Experts theorized the Boeing 777 flew off course for several hours before running out of fuel over the southern Indian Ocean.

6 Missing Flights Mysteries Other than MH370

The disappearance of MH370 is not an isolated incident. The history is replete with many such unsolved mysteries of missing flights.

EgyptAir Flight 804

On May 19, 2016, EgyptAir Flight 804, carrying 66 passengers from Paris to Cairo, plunged into the Mediterranean Sea, leaving investigators puzzled. Though the digital flight data and cockpit voice recorders were recovered, the mystery persisted. Initial speculation centered on terrorism, but France’s civil aviation bureau later concluded that a rapidly spreading fire in the cockpit caused the crash. Smoke was detected just before the plane disappeared from radar, and the aircraft took an unusual turn, indicating a descent to vent smoke. A subsequent investigation linked the crash to a pilot smoking in the cockpit and a leaking oxygen mask.
