Junkers JU-52 / LufthansaThe Ju 52 tri motor was first built in the 1930s, yet remained in service for more than a quarter century. This transport made its maiden flight in April 1931 and flew with Lufthansa Airlines. Three years later a heavy bomber version appeared, but was obsolete by 1939, but because of its durability, simplicity of design, and handling characteristics it continued to serve throughout WW II as a versatile workhorse of the German transport fleet.
