Douglas DC-6
The Douglas DC-6 was a pressurised evolution of the DC-4, letting it fly higher, above much of the rough weather that shook earlier unpressurised airliners. It became one of the most popular postwar airliners, competing closely with Lockheed's Constellation on the world's premier long-haul routes. Its rugged radial engines and simple systems have kept a surprising number flying today as firefighting tankers and cargo haulers. Few airliner designs from the propeller era have had as long a working life as the DC-6.

The DC-6 pressurised the DC-4's airframe to fly above rough weather, and its rugged radial engines still keep many flying today as firefighting air tankers.
