It is also known as Hangar Nine and the Edward H. White II Museum.","why_significant":"The nomination calls it probably the oldest existing aircraft hangar at any United States military base and the only surviving example of sixteen Army Air Service hangars built at Brooks Field in World War I. It is tied to the primary flight training of many noted pilots. It was also renamed for its association with the White family, including astronaut Edward H. White II.","narrative":"Hangar Nine is a wood frame aircraft hangar at Brooks Air Force Base in San Antonio, Texas. The government built it in 1918 as a temporary structure, one of sixteen Army Air Service hangars at Brooks Field during World War I. It is now the only one of those hangars that survives, and is probably the oldest existing aircraft hangar at any United States military base. The main building has a nearly flat bolted wood truss roof in a modified gambrel form, large sliding wooden end doors made of diagonally braced panels, and braced wood side walls with stacked double sash windows. Brooks Field trained primary military aviators, including Charles Lindbergh and several later Air Force Chiefs of Staff, while instructors included Claire Chennault. The hangar was renamed the Edward H. White II Museum for the family of the first American to walk in space. Texas designated it a Recorded Texas Historic Landmark in 1967, and local citizens raised funds to restore it.","period_of_significance":"1918","architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"Listed as in good condition and altered, on its original site; a restoration to its original condition was being funded by San Antonio citizens, with the intent to serve as an early aviation museum.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:19.401497-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/79/9712/40971279/content/electronic-records/rg-079/NPS_TX/70000895.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/70000895/1cc81e0a83-800.webp","url_1600":"https://nationalhistoricalregister.com/media/70000895/1cc81e0a83-1600.webp","licence":"CC BY-SA 4.0","author":"Renelibrary","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Hangar91_(1_of_1).jpg\" rel=\"noopener\">Renelibrary</a>, <a href=\"https://creativecommons.org/licenses/by-sa/4.0\" rel=\"license noopener\">CC BY-SA 4.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Hangar91_(1_of_1).jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/40971279","wikipedia":"https://en.wikipedia.org/wiki/Hangar_9,_Brooks_Air_Force_Base","wikidata":"https://www.wikidata.org/wiki/Q5647897"},"indexable":true,"url":"https://nationalhistoricalregister.com/texas/bexar-county/hangar-9-70000895/"}
