DC-9-40

The McDonnell Douglas DC-9-40 was a stretched and enhanced variant of the DC-9 family, introduced in 1968 to increase passenger capacity while maintaining efficiency. Powered by two Pratt & Whitney JT8D-9 or JT8D-11 turbofan engines, each producing 14,500 lbf (64 kN) of thrust, it offered dependable performance for short- to medium-haul operations. The DC-9-40 featured a fuselage stretch of 1.93 meters (6 feet 4 inches) over the DC-9-30, accommodating up to 125 passengers in a typical two-class configuration. With a maximum takeoff weight of 52,390 kg (115,500 lbs), a cruising speed of 880 km/h (475 knots), and a range of about 2,800 km (1,500 nautical miles), it provided airlines like SAS, Finnair, and Texas International with a reliable, higher-capacity jet.
