The McDonnell Douglas Story by Douglas J. Ingells, Aero Publishers, Inc., 1979.
Proposed wide-cabin jet transport under study in Long Beach was designated the DC-X-200. A twin-engine aircraft, the DC-X-200 was proposed as a replacement for narrow-cabin short-to-medium range jetliners. As envisioned by McDonnell Douglas engineers, the twin jet would carry about 200 passengers in a cabin almost 19 feet wide, same as the DC-10. Fuselage would be 140 feet long, and wingspan would be 150 feet. Tail height would be 52 feet. Advances in the DC-X-200 would include a supercritical wing and advanced high-lift system. DC-X-200 would offer considerable improvement over narrow-cabin jets in terms of fuel economy, passenger comfort, and cost of operation.
The DC-X-200, or Model D-969N-18D/18F, was a smaller aircraft that was proposed when the DC-10 Twin was rejected by airlines as being too large and too expensive to operate. Airline surveys in 1972-1973 indicated that they were more interested in a wide-bodied twin with 180 to 200 passenger capacity. The aircraft was designed to compete against the Airbus A200B and replace the larger Douglas DC-9 and Boeing 727 aircraft.

The DC-X-200 was aimed at the then airline capacity needs, with interior arrangements in a mixed class version for 18 first class passengers and 180 economy class, for a total 198. There was also a high density seating arrangement for a total of 226 passengers.
The cockpit, forward fuselage section, aft fuselage section were identifical to the DC-10. The DC-X-200 would differ in wings and engines to the DC-10. The supercritical wing would be brand new based on the development of the YC-15 Advanced Medium STOL transport. It would allow higher cruise speeds while at the same time having greater lift potentinal in the slow speed range. Greater lift would allow the DC-X-200 to operate at shorter airfields in smaller communities.
