  • Production262 Super 60 series built with 110 70 series conversions. In late 2002 approximately 82 Super 60s and 96 Super 70s were still in commercial service.

The fruitful DC-8 Super 60 aerial transports are extended improvements of the DC-8 Series 50. The Super 70s are Super 60s re-engined with Cfm56 high sidestep turbofans.

Douglas declared the DC-8 Super Sixty arrangement in April 1965. The principal, a DC-8-61, took to the skies shockingly on March 14 1966, emulated by the first flights of the DC-8-62 on August 29 1966 and the DC-8-63 on April 10 1967. The DC-8-61 varied from the prior DC-8-50 in having two fuselage plugs which expanded length by 11.18m (36ft 8in), expanding max seating ability to 259 (the biggest of any single path carrier before the 757-300) and underfloor cargo limit by 80%. Planned for residential operations, its max takeoff weight was indistinguishable to the DC-8-50.

The Super 62 was proposed for long go operations and emphasized just a humble 2.04m (6ft 8in) stretch contrasted with the Series 50, more prominent wing compass, updated motor nacelles and arches and essentially expanded fuel limit. The Super 63 in the mean time consolidated the DC-8-61's fuselage with the DC-8-62's wings. It was the last DC-8 variation in generation, and the last was conveyed in May 1972.

Mcdonnell Douglas started a re-engining project of Super 60 arrangement airplane with CFM International Cfm56 motors in the early 1980s, known as the Super 70 Series. The initially changed over airframe flew in August 1981. The Super 70 air ship are significantly quieter than their antecedents, with better mileage and more noteworthy extent.
