With the outbreak of the conflict, the US Army Air Corps (USAAC) established the 99th Flying Training Squadron, with the graduates going on to form the Tuskegee Airmen. By the end of the Second World War, around 1,000 Black aviators had trained at Tuskegee, along with 14,000 bombardiers, navigators, aircraft mechanics and maintenance crews, control tower operators and support staff. Following the end of World War II, the Tuskegee Airmen returned home to a country still grappling with racial inequality.
