MH370 was flying 239 people from Kuala Lumpur to Beijing on March 8, 2014, when it suddenly disappeared. The Boeing 777 aircraft last communicated with air traffic control at 1.19am when the plane was flying over the South China Sea, before vanishing from civilian radar screens. Mr Shah was in control of the plane that night and has come under scrutiny over the past five years, over claims he may have crashed MH370 on purpose.
Now, award-winning journalist Ean Higgins has released a new book in an attempt to uncover what went wrong.
The text, titled: “The Hunt for MH370”, was published on February 26, 20019, points the finger at Mr Shah.
Mr Higgins explained during an interview how he believes the event could have played out.
He told ABC News (Australia) on March 8: “What we believe happened is, 40 minutes into the flight, Captain Shah depressurised the aircraft.
“You can just press a button above your head and the aircraft will cut the oxygen.
’We think he also tripped the circuit of the lights in the passenger cabins, to make it dark.
“He then flew on for about another six hours.
“I’m of the view there is a possibility the pilot was flying until the end.”
It is not the first time claims of this nature have surfaced.
It was previously claimed Mr Shah made a “final goodbye gesture” during the doomed flight.
Analysis of radar and satellite data showed the plane suddenly changed course and flew back across Malaysia before turning south of Penang and then towards the southern Indian Ocean.
This change may have been made deliberately by Mr Shah in an attempt to get a glimpse of his hometown before crashing, it was claimed.
Simon Hardy, a UK aviation expert, revealed to investigators at Australia’s “60 Minutes” his theory, by running a flight simulation.
He said last year: “If you look very carefully, you can actually see the plane dips to the left, before starting a long turn to the right, followed by another left turn.
“So I spent a long time thinking about what technical reason there could be for this.
“After three months of thinking, I finally got the answer – someone was looking out of the window.
“It may have been a long-emotion final goodbye or a short goodbye to Mr Shah’s hometown of Penang.”
In 2016, Mr Shah also faced backlash after Australian officials confirmed he had practiced a route where the plane is said to have vanished using an in-flight simulator he had built at home.
A statement read: “The simulator information shows only the possibility of planning.
“It does not reveal what happened on the night of its disappearance nor where the aircraft is located.
“For the purposes of defining the underwater search area, the relevant facts and analysis most closely match a scenario in which there was no pilot intervening in the latter stages of the flight.”
However, this is just one of many theories over what happened to MH370.
