Title: Douglas DC-7 The DC-7 was prompted by an American Airlines requirement for a competitor to the Lockheed Super Constellation. Essentially a stretched DC-6 but using the Wright Turbo-compound engines used in the Constellation, the DC-7 first flew in 1953. 338 examples of three main versions were manufactured. This title contains three flight manuals for the Douglas DC-7C (the final DC-7 version designed for the non-stop North Atlantic route, with a slightly lengthened fuselage, increased span wing and more powerful engines.) The files have been scanned from the original flight manuals and retain any colour pages.
