Rather, it was a deliberate act carried out by a captain who knew exactly what he was doing, says Canadian Air crash investigator Larry Vance.
In it he concluded Captain Shah killed the passengers and crew by depressurising the aircraft while he was on the pilot's long oxygen supply.
For more than four years the world has grappled with questions over how the Boeing 777 airliner vanished into thin air en route to Beijing from Kuala Lumpur.
"He was killing himself; unfortunately, he was killing everybody else on board, and he did it deliberately."
The wreckage uncovered so far may be further evidence that the pilot actually had control and that it was not a high speed crash.
The debate over whether Shah was still alive when MH370 began its final descent is part of this larger argument - we've seen that argument play out both ways, with some claiming that debris analysis shows an uncontrolled descent into the ocean, while others claim that the evidence favors a controlled descent.
He told the programme that as the aircraft went across Thailand and Malaysia, it ran down the border, going in and out of the two countries.
The media section on the government's website has not been updated since 2016, with the last post on its homepage written in January this year about the search. And after two months of thinking about it, I finally got the answer - somebody was looking out the window.
"It might [have been] a long, emotional goodbye or a short, emotional goodbye to his hometown".
He added that if he were hired to make Boeing 777 disappear, he would "do the exact same thing".

Several family members of MH370 victims told CBS the theories about Shah are nothing new.
Shah was aided, unwittingly, in his suicide mission by his co-pilot, Fariq Abdul Hamid, according to The Evening Standard. There were rumors that Zaharie's marriage was ending and that he downed the plane after learning that his wife was about to leave, the news site said.
Many possible motives were theorised after the plane vanished, with claims that Shah brought down the plane in a fit of rage after hearing his wife was leaving him, as well as rumours that he hijacked his own plane in protest of the jailing of then-Malaysian opposition leader Anwar Ibrahim, being floated in the press.
Ocean Infinity CEO Oliver Plunkett said the company's technology had performed "exceptionally well" and collected "significant amounts of high-quality data".
