The series of three-engine Ford Trimotor aircraft produced during the 1920s and 1930s were classic planes of the era. Most major airlines used these planes, especially the 4-AT, during this time, and smaller and more remote airlines around the world continued to use the plane for many more years. Some are still in use. The Trimotor's most famous single flight was Admiral Richard Byrd's flight over the South Pole on November 28, 1929, when the Floyd Bennett carried Byrd and three companions around the Pole. The first Ford Trimotor, the 2-AT Pullman, was developed by Stout Metal Airplane Company in early 1925. In August, Ford Motor Company acquired Stout and produced the 3-AT, which was not a successful plane. Ford dismissed Stout and redesigned the plane. The new plane, the 4-AT, debuted on June 11, 1926. At the time, it was the largest civil aircraft produced in the United States. Powered by three 200-horsepower (149-kilowatt) Wright Whirlwind J4 radial engines, the 4-AT-A version of up the plane could seat up to eight passengers in its enclosed cabin, although the two pilots were exposed to the elements in their open cockpit. Called the "Tin Goose" because of its corrugated metal fuselage, it was an immediate success. Not recomended for children under the age of 3. Small parts may present choking hazard.
