McDonnell Douglas DC-9 Series 40

The McDonnell Douglas DC-9 is a single-aisle airliner designed and manufactured by the Douglas Aircraft Company. The design aimed to create a smaller variant akin to the larger DC-8, which had significantly greater size and capacity. The initial design featured two rear-mounted Pratt & Whitney JT8D turbofans under the T-tail, facilitating a cleaner wing design and incorporating airstairs into the fuselage. In the late 1960s, Douglas introduced the Series 30, specifically the DC-9-31 model, for a competition. Successfully submitted, it was purchased by Eastern Airlines in early 1967 due to its improved performance with the stretched fuselage and wings. With the Series 40, Douglas further extended the fuselage to accommodate an additional 20 passengers.
