Narrative:de Havilland DH.115 Vampire T.Mk 11 XE866: Delivered 27/10/1954. Sole operational service career was with 4 FTS, RAF Worksop, Nottinghamshire.
Written off (destroyed) 8/8/1957: At 07:50 on the 8th August 1957 Flying Officers Jones and Brett took off in Vampire XE866 for a training flight from RAF Worksop. F/O Brett, under the instruction of Jones, was to carry out a mixture of high speed flying, medium level aerobatics and controlled descent through cloud.
F/O Brett had been undertaking a training session at 40,000 feet, culminating in a high speed descent at 85% the speed of sound. They were in the process of heading back to base at RAF Worksop after a controlled descent through cloud, when the crash occurred.
The Board of Inquiry determined that the cause of the crash was a misreading of the altimeter. It should be noted that the device used in Vampire T.11s was the Mk.14 altimeter, which was later discontinued, because the needle showing tens of thousands of feet was tiny, and easily obscured by the other hands, rather like the hands of a watch or clock temporarily obscuring each other.
It is possible that, during the high speed descent, Flying Officer Brett may well have misread the tens of thousands of feet indicated on the altimeter, and the Inquiry believed the same, that both crew men thought they were some 10,000 feet higher than they actually were as they descended.
Note that some sources give the crash location as "Crashed into Moscar Moor just below Crow Chin on Stanage Edge"., and others as "High Neb, Stanage Edge". The official Board of Inquiry into the incident (held at the National Archives at Kew under file reference AVIA/5/37/2888 - see link #4) gives the crash location as "Worksop" - which is where the aircraft took off from, not where it come down!
