 |  | The
            Ford trimotor was based on the Stout 2-AT Pullman.  The
            prototype 4-AT Trimotor first flew in 1926. The 4-AT and improved 5-AT were the most
            produced Ford Trimotors with around 200 being built when production
            ended in 1932.  The designation "AT" stood for
            "Air Transport". Also known as the "Tin Goose",
            the Ford Trimotor was also purchased by the U.S. Army and Navy. |
