Located at Hill Air Force Base south of Ogden near Roy, this free museum has one of the best collections of American military aircraft in the country. Two enormous hangars showcase over 90 aircraft, from canvas-covered World War I biplanes to the SR-71 Blackbird, the fastest air-breathing aircraft ever built. The Cold War collection is particularly strong: a full lineup of the "century series" fighters (F-100, F-101, F-102, F-104, F-105, F-106) in various states of preservation fills one hangar.
The outdoor flight line includes a B-52 Stratofortress, a B-47 Stratojet, and a B-1B Lancer, among others. Admission is free, which makes the Hill Aerospace Museum one of the best value days out in northern Utah. The base is about 15 miles south of central Ogden; bring a photo ID for the gate, which is required for access to Hill Air Force Base property.
