Awwww.... at least break the options up by which war the movie comes from.
WWI: The Blue Max -- no question here: the planes, the fighting, and Ursula Andress scantily clad.  A big thumbs up.
Zeppelin -- giant flying gasbag takes german super-secret mission (and british double agent) to Scotland and (most of the way) back.  Much cooler giant flying gasbag here than you will ever see on ch 200.  
WWII: 12 O'Clock High.  -- the movie that makes me take up B-17s to Bishland.  Note to HT: if you like this movie, how about giving us B-17 drivers some decent strats to bomb?
Flying Tigers: -- hey, Its JOHN WAYNE and P40s.  Particularly like the suicide airliner/bomber ending with all the cans of nitroglycerine.
Air Force: another good B-17 movie.  Particularly like the part where they add a "field mod" tailgun to a early model B-17.  
Korea:  Bridges of Toko-Ri - OK if you like William Holden.  
Viet Nam:  Flight of the Intruder -- where else can you see A-6s and have a black-italian mafia-connected squadron leader?
