Swissair Flight 111 Investigation Part 1

Swissair Flight 111 (SR-111, SWR-111) was a Swissair McDonnell Douglas MD-11 on a scheduled airline flight from John F. Kennedy International Airport in New York City, United States to Cointrin International Airport in Geneva, Switzerland. This flight was also a codeshare flight with Delta Air Lines.
On September 2, 1998 the aircraft used for the flight, registered HB-IWF, crashed into the Atlantic Ocean southwest of Halifax International Airport at the entrance to St. Margarets Bay, Nova Scotia. The crash site was 8 kilometres (5 mi) from shore, roughly equidistant between the tiny fishing and tourist communities of Peggys Cove and Bayswater. All 229 people on board were killed.[1]
The resulting investigation by the Transportation Safety Board of Canada (TSB) took over four years and cost CAD$57 million (at that time approximately US$39 million).[2] The organization concluded that flammable material used in the aircraft’s structure allowed a fire to spread beyond the control of the crew, resulting in the loss of control and crash of the aircraft.
