The Malaysian Airlines plane - carrying 239 people - vanished en route from Kuala Lumpur to Beijing on March 8, 2014, above the Indian Ocean.
Investigators are still searching for the aircraft, but these findings raise the possibility that one of the greatest aviation mysteries in modern history may not have been a catastrophic accident, but instead a possible mass murder-suicide.
Former Australia Transport Security Bureau head Martin Dolan added: "This was deliberate, this was deliberate, and it was finished over an prolonged time frame".
Hardy claims that Shah piloted the aircraft along the Malaysia and Thailand border-criss-crossing along the way to evade detection from either side.
"So each of the controllers aren't bothered about this mysterious plane".
A panel of five, with expertise across a range of aviation disciplines, appeared on 60 minutes Australia to shed light on the growing consensus. And after two months of thinking about it, I finally got the answer - somebody was looking out the window.
"[Shah] was killing himself; unfortunately, he was killing everybody else on board, but he did it deliberately", senior investigator with the Transportation Safety Board of Canada, Larry Vance, said on the Sunday night program.
Shah somehow managed to cut all communication systems and then dip in and out of Malaysian and Thai airspace and eventually went over his own hometown, Penang, Boeing 777 pilot and instructor Simon Hardy said.
John Dawson, a lawyer who represented nine families from MH370 and MH17, which was shot down by rebels in Ukraine in July 2014, said: "In MH370, you have the pilot flying between Malaysia and Beijing who turns back the aircraft".
It is noted that before the crash the pilot had the plane over his hometown. In the event you had been commissioning me to do that operation and attempt to make a 777 disappear, I'd do precisely the identical factor.
Most of the wreckage from the airliner has never been found and bodies have never been recovered.
"That plane has most likely depressurised, the individuals died of asphyxiation, it was premeditated homicide".
Ocean Infinity started the search on January 22, following a failed $200 million search for the plane.
The investigation is anticipated to finish in mid-June however these on the TV present stated they feared MH370 could by no means be discovered.
