2/15/1946: Maiden Flight of the DC-6

DALLAS – Today in Aviation, The Douglas DC-6 took to the skies for the first time in 1946. The aircraft was a development of the DC-4 with increased performance, greater payload and a pressurised cabin.

Initially intended for military service, the DC-6 was commissioned for the US Air Force as project XC-112 in 1944. This would be the version that would operate the inaugural flight.

However, by the time Douglas had designed the airliner, the Second World War was coming to an end, and the military no longer required the type.

Passenger Model

Douglas decided to convert the type into a passenger variant, and the DC-6 was born. The civilian variant first flew on June 29, 1946, with deliveries to American Airlines (AA) and United Airlines (UA) in November of that year.

In 1952, Pan Am (PA) introduced the upgraded DC-6B onto transatlantic flights. It was also one of the first aircraft in the world to fly regular round-the-world scheduled service. The aircraft proved popular with airlines across the globe, from Ansett (AN) in Australia to Wardair (WD) in Canada.

World Beater

By the mid-1950s, the type was gradually replaced by the DC-7 and soon the emerging airliners of the jet age, such as the Boeing 707 and Douglas’s own DC-8.

However, the DC-6 would outlive the DC-7, especially with cargo operators, owing to its more economical engines. Indeed the DC-6 was renowned as one of the world’s greatest piston-engined airliners. Between 1947 and 1959, Douglas built a total of 704 DC-6s, 167 of them military versions.
