As the mystery behind the resting place of missing Malaysia Airlines Flight MH370 remains unsolved, a U.S.-based truth-seeker claimed the plane crashed off the eastern coast of Vietnam. The Boeing 777-200 disappeared March 8, 2014, with 239 people on board while on its way from Kuala Lumpur to Beijing.

Yao Ming, who reportedly studies satellite engineering at Stanford University, told the Daily Express he had coordinates of a location which was not where the initial search for the plane was conducted. Investigators looking into the plane's disappearance believe it went down in a remote location in the southern Indian Ocean. However, a multimillion-dollar search of the area for over three years yielded no concrete clues as to the plane's whereabouts.

"One very possible outcome which has been instantly disregarded are the coordinates off the Vietnamese coast at N14.9, E109.15 where MH370 was apparently tracked," Yao was quoted as saying. He also said he contacted Daniel Boyer, an MH370 hunter from the United Kingdom who believes, based on satellite images, that the plane crashed in the jungle northwest of Cambodia's capital.

"Using simple algebra I am able to plug in distances from the alleged coordinates to Daniel Boyer's crash coordinates with the time frame given by air traffic control," Ming said. "From my calculations, if the ignored air traffic control coordinates are correct, the jetliner flew roughly 230-250 miles within a time frame of 33 minutes, giving an average ground speech of about 460-470mph in this time frame and an exact distance from both coordinates.

"The average speed of a Boeing 777 in its last half hour of flight matches the exact needed speed to get from these coordinates within air traffic control's time frame."

However, these claims cannot be independently confirmed.

Two extensive search operations, one led by the tripartite team from Australia, Malaysia and China, and another by U.S.-based seabed exploration company Ocean Infinity, turned out to be fruitless.

The biggest lead in the investigation came when a plane flaperon was found by villagers on the French island of Réunion. Possible pieces of wreckage had also turned up on the shorelines of Africa, Mozambique and Mauritius, investigators said. Another report said 27 pieces of wreckage found were believed to be from MH370, though only three were confirmed as parts that actually belonged to the doomed jetliner.

In July 2018, Malaysia released a report stating Flight MH370 deviated from its path "not because of anomalies in the mechanical system. The turn back was made not under autopilot but under manual control.” However, it added that a “third-party interference” couldn’t be ruled out.

Since the plane disappeared, there have been several conspiracy theories suggesting what might have happened to the jet. While some claimed the pilot of the plane planned a "murder-suicide," others said the plane was hijacked. There were also theories that lithium batteries on board the plane exploded, causing a fire.

In a recent bizarre claim, Noel O’Gara, who has spent four years looking for answers, said the jetliner was mistakenly shot down by Malaysian military. He said five people claimed to have witnessed the final moments of the jet and their accounts could shed light onto its whereabouts. However, none of the conspiracy theories have been confirmed.
