The museum at what many consider to be the birthplace of supersonic flight chronicles the rich history of flight testing. Numerous airplanes are on exhibit, from the first F-16B to the giant B-52D bomber. The 3½-hour walking and driving tour is open to the public once a month. To take the tour you must pass a security screening at least a week in advance (a month for non-U.S. residents). On the base's website, click Tours for details.
