Lockheed C-60 Loadstar
The C-60 is a twin-engine transport based on the Lockheed Model 18 Lodestar. During WW II the Army Air Forces used the aircraft for training and for transporting personnel and freight. First flown in 1940, the Model 18 was originally designed as a successor to the Lockheed Model 14 and the earlier Model 10 Electra.

Service with US Army and USAAF
The Army began ordering military versions of the Model 18 in May 1941. Depending upon the engines and interior configuration, these transports were given C-56, C-57, C-59 or C-60 basic type designations. Lockheed built more C-60As for the AAF (325) than any other version of the military Lodestar.
