During the afternoon of Friday, 12th April 1957 the pilot of this Fighter Weapons School aircraft undertook a training exercise that included single engine flying, practice single engined landings and overshoots at Leconfield airfield. Ground crew were given permission to ask for flights in the unit's two seater aircraft and on this day one of the unit's armourers requested and was granted permission to go up for a flight. During the flight the pilot made radio contact to say that he had lost control, the aircraft then dived into the ground around a mile southwest of Leconfield airfield. Both men were killed in the crash in a field on the west side of the Molescroft to Leconfield road. An investigation found likely that a fire extinguisher being carried, possibly in the hand of the passenger, had been dropped and become jammed in the control column mechanism.
