The Douglas DC-9 is a twin rear engined single aisle jet airliner. The Douglas DC-9 was designed for frequent short flights mainly regional routes. The DC-9 was the first aircraft in this new family of narrow body airlines followed by the MD-80, MD-90 and MD-95/717.
The series 10 is the original DC-9 what was just the DC-9 at first. This version is 104.4ft long and had a maxium take off weight of 82,000lb. It had two Pratt & Whitney JT8D-7 engines, 137 of this model was built.
This series was designed for Scandinavian Airlines (SAS) to improve short field performance by having more powerful engines and improved wings, it also had a shorter fuselage then the -10 series.
662 series 30 aircraft where produced, these where to compete with Boeing's 737 single aisle twin engined jet. The first operator of this type was Eastern airlines in February 1967. There where three engine types used on the 30 series, the P&W JT8D-7 and JT8D--9 what produced 14,500lb of thrust or the JT8D-11 with 15,000lb of thrust. This model had a stretched fuselage by 14ft 9 inches and a increased wingspan of a little over 3ft.
The DC-9-40 was again a lengthened version with 6ft 6 inches added on. This version first entered service with Scandinavian Airlines (SAS) in March 1968,
The final series is the longest DC-9 produced, this had a 8ft 2 inch fuselage stretch and could seat up to 139 passengers. This started service in August 1975 with Eastern Airlines. A number of improvements where made to the -50 series, including a new cabin interior, more power full engines (JT8D-15 or 17, producing between 16,000lb and 16,500lb of thrust). They added new thrust reversers what rotated 22 degrees but later maintenance changes meant some had the same thrust reversers as the -30 and -40 series.
The C-9 was a military aero medical evacuation aircraft, it was the C-9A Nightingale for the USAF and the C-9B Sky Train II for the US Naval Reserve and Marine Corps. There where 48 of these built.
