Base in Bermuda. There were 33 passengers and 8 crew on board the aircraft. The flight arrived at Kindley Air Force Base at 03:30.[1] After an hour's stopover spent refueling the aircraft, the DC-4 departed; at 04:45, during the initial climb, the aircraft stalled, lost height and crashed tail first into the sea. The accident killed 37 passengers and crew; three passengers and a crewmember survived the crash,[1] and were rescued shortly after the crash.
