Following proving flights by United Airlines of the DC-4E it became obvious that the 52-seat airliner was too large to operate economically and the partner airlines[a] recommended a long list of changes required to the design. Douglas took the new requirement and produced a new design, the DC-4A, with a simpler unpressurised fuselage, R-2000 Twin Wasp engines and a single fin and rudder. Both designs included tricycle landing gear, unlike the
predecessor 2-engine DC-3.

The Douglas DC-4 is a four-engine (piston) propeller-driven airliner developed by the Douglas Aircraft Company. Military versions of the plane, the C-54 and R5D, served during World War II, in the Berlin Airlift and into the 1960s. From 1945, many civil airlines operated the DC-4 worldwide.
