February 15 of 1946, 77 years ago today, the Douglas DC-6 took to the air for the first time.
The DC-6 is considerd by many to be the pinnacle of propliner aircraft. The last of the piston engine driven airliners before turboprop and jet airliners took over. Even after its days as an airliner were finished, the DC-6 soldiered on for many more years as a freighter and even a firefighting aircraft.
A small handful of DC-6s are still flying today, including the immacualtely maintained example owned by Red bull in the photos below:
