Awesome photograph of a formation of Curtiss AT-9 Jeeps of the 49th Twin Engine Flight Training Squadron, based at Ellington Field on the coast of Texas, in 1942. 41-12150 was damaged in a taxiing accident on 17 December 1942, and written off. This is the very aircraft that is preserved in the National Museum of the USAF, with an irregular dash in the tail number as seen here. Photo from: National Archives at College Park, Maryland

Side-by-side aircrew trainer.

The AT-9 advanced trainer was used to bridge the gap between single-engine trainers and twin-engine combat aircraft. The AT-9 was not easy to fly or land, making it particularly suitable for teaching new pilots to cope with the demanding flight characteristics of a new generation of high-performance, multi-engine aircraft such as the B-26 and P-38. This AT-9 at the National Museum of the USAF is one of only two examples that survive today.
