Ju-52 was a German tri-motor transport aircraft manufactured from 1931 to 1952. It saw both civilian and military service during the 1930s and 1940s. In a military role, it flew with the Luftwaffe as a troop and cargo transport and briefly as a medium bomber. The Ju 52 continued in postwar service with military and civilian air fleets well into the 1980s. -militaryaviationmuseum.org
