The C-47 Skytrain was a military transport aircraft developed from the Douglas DC-3 commercial airliner. C-47s were used extensively by many countries during World War II to transport troops, cargo, tow troop-carrying gliders, drop paratroops into enemy territory and air evacuate the sick or wounded. They were one of the most successful and beloved airplanes of all time, with over 10,000 being produced in the United States during the war. Among the C-47’s contributions were transporting troops to Normandy on D-day and flying supply missions over the Himalayas from India to China.
