Study: MH370 pilot turned off oxygen supply, ditched plane into sea

The death of MH370 passengers was due to oxygen starvation experts suggested Tuesday following a new study of the disaster, according to the British daily news website Mirror.

All 239 people lost consciousness up to four hours before the Malaysia Airlines Boeing 777 disappeared as the pilot deliberately depressurized the cabin, the study suggested.

Although, oxygen masks would have dropped down automatically from above the seats, their supply was limited to just 20 minutes.

Passengers who were asleep and those who were unable to grab a mask lost consciousness a few minutes after the pilot’s move.

The study also suggested that the pilot locked his co-pilot outside of the cockpit before executing “his master plan” and performing a controlled ditching in the sea, which would explain why no debris has been found because the plane landed and sank in one piece.

Earlier this year, the Australian Transport Safety Bureau (ATSB) also concluded that passengers may have died from hypoxia.

So far, searchers have found no trace of the plane or its passengers, making the case probably the biggest mystery in aviation history.

The Malaysia Airlines plane went missing on March 8, sparking an international search for the wreckage.
