Beechcraft AT-11 Kansan
Based on the successful Beech Model 18 airliner and a modified bomber designed for China, the AT-11 was used by the Army Air Forces to train Bombardiers and Aerial Gunners during World War II. The standard Model 18 was modified with a Plexiglas nose for a Norden bombsight, a bomb bay capable of carrying 1,000 pounds of bombs, and flexible guns in the nose and on top. Over 1,500 Kansans were built and many remained in service with the Air Force until the mid-1950s.
