The home field for the 477th was Selfridge Field, located outside Detroit, however, other bases would be used for various types of training courses. Twin-engine pilot training began at Tuskegee while transition to multi-engine pilot training was at Mather Field, California. Some ground crews trained at Mather before rotating to Inglewood. Gunners learned to shoot at Eglin Field, Florida. Bombers-navigators learned their trades at Hondo Army Air Field and Midland Air Field, Texas or at Roswell, New Mexico. Training of the new African-American crewmen also took place at Sioux Falls, South Dakota, Lincoln, Nebraska, and Scott Field, Belleville, Illinois. Once trained, the air and ground crews would be spliced into a working unit at Selfridge.
