full_context: Document 1: Rosie the Riveter: Rosie the Riveter is a cultural icon of World War II, representing the women who worked in factories and shipyards during World War II, many of whom produced munitions and war supplies. These women sometimes took entirely new jobs replacing the male workers who joined the military. Rosie the Riveter is used as a symbol of feminism and women's economic power. Similar images of women war workers appeared in other countries such as Britain and Australia. Images of women workers were widespread in the media as government posters, and commercial advertising was heavily used by the government to encourage women to volunteer for wartime service in factories. "Rosie the Riveter" became the subject and title of a song and a Hollywood movie during WWII.
Document 2: A-2 jacket: The Type A-2 leather flight jacket is an American military flight jacket originally invented and developed for and closely associated with World War II U.S. Army Air Forces pilots, navigators and bombardiers, who often decorated their jackets with squadron patches and elaborate artwork painted on the back. Sometimes casually referred to as a bomber jacket, its original designation was "Jacket, Pilot's (summer)", and its wartime usage was limited neither to pilots nor to bomber crews.
Document 3: Women Airforce Service Pilots: The Women Airforce Service Pilots (WASP), called "Women's Army Service Pilots" by 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.
Document 4: Willa Brown: Willa Beatrice Brown (January 22, 1906 – July 18, 1992) was an American aviator, lobbyist, teacher, and civil rights activist. She was the first African-American woman to earn her pilot's license in the United States, the first African-American woman to run for the United States Congress, the first African-American officer in the US Civil Air Patrol, and the first woman in the United States to have both a pilot's license and a mechanic's license. A lifelong advocate for gender and racial equality in flight and in the military, Brown not only lobbied the U.S. government to integrate the U.S. Army Air Corp and include African Americans in the Civilian Pilot Training Program (CPTP), but also co-founded the Cornelius Coffey School of Aeronautics with Cornelius Coffey, which was the first private flight training academy in the United States owned and operated by African Americans. She trained hundreds of pilots, several of whom would go on to become Tuskegee Airmen.

During World War II, she was part of the first group of United States women to fly military aircraft, which they did in a war zone for the civilian British Air Transport Auxiliary. She was later a member of the civilian contract labor Women Airforce Service Pilots. After the war, she taught instrument training in Brazil. When President Harry S. Truman authorized the integration of women into the military, she served with Women in the Air Force and was based in Texas, Alabama, and finally London until her death. Raines was the first woman in Georgia to earn a pilot's license, and has been inducted into both the Georgia Aviation Hall of Fame and the Georgia Women of Achievement.

Strohfus, one of just 1,074 female pilots to earn silver wings for the WASPs, flew noncombat missions from 1943 to 1944, often ferrying military planes throughout the United States. She also trained male air and infantry gunners at Las Vegas Army Airfield during the early 1940s. Elizabeth Strohfus was the recipient of two Congressional Gold Medals for her service in the WASPs and was inducted into the Minnesota Aviation Hall of Fame.

The Prop and Wings originated as branch insignia of the United States Army Air Service in 1920, and remained such from 1926 to 1947 for the successor United States Army Air Corps. Approximately 90% of all officers serving in the United States Army Air Forces were commissioned in the Air Corps and wore the insignia. Versions of the insignia are still used by the United States Air Force and the United States Army Aviation Branch.
Document 9: Women Airforce Service Pilots Badge: The Women Airforce Service Pilots Badge is an award of the United States Army that was issued during the Second World War. The badge created for the Women Airforce Service Pilots, or WASP (not WASPs, because the acronym already includes the plural "Pilots"), was awarded to more than a thousand women who had qualified for employment as civilian, non-combat pilots of military aircraft used by the U.S. Army Air Forces during World War II. The first wings were privately and hastily designed and paid for out of the pockets of Floyd Odlum and his wife, Jacqueline Cochran, who in 1942 became the head of WASP.
Document 10: Women's Flying Training Detachment: The Women's Flying Training Detachment was a group of women pilots during World War II. Their main job was to take over male pilot's jobs, such as ferrying planes from factories to United States Army Air Force installations, in order to free male pilots to fight overseas. They later merged with the Women Airforce Ferrying Squadron (formerly the Women's Auxiliary Ferrying Squadron) to form the Women Airforce Service Pilots.

The United States Coast Guard is the only branch that does not issue its own Parachutist Badge, but its members are authorized to receive the Parachutist Badges of other services in accordance with their prescribed requirements. The DoD military services are all awarded the same Basic Parachutist Badge. The Army and Air Force issue the same Senior and Master Parachutist Badges while the Navy and Marine Corps issue the Navy and Marine Corps Parachutist Badge to advanced parachutists. The majority of the services earn their Basic Parachutist Badge through the U.S. Army Airborne School.
Document 13: Elizabeth Chambers (pilot): Elizabeth "Betty" Maxine Chambers (August 25, 1920 − May 11, 1961) was one of the first female pilots in the Women Airforce Service Pilots (WASP) program in which women took on non-combat flying duties so more male pilots were available for combat.
