Douglas C-47D (Skytrain) Few aircraft are as well known or were so widely used for so long as the C-47 or "Gooney Bird" as it was affectionately nicknamed. The aircraft was adapted from the DC-3 commercial airliner which appeared in 1936. The first C-47s were ordered in 1940 and by the end of WW II, 9,348 had been procured for AAF use. They carried personnel and cargo, and in a combat role, towed troop-carrying gliders and dropped paratroops into enemy territory.
After WW II, many C-47s remained in USAF service, participating in the Berlin Airlift and other peacetime activities. During the Korean Conflict, C-47s hauled supplies, dropped paratroops, evacuated wounded and dropped flares for night bombing attacks. In Vietnam, the C-47 served again as a transport, but it was also used in a variety of other ways which included flying ground attack (gunship), reconnaissance, and psychological warfare missions.
