Historical Snapshot

DC-7 Transport

The DC-7 was the last of the Douglas propeller-powered transports. Introduced in May 1953, it entered service with American Airlines in November 1953. It was the first commercial transport able to fly nonstop westbound across the United States against the prevailing winds.

The extended-range DC-7C, or the ”Seven Seas,” lived up to its name because it could fly 110 passengers anywhere in the world.

Douglas built 338 DC-7s and delivered the last in 1958. Most DC-7s were modified as freighters or scrapped. Some were kept for air racing, aerial firefighting and satellite tracking.
