The Douglas C-47 Skytrain or Dakota is a military transport aircraft that was developed from the Douglas DC-3 airliner. It was used extensively by the Allies during World War II and remained in front line operations through the 1950s with a few remaining in operation to this day.
C-47s in British and Commonwealth service took the name Dakota, from the acronym “DACoTA” for Douglas Aircraft Company Transport Aircraft. The C-47 also earned the informal nickname Gooney Bird in the European theater of operations.
The USAF Strategic Air Command had C-47 Skytrains in service from 1946 through 1967.
