The PT-17, also known as the Stearman Model 75, is a biplane that was widely used as a primary trainer for the United States Army Air Forces during World War II. Designed in the 1930s, it features a fabric-covered wooden frame and a radial engine, making it a reliable and easy-to-fly aircraft for novice pilots. With its distinctive yellow paint and tandem seating for an instructor and student, the PT-17 became an iconic symbol of military flight training. After the war, many were sold as surplus and are still popular among aviation enthusiasts and collectors today.
