Curtiss-Wright C-46 Commando
The largest and heaviest twin-engine aircraft to see service with the Army Air Forces, this transport gained its greatest fame in airlifting supplies over "the Hump" (the Himalayan Mountains) in the China-Burma-India theater in World War II, although it saw action in every theater.

The C-46 was the largest and heaviest twin-engine transport aircraft to see service with USAAF.  Some C-46s were used for glider towing and a few served in the Korean Conflict with the Combat Cargo Command.

  A total of 1,490 C-46As were built, which included 160 R5Cs for the Marine Corps. The other major variant was the C-46D, with 1,410 aircraft built.

C-46s were in limited Air Force service as late as 1969. Many went into civilian hands after World War II, and a fair number are still in use today.
