I've just had a quick look at some of the Meteor accident statistics mentioned at the end of Nick Carter's book - 'Meteor Eject', and it lists about 24 fatals during 1945/46. Not much detail to go on, but some possibilities:-
18/05/45 EE238 Mk3 RAE
"Crashed doing low level aerobatics"
02/01/46 EE335 Mk3 74Sqn
"Hit ground during low level beat up"
08/03/46 EE344 Mk3 74Sqn
"Crashed during unauthorised beat up"
During RAF service, a total of some 890 Meteors crashed, killing nearly 450 aircrew!
