Narrative:
Written off 13/03/1957: Hunter XF427 took off from RAF Odiham, Hampshire to carry out a practice diversion to RAF Manston, Kent. As briefed, the pilot was passed details of the weather at Andover (Hampshire) and Selsey Bill (West Sussex). Nothing further was heard from this aircraft, and it was destroyed when it dived into the ground from a great height, flying through very adverse weather conditions.

XF427 Dived into the ground inverted at high speed at Bouldnor, two miles east of Yarmouth, Isle of Wight after the pilot lost consciousness. (Possibly due to anoxia - oxygen starvation: it is reported that the pilot had experienced a similar "episode" two years earlier). He did not eject and was killed.

Crew of Hunter XF427:
Flight Lieutenant Michael Adrian CROOK, RAF (pilot, Service Number 607445, aged 23) - killed on active service 13/3/1957.
