Pima Air & Space Museum  The Pima Air & Space Museum, located in Tucson, Arizona, is one of the world's largest non-government funded aerospace museums. The museum features a display of nearly 300 aircraft spread out over 80 acres (320,000 m²) on a campus occupying 127 acres (610,000 m²). It has also been the home to the Arizona Aviation Hall of Fame since 1991. A large number of the museum's aircraft are displayed outside with the remainder located in one of the museum's four display hangars. In addition to the display hangars, the museum has a restoration hangar. Opened to the public in May 1976 with 48 aircraft then on display, the Museum's main hangar houses an SR-71A Blackbird, an A-10 Warthog, a United States Air Force "Through the Years" exhibit, and a mock-up of a control tower. The museum is adjacent to Davis-Monthan Air Force Base. The 309th Aerospace Maintenance and Regeneration Group (AMARG), affiliated with the base, also known as the "Graveyard of Planes" or "The Boneyard", is the largest aircraft storage and preservation facility in the world. The museum opened to the public on May 8, 1976. In early 1982 the first hangar on the site was completed. A second was built in 1987, a third in 1992, and a fourth in 1994. In 2012, the museum collaborated with artists, in "The Boneyard Project", to place some abandoned aircraft on display as canvases for art. During 2015, Boeing donated to the museum the second 787 aircraft to be built. It is exhibited in the colors of the 787 customer, ANA. In November 2016, Orbis International donated their first McDonnell-Douglas DC-10 Flying Eye Hospital to the museum, after receiving a second DC-10 from FedEx. The DC-10, which was the oldest flying example of its type at the time of its donation, is being restored for display at Davis–Monthan Air Force Base. Out of a collection of 300 aircraft, these are the most prominent:   Included in the museum's collection is an almost complete collection of American bombers and most of the Mikoyan-Gurevich fighters built during the Cold War.
