Following more refinements , in 1979 the DC-10 Super 60 was proposed in three distinct versions like the DC-8 . The DC-10-61 was designed to be a high-capacity medium-range aircraft . It would have a fuselage stretch of over the earlier DC-10 models , enabling it to carry 390 passengers in a mixed class or 550 passengers in an all-economy layout , similar to Boeing 's later 777-300 and Airbus A340-600 . Like the DC-8 , the series 62 was proposed for long-range routes . It would feature a more modest fuselage stretch of , along with an increased wingspan and fuel capacity . It would be capable of carrying up to 350 passengers ( mixed class ) or 440 passengers ( all-economy ) , similar to the later Boeing 777-200 or the Airbus A330-300 / A340-300 / 500 . Finally , the series 63 would have incorporated the same fuselage as the DC-10-61 as well as all the larger wing of the -62 . After high-profile accidents in the 1970s , such as Turkish Airlines Flight 981 and American Airlines Flight 191 , the trijet 's reputation was seriously damaged by doubts regarding its structural integrity . For these reasons , and due to a downturn in the airline industry , all work on the Super 60 was stopped
