Here are a few to jog your memory:
Squadron Leader : How many hours in Spits?
Simon: Ten and a half, sir.
Squadron Leader : Let's make it eleven, before Jerry has you for breakfast!
Did you get one?
Sgt. Pilot Andy: All I got was a bellyful of English Channel!
Sgt. Pilot Chris: [the British Spitfire pilots are having an easy time shooting down the feared German Stuka Dive Bombers] It's like shooting rats in a barrel.
Squadron Leader Canfield: You'll be "in a barrel", if you don't watch out for the fighters!
