The Women Airforce Service Pilots (WASP) was a civilian women pilots' organization, whose members were United States federal civil service employees. Members of WASP became trained pilots who tested aircraft, ferried aircraft and trained other pilots. Their purpose was to free male pilots for combat roles during World War II. Despite various members of the armed forces being involved in the creation of the program, the WASP and its members had no military standing.

The United States Army Air Forces was the major land-based aerial warfare service component of the United States Army and de facto aerial warfare service branch of the United States during and immediately after World War II (1941–1947). It was created on 20 June 1941 as successor to the previous United States Army Air Corps and is the direct predecessor of the United States Air Force, today one of the six armed forces of the United States. The AAF was a component of the United States Army, which on 2 March 1942 was divided functionally by executive order into three autonomous forces: the Army Ground Forces, the United States Army Services of Supply, and the Army Air Forces. Each of these forces had a commanding general who reported directly to the Army Chief of Staff.
