In 1993, following a Base Realignment and Closure commission decision, it was announced that Naval Air Station Alameda would be shut down.[1] In anticipation of the closure, Barbara Baack and Marilyn York, former WAVES, opened the museum in the 118,000 sq ft (11,000 m2) Hangar 41 in 1995. However, the poor condition of the hangar and a lack of money for upgrades forced it to move the collection into storage in 1997.[a] Then, in April 2001, the museum's lease for the hangar expired. As a result, it moved to the 21,000 sq ft (2,000 m2) Building 77, the former air terminal, where it reopened in 2004.[3][4]
