Douglas DC-4E Experimental Four-Engine Airliner Family

The Douglas DC-4E was a one-off experimental airliner developed from a United Airlines requirement for a larger, more capable successor to the DC-3. Its tricycle landing gear, power-assisted controls, auxiliary power equipment, and advanced systems made it an ambitious prewar testbed; the costly design was not produced, but its experience fed into the simpler DC-4 that became a major wartime and postwar transport.
