About Hangar 9, Brooks Air Force Base
Brooks City-Base in San Antonio, Texas, the former Brooks Air Force Base, is home to Hangar 9, a historic aircraft hangar from 1918. It ranks as the oldest aircraft storage and repair facility of the U.S. Air Force. Besides the ASUW Shellhouse, no other hangar from World War I survives. It received National Historic Landmark designation in 1976, and it has been restored as an events venue.
The hangar sits on the northern corner formed by Inner Circle Road and Challenger Drive. The building is a wood frame of two stories under a wide gambrel roof, which massive wooden trusses hold up. Vertical board siding covers the exterior, and windows dot the long sides. Each of its north and south facades has four 4.9 m (16 ft) rail-mounted sliding doors, through which aircraft originally moved in and out. Inside, it is essentially unfinished, with the wall studs and roof trusses left exposed.
It was one of sixteen similar wooden buildings put up at Brooks Field in early 1918, and by the 1960s it was the only one left. When the Air Force proposed tearing it down, the Bexar County Historical Society received permission to restore it. In 1968 it was dedicated under the name Edward H. White II Aviation Museum, and the museum closed in 2011 along with the base. The hangar was later restored as an events venue for weddings and corporate events, a step in redeveloping the base.
