On March 8, 2014, a Malaysia Airlines Boeing 777-200ER departed from Kuala Lumpur with 227 passengers and 12 crew members. It departed at 12:41 am (1441 GMT), and was due in Beijing at 6:30 am (2230 GMT) that same day. It hasn’t been seen since. This report attempts to debunk some of the theories about that disappearance and make a new assertion about what might have befallen the passengers and crew of that ill-fated flight. Flight MH 370.

Conspiracy theories don’t hold water because they ignore certain things that have to happen in conjunction with those events in order for them to be correct. What all the theories about the disappearance of this plane leave out are the important aircraft systems that would react (or try to) in any mishap involving the plane. Here are a few.

The Cabin Emergency Depressurization Oxygen System. The “Rubber Mask Jungle” drops if the cabin pressure drops below a certain level – typically at 14,000 feet. The pilots can deploy the system manually or leave it set on automatic. But the pilots cannot turn it off.
