Passengers on flight MH370 died of oxygen starvation hours before the pilot performed a controlled ditching in the Indian Ocean, according to a new study into the disaster.
Analysis by a veteran air accident investigator suggests that all 239 people lost consciousness up to four hours before the Boeing 777 disappeared beneath the waves.
The most likely scenario is that pilot Zaharie Ahmad Shah deliberately depressurised the cabin, thereby depriving those on board of air, the research concludes.
Although oxygen masks would have dropped down automatically from above the seats, their supply was limited to just 20 minutes.
Those unable to grab a mask, including sleeping passengers, would have passed out within the space of a few minutes.
The entire 'ghost plane' - including her cabin crew whose air supply is only marginally longer, would have slipped into a coma and died shortly after from oxygen starvation.
Ahmad Shah, who locked his co-pilot out of the cockpit, survived long enough - either by repressurising the aircraft or from breathing his own, more extensive air supply - to evade radar and 'execute his master plan', researchers have concluded.
He then performed a controlled ditching in the sea, which would explain why no debris has been found because the plane landed and sank in one piece.
