It may already be confirmed of the real cause of Malaysia Airlines 370 crash. It may be considered that a simple mistake may result in a fatal plane crash.
According to New York Post, the cause of the Malaysia Airlines 370 may have been a simple bathroom break of the captain. This is one of the theories from "The Crash Detectives" which is a well-known book documenting and studying plane crashes and disasters.
The Malaysia Airlines 370 Boeing 777 took off from Kuala Lumpur 12:42am and it is bound for Beijing. It was a full flight with 227 passengers and 12 crew including those on the flight deck. The pilots of the ill-fated flight were Capt. Zaharie Ahmad Shah and First Officer Fariq Abdul Hamid.
After 25 minutes of the Malaysia Airlines 370 flight, Zaharie made contact with the traffic controllers that the flight was maintaining flight level 350. The jet was headed northeast at 35,000 feet flying over the South China Sea. At this point, everything is well.
Since the Malaysia Airlines 370 was already on auto-pilot, the pilots decided to go for what they call "biological break." While the captain was away from the flight deck, the first officer's role is to make contact with Vietnamese controllers in Ho Chi Minh. Malaysian traffic controller handed off Malaysia Airlines 370 1:19pm.
At this time Malaysia Airlines 370 suffered explosive decompression sucked the air out of the entire cabin which resulted in disaster. As this happened, Fariq has few seconds to put on his oxygen mask. At 35,000 feet above sea level, the air doesn't have enough oxygen to support the brain's ability to think and make decisions.
The Malaysia Airlines 370 was then left in the hands of the inexperienced first officer. This all happened as the Zaharie went out to do the toilet break. It is believed that Zaharie wasn't able to get back on the flight deck to take control of the flight.
As added by Mirror, this latest theory came about after finding no signs that both pilots were not suicidal. There is no physical evidence on Malaysia Airlines 370. At this time, the black boxes are yet to be found. This theory relating to the "biological break" may be the real reason behind the crash.
