Douglas DC-6 / C-118 Liftmaster Piston Transport Family

The Douglas DC-6 was a pressurized four-engine piston transport that extended the DC-4 lineage with greater speed, payload, range, and passenger comfort. First flown in 1946, it became a major postwar airliner, flew scheduled around-the-world services, and generated C-118/R6D military and MC-118 aeromedical transports; freighter conversions and a small number of preserved aircraft kept the design visible after the jet transition.
