Narrative:
Hawker Hunter F.Mk.1 WT563: First flown at Hawker Aircraft Ltd., Dunsfold, Surrey 2-11-53. Delivered, 2-12-53. Retained as C(A) MoS trials aircraft, at Hawker Aircraft, Dunsfold.

Written off (destroyed) 20-6-1957: Crashed 200 yards east of Kidwelly Railway Station, two miles north of RAF Pembrey, Carmarthenshire. Aircraft was No 2 in a paired take off, but dropped back and started a turn to port. Pilot said he was flying in manual - aircraft straightened up but began to lose height and then began a "Dutch roll" during which it crashed. Pilot; Pilot Officer Frederick William Rupert Viel Jacques, Service Number 3520735, aged 27 years, ejected at low level but was killed.

The Board of Inquiry into the accident concluded that the accident was caused by "a false anchorage of the port aileron hydro booster release unit, which restricted port aileron movement. The fault probably happened after take off at a time when there would have been heavy demands on the airframe hydraulics"

Frederick R.V. Jacques was born 27 June 1929 at Batu Gajah, Malaya. He served with No.233 OCU based at RAF Pembrey, and was killed when his Hawker Hunter, WT563, crashed soon after take off into Kidwelly Railway Station. Frederick R.V.
