Swissair Flight 111 was a scheduled international passenger flight from John F. Kennedy International Airport in New York City, United States, to Cointrin Airport in Geneva, Switzerland. The flight was also a codeshare flight with Delta Air Lines. On 2 September 1998, the McDonnell Douglas MD-11 operating this flight crashed into the Atlantic Ocean southwest of Halifax Stanfield International Airport at the entrance to St. Margarets Bay, Nova Scotia, Canada, killing all 215 passengers and 14 crew members on board. The crash site was 8 kilometres (5 mi; 4 nmi) from shore, roughly equidistant from the small fishing and tourist communities of Peggys Cove and Bayswater. It is the deadliest accident in Swissair history, the deadliest involving the MD-11, and the second-deadliest aviation accident in Canada, behind Arrow Air Flight 1285R.
The search and rescue response, crash recovery operation, and investigation by the Government of Canada took more than four years and cost CA$57 million. The investigation carried out by the Transportation Safety Board of Canada (TSB) concluded that flammable material used in the aircraft's structure allowed a fire to spread beyond the control of the flight crew, resulting in the crash of the aircraft. Several wide-ranging recommendations were made, which were incorporated into newer US Federal Aviation Administration (FAA) standards.
