Moffett Field's "Hangar One" (built during the Depression era for the USS Macon) and the row of World War II blimp hangars are still some of the largest unsupported structures in the country. The airship hangar is constructed on a network of steel girders sheathed with galvanized steel. It rests firmly upon a reinforced pad anchored to concrete pilings. The floor covers ) and can accommodate six (360 feet x 160 feet) football fields. The airship hangar itself, measures long and wide. The building has aerodynamic architecture. Its walls curve upward and inward, to form an elongated dome high. The clam-shell doors were designed to reduce turbulence when the Macon moved in and out on windy days. The "orange peel" doors, weighing 500 tons (511.88 tonnes) each, are moved by their own 150 horsepower motors operated via an electrical control panel.
