The Douglas DC-8 (sometimes McDonnell Douglas DC-8) is an early long-range narrow-body jetliner designed and produced by the American Douglas Aircraft Company. Work began in 1952 towards the United States Air Force's (USAF) requirement for a jet-powered aerial refueling tanker. After losing the USAF's tanker competition to the rival Boeing KC-135 Stratotanker in May 1954, Douglas announced in June 1955 its derived jetliner project marketed to civil operators. In October 1955, Pan Am made the first order along with the competing Boeing 707, and many other airlines soon followed. The first DC-8 was rolled out in Long Beach Airport on April 9, 1958, and flew for the first time on May 30. Following Federal Aviation Administration (FAA) certification in August 1959, the DC-8 entered service with Delta Air Lines on September 18.DC-8 Series 61: The "Super DC-8" Series 61 was designed for high capacity and medium range. It had the same wings, engines and pylons as the -55, and sacrificed range to gain capacity. Having decided to stretch the DC-8, Douglas inserted a 240-inch (6.1 m) plug in the forward fuselage and a 200-inch (5.1 m) plug aft, taking overall length to 187 feet 4 inches (57.10 m). The added length required strengthening of the structure, but the basic DC-8 design already had sufficient ground clearance to permit the one-third increase in cabin size without requiring longer landing gear. The variant first flew on March 14, 1966, and was certified on September 2, 1966, at a maximum weight of 325,000 pounds (147,420 kg). Deliveries began in January 1967 and it entered service with United Airlines in February 1967. It typically carried 180–220 passengers in mixed-class configuration, or 259 in high-density configuration. A cargo door equipped DC-8-61CF was also available. 78 -61s and 10 -61CFs were built.
