I highly recommend visiting the museum in Dayton if you're even a slight aviation nerd and happen to be in the region. Its worth the drive. Where else can you see a U2, a B2, an F22, an SR-71, and an F117 all the same hangar? Trick question, they have the only B2 on display!<p>They have a massive range of the history of aviation with a good mixture of foreign birds as well as US aircraft. I'm personally a fan of those classic Douglas planes, they're so incredibly iconic and have quite a showing at the museum.<p>EDIT: I guess I should clarify the relation to this article. The actual prototype is housed at the Air Force Museum in Dayton, OH along with the C-97 that carried it on display. They have a small exhibit with some example photos of its technology. Its literally right next to the B2 on display.
