It was designed in the Spanish Colonial Revival style.","why_significant":"The nomination argues the hangar is significant for its association with Southern California's aviation industry. It was the first hangar built at Los Angeles Municipal Airport (Mines Field) and is the only structure remaining from the original airport. It hosted events such as the Graf Zeppelin's refueling stop and the National Air Races, and was used by many famous aviators.","narrative":"Hangar One is a Spanish Colonial Revival hangar on the cargo tarmac of Los Angeles International Airport. Built in 1929 by the Curtiss-Wright Company on land leased from the City, it was the first hangar at Mines Field, the site chosen for the municipal airport. Architects Gable and Wyant gave it a red tile roof, arched openings, and corner towers, a departure from the corrugated iron typical of hangars then. It could house about 18 aircraft and served as a training headquarters and flying school. Shortly after completion, the German dirigible Graf Zeppelin anchored at its tarmac during a refueling stop, and the airport hosted National Air Races in 1928, 1933, and 1936. Pilots such as Charles Lindbergh and James Doolittle used the hangar, and later tenants included the Army Air Forces. It is the only building remaining from the airport's original development and has been rehabilitated while retaining its original openings and orientation.","period_of_significance":"1929-1942","architect_builder":"Gable & Wyant","architectural_style":"Mission/Spanish Colonial Revival","criteria":["A"],"status_note":"Described as substantially intact and rehabilitated following the Secretary of the Interior's Standards; still used for air-related transportation.
