Rigga,
'COMR aircraft are not used for anything but training and are often flown by non-military contract Pilots on special AOC rules.'
Not strictly true. The AAC operates 2 different types of COMR aircraft in operational roles and with mil crews.
And don't forget 84's Griffons in Cyprus
Not directly related but I found it odd that we've nearly exhausted the Z series of Serial in such a short time; bearing in mind how few aircraft the Air Force acquires these days. Apart from "real aircraft" Serials being allocated to UAVs, every foreign export machine seems to acquire a UK Serial. Presumably manufacturers don't have their own civil series of registrations anymore.
Not such a short time - the first Z series aircraft were in 1979/80 time frame, and they still allocated 'blackout blocks' in those days (until about ZH if I recall).
What is wierd is the way they have started jumping about - ZZ for the C-17, Contract HUnters and A330Ms, ZR for the A109Es, ZM for the A400M
