The McDonnell Douglas DC-10 is a three-engine wide-body jet airliner manufactured by McDonnell Douglas. It features two turbofan engines mounted on underwing pylons and a third engine at the base of the vertical stabilizer. The DC-10 has range for medium- to long-haul flights, capable of carrying a maximum of 380 passengers. The DC-10 was intended as a successor to the McDonnell Douglas's DC-8 for long-range operations, using a wide-body layout to greatly increase the capacity of the aircraft. More powerful engines allowed it to be powered by three engines, the minimum allowed at that time for long overwater flights, which reduces maintenance costs relative to a four-engine design. Lockheed also saw this niche as an ideal place to reenter the commercial airliner market with their very similar L-1011 TriStar. Although the L-1011 was more technologically advanced, the DC-10 would go on to outsell the L-1011 by a significant margin, due to the L-1011's higher price and delayed entry in the market.
