Narrative:Hawker Hunter Hunter F.Mk.5 WP143: Delivered 23/6/55. No operational front line service with the RAF. Delivered to the RAE at Farnborough for test flying, with particular reference into investigations related to "engine flame outs" caused when the aircraft was firing its 4 x 20mm Aden cannon
Written off (damaged beyond repair) 20/10/55: Crashed into trees at RAF Pembrey, having made an emergency landing after being struck by a ricochet from the 20mm Aden cannon it was testing (with "live" rounds) at nearby Pendine Sands range. The engine failed (flamed out) and the Hunter F.Mk.5 overshot in an emergency landing at RAF Pembrey.
The pilot had tried to make an emergency landing on one runway at RAF Pembrey, only to find that the runway selected was blocked by being already being in use by a DH Vampire on final approach. The pilot then tried to land on another runway at RAF Pembrey; although he managed to make it to within the airfield boundaries, he landed on the grass just inside the perimeter fence, and the aircraft was wrecked when it collided with trees.
According to the official Air Ministry report into the incident (File PA1716/5/3/397 - see link #5) dated 8/11/55:
"Armstrong Siddeley Motors Experimental Department (Sapphire engines): Interim report concerning failure of engine B.7042/A.643502 in Hunter WP143
All the evidence clearly indicates that the engine sustained severe compressor damage due to the entry of a foreign body when the aircraft was carrying out a low level gun firing exercise. The deposits of molten aluminium alloy on the turbine are consistent with the engine running at the time the compressor damage occurred. The rapid fall in rpm which occurred whilst the pilot was making a forced landing also indicates that the compressor was damaged prior to being involved in the forced landing".
Aircraft not repaired. Struck off charge as Cat.5(G/I) as Ground Instructional Airframe 7292M. However, the airframe proved to be too damaged for such use, and therefore the wreckage was transported to the Pendine Sands Ranges for use as a target.
Note: The aircraft involved was Hawker Hunter F.Mk.5 WP143, and not, as often quoted, "WP153". No such serial number was ever allocated (it was part of a "black out block" of serials between WP151 and WP178). Also the crash took place on 20/10/55, and not as some sources claim "1956". Nor did it ever serve with 1 Squadron RAF or as "M" of 257 Squadron.
