1954
- January 10 – BOAC Flight 781, a de Havilland Comet flying from Rome to London on the last leg of a flight from Singapore, disintegrates in mid-air, when metal fatigue from repeated pressurization cycles compromises the fuselage, killing the 29 passengers and six crew.
- April 8 – South African Airways Flight 201, a de Havilland Comet flying from Rome to Cairo bound for Johannesburg, disintegrates in mid-air, killing all 14 passengers and seven crew; as in BOAC Flight 781, the cause is metal fatigue at stress risers at the corners of the square windows in the aluminum skin; subsequently, all pressurized aircraft windows are constructed with wide radius corners.
- July 23 – The 1954 Cathay Pacific Douglas DC-4 shootdown: a Cathay Pacific Douglas DC-4 is attacked by two PLAAF La-7 fighters and crashes off Hainan Island, killing 10 of 19 on board.
- September 5 – KLM Flight 633, a Lockheed L-1049 Super Constellation, ditches after takeoff from Shannon Airport in Ireland, killing 28 of 56 on board.
