Den Douglas C-47 Skytrainor Dakota (RAF designation) is a military transport aircraft developed from the civilian Douglas DC-3 airliner. It was used extensively by the Allies during World War II and remains in front line service with various military operators.
The specialized C-53 Skytrooper troop transport started production in October 1941 at Douglas Aircraft’s Santa Monica, California plant. It lacked the cargo door, hoist attachment and reinforced floor of the C-47. Only a total of 380 aircraft were produced in all because the C-47 was found to be more versatile.
