During WWII, the USAAF accepted 3,144 C-46s (1,410 were C-46Ds) for hauling cargo and personnel and for towing gliders. This C-46D was retired from USAF service in Panama in 1968 and is now on display at the national Museum of the USAF as an aircraft flying the 'Hump', transporting war materials over the Himalayas from India to China after the Japanese had closed the Burma Road.
