That’s an Auster J-1 Autocrat. It was later converted to the J-1N Alpha version, but here it seems to have the original mass balanced rudder. It was built in 1946.The young lad is a corporal in the ATC (Air Training Corps).
The Auster was destroyed in an arson attack at Ingoldmells on 14 September 1991

and cancelled in 1994.

Snoopy: certainly the recovery of the aircraft is important, but the human aspect for the family of the pilot must surely prevail. One problem with the recovery of the aircraft (among many others) is that the remains of the pilot just could still be near the wreck, and its removal could spoil chances of finding, and identifying them. The bones found by qattara might not be those of F/Sgt Copping, as I have said before: human bones near the surface are not that rare in the desert.
