This photograph shows a Ford Tri-Motor transport aircraft, registration NC414H, operated by Pan American Airways and photographed at France Field in the Panama Canal Zone. Known affectionately as the 'Tin Goose' for its corrugated aluminum skin, the Ford Tri-Motor was one of the most significant early commercial airliners, helping establish scheduled passenger air service across the Americas during the late 1920s and 1930s. Pan American Airways used aircraft like this to pioneer air routes connecting the United States to Central and South America, with France Field serving as a key regional waypoint. Project: 218476
