Now this is a piece of cake, here's my top lot...
Winged Victory
"No Parachute"
and I'm going to throw in Alex Revell's effing brilliant history of 56 Sqn
High in the Empty Blue, I know, I know, it's not a novel or memoir but it's a damn good piece of literature.
Rainbase, you really should read Winged Victory if you like Derek Robinson, I'd put money on the fact that he used it as inspiration for his novels.
