From mind control, to the missing Malaysian airways flight MH370, here are the top 10 conspiracy theories.
The experts theorized that Shah depressurized the plane, knocking out anyone aboard who wasn't wearing an oxygen mask.
That allowed the aircraft to stay off of military radar - and it was a success, says Hardy, since no military aircraft were sent up to dispatch the craft.
Zaharie and co-pilot Fariq Abdul Hamid were prime suspects in the plane's disappearance from the beginning.
A panel of five, with expertise across a range of aviation disciplines, appeared on 60 minutes Australia to shed light on the growing consensus.
"60 Minutes Australia" brought together several aviation experts to discuss the crash and they believe the pilot, Zaharie Shah, slammed the plane into the Indian Ocean on objective, according to CBS News.
Former senior investigator with the Transportation Safety Board of Canada, Larry Vance, this week unveiled a new book MH370: Mystery Solved, and said the pilot "was killing himself" and took the aircraft to the most remote place possible so it would "disappear".
Zaharie's suspected suicide might explain an oddity about the plane's final flight path: that unexpected turn to the left. "It just goes to show that the pilot, that the captain in charge, had been thinking about this, may have planned this in advance, and did one of the most heinous acts in modern commercial aviation".More news: Gas Prices Rise 1.6 Cents In Chattanooga

Senior Boeing 777 pilot and instructor Simon Hardy told 60 Minutes on Sunday he believed the pilot deliberately flew the aircraft over his hometown of Penang for an "emotional goodbye".
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.
Hardy said the maneuvers were clearly deliberate.
"I spent a long time thinking about what this could be, what technical reason is there for this?" he said. He also disclosed that "If you were commissioning me to make a 777 disappear, I would do exactly the same thing".
"It might be a long, emotional goodbye or a short, emotional goodbye to his hometown".
Ocean Infinity started a new search for MH370 January 22.
The company has 90 search days to look for the plane, which has been spread over several months.
The panel also concluded, based on physical evidence recovered by official investigators, that the airplane did not strike the water in a sharp dive as earlier reports suggested but was likely controlled until the end, crashing far from shore and outside the earlier search area.
