Hangar One, with its exceptional character, innovative design and technical virtuosity, has long been one of the most recognizable landmarks of California's Silicon Valley.  This cavernous, dome-shaped structure, built in 1932 to house U.S. Navy dirigibles, measures 200 feet tall and covers more than 8 acres of land. During World War II, it served as a docking station for the USS Macon, the largest aircraft in the world at the time. The hangar dominates the landscape at Moffett Field, towering over an impressive array of 1930s-era Spanish Colonial Revival military buildings, which are now part of NASA's Ames Research Center.  Hangar One is notable for its colossal Streamline Modern form, and is regarded as emblematic of Silicon Valley's contributions to aviation and space advancement as well as technology research and development.
