Douglas DC-8

The Douglas DC-8 is a long-range four-engine jetliner that entered service in 1959 as Douglas Aircraft's answer to the Boeing 707. Designed for both domestic and intercontinental routes, the DC-8 featured a swept-wing design, four underwing-mounted turbofan engines, and a fuselage cross-section that became standard for narrow-body jets. The family evolved through multiple series: the original DC-8-10/20/30/40/50 variants featured different engines and ranges, while the stretched DC-8-60 series (introduced 1967) added up to 11 meters of fuselage length. The DC-8-70 series (1980s) retrofitted -60 airframes with modern CFM56 turbofan engines for improved efficiency. DC-8s served major airlines worldwide and pioneered transoceanic jet service. A total of 556 aircraft were built between 1958 and 1972. Many DC-8-50s continue operating as freighters, testament to the design's durability and cargo capacity.
