if you ever get the opportunity, go to the Air Force Museum in Dayton Ohio.... I promise you won't be disappointed!
My wife took me there on our honeymoon.
It is the grandest flight museum, in my opinion.
My favorite flight museums are: USAF (largest collection), Udvar Hazy (a close 2nd in collection), Museum of Flight (see below), Flying Heritage Collection (for its flyable planes), and Planes of Fame (lots of flyable ones there, too).
Of them all, the one I've been to most is the Museum of Flight because of pilot panel discussions. They've had numerous aces and bomber pilots give talks there -- Bud Anderson, George Chandler, Steve Pisanos, Lou Luma, Arthur Jeffrey, Dean Caswell, Kelly Gross, George Novotny, Harry Farrier (one of the few TBM survivors at Midway), Warren Omark (who got a torpedo hit on the Hiyo, sunk in the Battle of the Philippine Sea), and a lot more; pilots of P-51's, P-47's, P-38's, P-40's, P-39's, F4U's, F6F's, B-17's, B-24's, B-25's, Spitfires, Mosquitos, SBD's, TBM's, Beaufighters, P-61's; pilots who fought over Germany, France, Italy, the Mediterranean, North Africa, the Pacific Ocean, Pacific Islands, and Japan; pilots who did bomber escort, fighter sweeps, high-alt bombing, fighter bombers, night fighters, dive bombers, torpedo bombers, photo recon. It's an amazing place for that.
