I've been to quite a few aviation museums and I'd have to say that the best of them all was the one in Dayton,Ohio. I'm sure some of you have been there before. They have quite an aray of aircraft on display, including the Spirit of St.Louis hanging from the ceiling. The fun doesn't just stop inside the massive hanging. The have numerous aircraft on display outside of the museum.
The SAC Headquarters in Louisiana was very interesting. The museum was right on the military base. Every now and then a B-52 or F-16 would fly by. My favorite plane there was the B-17.
The most unique musem I have been to was on the aircraft carrier Lexington in Corpus Christi, Texas. It's quite the experience when you think how everyting on an aircraft carrier works. Just standing in the middle of the flight deck was a feeling of awe.
What are your favorite museums?
