The Douglas DC-4E was an experimental airliner that was developed before World War II. The design originated in 1935 from a requirement by United Air Lines. The goal was to develop a much larger and more sophisticated replacement for the DC-3, before the first DC-3 had even flown. There was enough interest from other airlines, that American Airlines, Eastern Air Lines, Pan American Airways, and TWA joined United in providing $100,000 each toward the cost of developing the new aircraft. With a planned capacity of 42 passengers, the DC-4 (as it was then known) would seat twice as many people as the DC-3. It would be the first large airplane with a nose wheel.
