DC-8 Airliner

Douglas DC-8 (sometimes McDonnell Douglas DC-8) is a narrow-body airliner built by the American Douglas Aircraft Company. After losing the May 1954 US Air Force tanker competition to the Boeing KC-135, Douglas announced in July 1955 its derived jetliner project. In October 1955, Pan Am made the first order along with the competing Boeing 707, and many other airlines followed. The first DC-8 was rolled out in Long Beach Airport on 9 April 1958 and flew for the first time on 30 May. FAA certification was achieved in August 1959 and the DC-8 entered service with Delta Air Lines on September 18.

Operational use

From 17 March 1924, the pilots practiced in the prototype which served as a training aircraft.[6] On 6 April 1924, the four expedition aircraft, named Boston, Chicago, New Orleans and Seattle,[N 2] departed Sand Point, Washington, near Seattle, Washington. [N 3]Seattle, the lead aircraft, crashed in Alaska on 30 April. The other three aircraft with Chicago assuming the lead, continued west across Asia and Europe relying on a carefully planned logistics system, including prepositioned spare engines and fuel caches maintained by the U.S. Navy and Coast Guard, to keep the aircraft flying

The DC-8-71, DC-8-72, and DC-8-73 were straightforward conversions of the -61, -62 and -63 primarily involving the replacement of the JT3D engines with more fuel-efficient 22,000 lb (98.5 kN) CFM56-2 high-bypass turbofans with new nacelles and pylons built by Grumman Aerospace and fairing of the air intakes below the nose. The DC-8-71 achieved the same end but required more modification because the -61 did not have the improved wings and relocated engines of the -62 and -63. Maximum takeoff weights remained the same, but there was a slight reduction in payload because of the heavier engines. All three models were certified in 1982 and a total of 110 60-Series DC-8s were converted[15] by the time the program ended in 1988. DC-8-70 conversions were overseen by Cammacorp with CFMI, McDonnell Douglas, and Grumman Aerospace as partners. Cammacorp was disbanded after the last aircraft was converted

The Douglas World Cruiser (DWC) was developed to meet a requirement from the United States Army Air Service for an aircraft suitable for an attempt at the first flight around the world. The Douglas Aircraft Company responded with a modified variant of their DT torpedo bomber, the DWC.
