The Douglas DC-9 (later known as the McDonnell Douglas DC-9), was a narrow-body jet airliner with a T-tail and two engines mounted on either side of the rear end of the fuselage. It was one of the most successful airliners of all time; across all variants, including the McDonnell Douglas MD-80 series, the McDonnell Douglas MD-90, and the Boeing 717, a total of more than 2400 DC-9's were built over the course of more than 40 years.


History

Douglas Aircraft began initial design work for what would ultimately become the DC-9 in 1962. The aircraft was especially designed to operate effectively at smaller regional airports with smaller terminals and shorter runways, explaining its narrow body, relatively small wings, and rear mounted engines.

The first production aircraft made its maiden flight on February 25, 1965, and after receiving its airworthiness certification, the plane entered service with Delta Airlines on December 8.

The plane was always intended to have stretched variants that could carry more passengers; in addition to the initial model, designated the DC-9-10 series (with the -15 variant being the most common), the -20, -30, -40, and -50 stretched variants were rapidly introduced. Three final variant series were produced under different names, with the -80 and -90 being renamed to the McDonnell Douglas MD-80 and the McDonnell Douglas MD-90 to make them sound like newer airplanes, and the -95 variant being renamed the Boeing 717 after Boeing bought McDonnell Douglas in 1997.

In addition, there were four variants of the military version of the DC-9, designated the C-9: the C-9A Nightingale used by the Air Force, and the C-9B Skytrain II, used by the Naval Reserve and the Marine Corps, the VC-9C, used by US presidents and vice-presidents as Air Force One and Air Force Two, and the C-9K model, two of which were built for export to Kuwait.

The last Boeing 717 rolled off the production line in 2006.
