This early-1940s photograph shows a twin-engine US Army Air Forces trainer, marked '92A,' distinguished by its unusual tricycle landing gear -- a feature most closely associated with the Curtiss AT-9 'Jeep.' Introduced to prepare pilots for larger twin-engine combat aircraft like the B-25 Mitchell and A-20 Havoc, these fast, demanding trainers played a critical if lesser-known role in building the pilot corps of World War II. The plain star insignia, used before mid-1943, places this photograph in the war's early years. Project: 218470
