In June 1941, the 99th Pursuit Squadron was transferred to Tuskegee, Alabama and remained the only Black flying unit in the country, but did not yet have pilots. The famous airmen were actually trained at five airfields surrounding Tuskegee University (formerly Tuskegee Institute)--Griel, Kennedy, Moton, Shorter and Tuskegee Army Air Fields. The flying unit consisted of 47 officers and 429 enlisted men and was backed by an entire service arm. On 19 July 1941, thirteen individuals made up the first class of aviation cadets (42-C) when they entered Preflight Training at Tuskegee Institute. After primary training at Moton Field, they were moved to the nearby Tuskegee Army Air Field, about to the west for conversion training onto operational types. Consequently, Tuskegee Army Air Field became the only Army installation performing three phases of pilot training (basic, advanced, and transition) at a single location. Initial planning called for 500 personnel in residence at a time.
