The original project of the Douglas DC-7 was a civil version of the military transport C-74 'Globemaster 1' but never reached the market introduction despite a first order of 26 aircraft from Pan American World Airlines. As the limited military production run increased the cost per civilian aircraft Pan American canceled its order. Douglas then dropped the DC-7 project. The DC-7 designation was later used for a completely different civilian airliner project in the early 1950s, having no relationship to the C-74. |
