The origins of the DC-3 trace back to American Airlines request to Douglas to build a larger, updated version of then flying passenger aircraft. It was the introduction of the DC-3 that initially made American Airlines more successful than its competitors.
The DC-3 was the first twin engine aircraft able to earn a profit without the need to haul freight. It was an instant success. It was first flown by American Airlines in June of 1936. Other airlines based in the United States soon followed American’s use of the DC-3 including Delta, Eastern, TWA and United.
Worldwide sales of the DC-3 followed including a purchase by KLM Royal Dutch Airlines. DC-3 aircraft were soon flying the world’s longest schedule route. It was from Amsterdam, the Netherlands to Sydney, Australia.
DC-3 aircraft service was flown by Cubana de Aviacion airlines from Havana, Cuba to Miami Florida.
It is estimated that in the years just prior to the start of World War II, the DC-3 made all but five percent of the total commercial airline flights throughout the world. When World War II broke out, many DC-3 aircraft were used for troop transports and air ambulances.
Some 600 DC-3 aircraft were in commercial airline service and an additional 15,000 were in military service.
