I apologize for the 32-minute delay, this DC-8-55CF Japan Airlines was a combi that operated for Japan Airlines from 1960 to 1972. It has a cargo door to transport cargo and passengers. Wiki: DC-8 Jet Trader: Douglas approved the development of freighter versions of the DC-8 in May 1961, based on the Series 50. An original plan to fit a fixed bulkhead separating the forward two-thirds of the cabin for freight, leaving the rear cabin for 54 passenger seats, was soon replaced by a more practical one to use a movable bulkhead and allow anywhere between 25 and 114 seats with the remainder set aside for cargo. A large cargo door was fitted into the forward fuselage, the cabin floor was reinforced, and the rear pressure bulkhead was moved by nearly 7 feet (2.1 m) to make more space. Airlines could order a windowless cabin, but only United did, ordering 15 in 1964. The DC-8F-54 had a maximum takeoff weight of 315,000 pounds (142,880 kg) and the DC-8F-55 325,000 pounds (147,420 kg). Both used 1,the following plane will be a Boeing 707-321B Pan Am flight 812 .
