Two books that I've really enjoyed, apart from Pirate, Private and the usual A5 glossies, are:
The Shepherd - Frederick Forsyth - only a short story about a vampire pilot on Christmas Eve but extremely well written and illustrated.
Piece of Cake - Derek Robinson - ficticious tale of WW2 Hurricane pilots in N France and back in Blighty. Caused a fair amount of controversy amongst the old 'n' bold but some of the tales must have been based on fact.
