i will highly appreciated to Up-vote this build since it hard to build :) [] The McDonnell Douglas MD-11 is an American three-engine medium- to long-rangewide-body jet airliner, manufactured by McDonnell Douglas and, later, by Boeing Commercial Airplanes. Based on the DC-10, it features a stretched fuselage, increased wingspan with winglets, refined airfoils on the wing and smaller tailplane, new engines and increased use of composite materials. Two of its engines are mounted on underwing pylons and a third engine at the base of the vertical stabilizer. It also features a glass cockpit that decreases the flight deck crew to two from the three required on the DC-10 by eliminating the need for a flight engineer.
