In 1931, the United States Air Corps issued an order to update and modify the Type A-1 flight jacket. The significant design changes of the jacket included replacing the button down front with a zipper and the knit collar with a leather drop fall collar. The new jacket was designated -- Type A-2. This jacket became associated with American pilots serving on every front during World War II and is still issued by the U.S. Air Force today. Many pilots and aircrews modified their jackets with custom artwork that depicted the name of their aircraft. These jackets are nick named "Painted Ladies" for the common practice of using the pinup girls for the aircraft's name and nose art.
This particular Type A-2 was worn by Gen. Claire Chennault. Chennault formed the famous fighter group of American volunteers in China known as the Flying Tigers. Once the United States entered the war, he went on to command the 14th Air Force in China.
