Hill Aerospace Museum offers more than 50 aircraft in both indoor and outdoor displays. These displays range from the first U.S. military trainer (a bi-wing Stearman) to the ultra-modern SR-71 Blackbird. Favorite exhibits also include a flight simulator, missiles and a smattering of aviation-oriented artwork. Visitors should keep their eyes to the sky while outside the facility; four squadrons of F-16 Vipers call Hill Air Force base home, and the fighters can frequently be seen roaring off toward their training grounds. The staff will answer questions.
