On 29 June 1946, one of the Dakota aircraft belonging to the Royal Air Force Police with 20 NCOs on board crashed at the airport in a storm with no survivors. On 13 March 1954, a BOAC Lockheed Constellation, G-ALAM Belfast carrying mail crashed while attempting to land at Kallang Airport en route to London from Sydney.
