Quick Summary

The DC-4 was a four-engine aircraft developed by the Douglas Aircraft Company. It was unpressurized but offered comparable performance to the Stratoliner and could carry more passengers. A key feature of the DC-4 was its tricycle landing gear, which improved passenger boarding, pilot visibility, and takeoff characteristics. The DC-4 entered production during World War II as the C-54, serving as the U.S. Army Air Forces' primary long-range transport aircraft. It was later joined by the Lockheed L-049 Constellation, which incorporated a pressurized fuselage and other advanced features, giving the United States an advantage in postwar airliner competition.1
