Crash of EgyptAir Flight 990

Date: October 31, 1999 • Location: Nantucket County, United States

All 217 people on board EgyptAir Flight 990 perished when the aircraft suddenly crashed into the Atlantic Ocean off the coast of Nantucket, Massachusetts.

EgyptAir Flight 990 was a scheduled flight from Los Angeles International Airport to Cairo International Airport, with a stop at John F. Kennedy International Airport, New York City. On October 31, 1999, the Boeing 767 operating the route crashed into the Atlantic Ocean about 60 miles (100 km) south of Nantucket Island, Massachusetts, killing all 217 passengers and crew on board, making it the deadliest aviation disaster for EgyptAir. Since the crash occurred in international waters, it was investigated by the Egyptian Ministry of Civil Aviation's Civil Aviation Agency (ECAA) and the American National Transportation Safety Board (NTSB) under International Civil Aviation Organization rules. Since the ECAA lacked the resources of the NTSB, the Egyptian government asked the American government to have the NTSB handle the investigation.
