The Douglas DC-3 is a propeller-driven airliner, which had a lasting effect on the airline industry in the 1930s to 1940s and World War II.
It was developed as a larger, improved 14-bed sleeper version of the Douglas DC-2.
It is a low-wing metal monoplane with conventional landing gear, powered by two radial piston engines of 1,000–1,200 hp (750–890 kW).
The DC-3 has a cruising speed of 207 mph (333 km/h), a capacity of 21 to 32 passengers or 6,000 lbs (2,700 kg) of cargo, and a range of 1,500 mi (2,400 km), and can operate from short runways.
