Book excerpt: The McDonnell Douglas DC-10 three-engine jet is one of the most distinctive wide-bodied aircraft and since the early 1970s has been operated by many airlines on medium- and long-distance routes throughout the world. Successfully flying passenger service for over 40 years, the DC-10 currently still flies for FedEx in an airfreight delivery role. Filled with design and construction information, background history, technical data, and rare images, this book describes the exciting story of this aviation legend as flown by such current and past airlines as Aeroflot, American, Delta, Eastern, KLM, Lufthansa, Northwest, Pan Am, Qantas, SAS, Swissair, United, and many others. Also, the US Air Force has been flying the KC-10 Extender aerial-refueling tanker variant since the early 1980s. Coverage of the follow-on MD-11 series of aircraft is also included.
