Sabena Flight 548 was a Boeing 707-329 flight operated by Sabena that crashed en route from New York City to Brussels, Belgium, on February 15, 1961. The flight, which had originated at Idlewild International Airport, crashed on approach to Zaventem Airport, Brussels, killing all 72 people on board and one person on the ground. The fatalities included the entire United States figure skating team, who were travelling to the World Figure Skating Championships in Prague, Czechoslovakia. The precise cause of the crash remains unknown; the most likely explanation was thought to be a failure of the mechanism that adjusted the tail stabilizer.This was the first fatal accident involving a Boeing 707 in regular passenger service; it happened 28 months after the 707 airliner was placed into commercial use. It remains the deadliest plane crash to occur on Belgian soil.
