This air museum boasts an impressive assortment of vintage military aircraft of a wide variety. Indoor museum contains an extensive collection of military uniforms and other memorabilia. But the crown jewel of the collection is a VC-9 that served as official Air Force One for 6 presidential administrations, from 1975 to 2005.
If you go:
Open daily 9 to 4 except for major holidays. Admission charged, but you can get a good view of most of the aircraft from outside the fence. Additional charge for Air Force One tours.
