The aircraft, a seven-year-old McDonnell Douglas MD-11, serial number 48448, registration HB-IWF, was manufactured in 1991, and Swissair was its only operator. It bore the title of "Vaud", in honor of the Swiss canton of the same name. The cabin was configured with 241 passenger seats. First and business class seats were equipped with in-seat in-flight entertainment (IFE) systems from Interactive Flight Technologies. The aircraft was powered by three Pratt & Whitney 4462 turbofan engines and had logged over 36,000 hours before the crash. The in-flight entertainment system was the first of its kind equipped on the plane. It allowed the first and business class passengers to browse the web, select their own movies and games, and gamble.
