The Ju-52 first flew in 1930 as a single engine civil aircraft. Before long it was given two more engines and designated Ju-52/3m (German - drei Motoren - “three engines”). The 3-engine aircraft was originally designed as a 17 passenger airliner. The principal user was Lufthansa that flew in Europe, Asia and South America. In the mid 1930’s a military version was produced and the Ju-52 became one of the most reliable transport aircraft. The Ju-52 saw service with military and civilian air fleets well into the 1980s.
