Thunderbird Field was a military airfield in Glendale, Arizona, used for contract primary flight training of Allied pilots during World War II. Created in part by actor James Stewart, the field became part of the United States Army Air Forces training establishment just prior to American entry into the war and was re-designated Thunderbird Field #1 after establishment of Thunderbird Field #2 at nearby Scottsdale, on 22 June 1942. Thunderbird # 1 is located southeast of the intersection of West Greenway Road & North 59th Avenue in Glendale, Arizona.
