In an effort to compete with TWA (Trans World Airlines) on transatlantic routes to Europe, Pan American World Airways ordered the extended-range DC-7C (dubbed the "Seven Seas") from Douglas Aircraft. Promoted as the "Super Seven," Pan Am introduced the airliner in May 1956, on the Atlantic route from Miami to Paris, and in September 1957, on the time-saving, transpolar "great circle route," across the Arctic Ocean to Northern Europe. Many of Pan Am's regular business travelers chose the DC-7C over the Boeing 377 simply because it saved at least one hour on most transatlantic routes. See "Aviation Evolutions: The Jim Lund 1:72 Scale Model Airplane Collection", which features more than 200 models, on display, pre-security, in the Aviation Museum. http://bit.ly/AviationEvolutions Image: Pan American World Airways postcard, Douglas DC-7C, c. 1956.
