The Women Airforce Service Pilots (WASP), called "Women's Army Service Pilots" in some sources, was a paramilitary aviation organization. The WASP's predecessors, the Women's Flying Training Detachment (WFTD) and the Women's Auxiliary Ferrying Squadron (WAFS) organized separately in September 1942. They were the pioneering organizations of civilian female pilots, employed to fly military aircraft under the direction of the United States Army Air Forces during World War II. The WFTD and WAFS were merged on August 5, 1943, to create the paramilitary WASP organization. The female pilots of the WASP ended up numbering 1,074, each freeing a male pilot for combat service and duties. They flew over 60 million miles in every type of military aircraft. The WASP was granted veteran status in 1977, and given the Congressional Gold Medal in 2009.
Over 25,000 women applied; however, only 1,074 were accepted into the WASPs. The accepted women all had prior experience and pilot's licences. Of those accepted, the majority were white; aside from white women, the WASP had two Mexican American women, two Chinese American women (Hazel Ying Lee and Maggie Gee), and one Native American woman (Ola Mildred Rexroat). Due to the existing climate of racial discrimination, the only African American applicant was asked to withdraw her application.
By the summer of 1941, Florida native Jacqueline "Jackie" Cochran and test-pilot Nancy Harkness Love had independently submitted proposals to the U.S. Army Air Forces (the forerunner to the United States Air Force) to use women pilots in non-combat missions after the outbreak of World War II in Europe. Their motivation was to free male pilots for combat roles by employing qualified female pilots to ferry aircraft from factories to military bases, and to tow drones and aerial targets. Prior to Pearl Harbor, General Henry H. "Hap" Arnold, commander of the USAAF, had turned down both Love's 1940 proposal and that of the better connected and more famous Cochran, despite the lobbying by Eleanor Roosevelt. But he essentially promised the command to Cochran, should such a force be needed in the future. While the U.S. was not yet fighting in World War II, Cochran had gone to England to volunteer to fly for the Air Transport Auxiliary (ATA). The ATA had been using female pilots since January 1940, and was starting to also train new pilots. The American women who flew in the ATA were the first American women to fly military aircraft. They flew the Royal Air Force's frontline aircraft—Spitfires, Typhoons, Hudsons, Mitchells, Blenheims, Oxfords, Walruses, and Sea Otters—in non-combat roles, but in combat-like conditions. Most of these women served in the ATA during the war. Only three members returned to the U.S. to participate in the WASP program. The U.S. was building its air power and military presence in anticipation of direct involvement in the conflict, and had belatedly begun to drastically expand its men in uniform. This period led to the dramatic increase in activity for the U.S. Army Air Forces, because of obvious gaps in "manpower" that could be filled by women. After the attack on Pearl Harbor, to compensate for the manpower demands of the military, the government encouraged women to enter the workforce to fill both industrial and service jobs supporting the war effort.
