EgyptAir Flight 990 Crash
EgyptAir Flight 990 (MSR990) was a regularly-scheduled Los Angeles-New York-Cairo flight.
On October 31, 1999, at around 01:50 EST, Flight 990 plummeted into the Atlantic Ocean, about 60 miles (97 km) south of Nantucket Island, Massachusetts, in international waters, killing all 217 people on board. The exact cause is disputed; Egyptian investigators concluded that the aircraft crashed as a result of mechanical failure, while U.S. investigators concluded the aircraft was deliberately crashed in an apparent suicide.
The National Transportation Safety Board determines that the probable cause of the EgyptAir flight 990 accident is the airplane's departure from normal cruise flight and subsequent impact with the Atlantic Ocean as a result of the relief first officer's flight control inputs. The reason for the relief first officer's actions was not determined. ”— National Transportation Safety Board
