Air Force Museum
Curtiss AT-9 Jeep
The AT-9 advanced trainer was used to bridge the gap between single-engine trainers and twin-engine combat aircraft. The prototype first flew in 1941, and the production version entered service in 1942. The prototype had a fabric-covered steel tube fuselage and fabric-covered wings, but production AT-9s were of stressed metal skin construction.

History & service
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 Martin B-26 and Lockheed P-38. Although the AT-9 originally bore the nickname "Fledgling," it was more widely known as the "Jeep." Four hundred ninety-one AT-9s and 300 AT-9As were built before production ended in February 1943.
The aircraft on display was not complete when the museum acquired it. Some of the parts used to restore it were taken from another incomplete AT-9, while other parts had to be built from "scratch" by museum restoration specialists.

The second front was the factory and the flight line
Air power required far more than aircraft leaving a factory. Engines, radios, weapons, fuel, spare parts, tools, trained personnel, and suitable airfields had to arrive together. A machine grounded by a missing component could contribute little, however impressive its specifications. Maintenance and supply determined how much of a force was actually available on a given day.
The Second World War made this relationship visible on an extraordinary scale. Production expanded while aircraft designs continued to change. Training organizations had to turn large numbers of recruits into competent aircrew and specialists. Units then operated in climates and conditions very different from those in which the machines had been designed. Improvisation on the flight line worked alongside formal technical orders and a vast replacement system.
The smaller artifacts deserve attention within that story. A tractor moved aircraft and loads around an airfield. A jacket or oxygen mask helped a crew member function in an exposed environment. A trainer allowed procedures to be practiced without consuming a combat aircraft's life. These objects connect the spectacular mission to repeated daily work. Their history broadens the meaning of service: victory depended on people who built, supplied, repaired, taught, recorded, and cared for others, as well as those whose actions became famous in combat.
