Coff,
805 was definitely on the inventory of 6AEF 1977 - 1979. I had the great pleasure of accompanying some fine "drivers airframe" in the aircraft. Unfortunately I have few memories of exactly who. It may well have been the aircraft I put on the grass, whilst attempting to taxy it back to the pan (under supervision of course). Something about driving it on the ground was well beyond my Ken, as they say.
WB586 A Chipmunk T.10
WK589 C Chipmunk T.10
WP805 D Chipmunk T.10
WP914 E Chipmunk T.10
WZ847 F Chipmunk T.10
Whatever was, or happened to B (Bravo) ?
