The Cessna AT-17, later designated UC-78 in its utility role, was a twin-engine advanced trainer aircraft used extensively by the U.S. Army Air Forces during World War II. Nicknamed the “Bamboo Bomber” due to its wood-and-fabric construction, the aircraft was originally developed from the civilian Cessna T-50 and quickly adapted for military use.
Designed for training bomber pilots and multi-engine crews, the AT-17 featured retractable landing gear, side-by-side seating for instructors and students, and twin Jacobs R-755 radial engines. It was also used for light transport, liaison duties, and even executive transport under the UC-78 designation.
Over 4,600 units were produced, and its docile handling and versatility made it one of the most important training aircraft of the war. Today, surviving examples can still be found at airshows, flying museums, and in the hands of dedicated warbird enthusiasts.
