The engine of missing Malaysia Airlines Flight MH370 has been allegedly spotted in the Cambodian jungle on Google Maps, pilot Daniel Boyer claimed. The British aviation expert had previously claimed to have located the missing plane fuselage, tail and the cockpit in the same area.

Boyer told Daily Star over the weekend he believed he knew the exact location of the engine and urged authorities to investigate his claims. Boyer reportedly showed images to the media outlet, which featured some white object lying in the Cambodian jungle 60 miles west of Phnom Pen. However, the claim could not be confirmed.

According to Boyer, the object measured 14.3-foot wide and 9.1-foot long, similar to the size of a standard passenger aircraft engine.

“I’m gobsmacked, this area has not yet been searched. This is a massive discovery. It needs to be investigated,” he told the media outlet.

The latest claim comes as British investigator Ian Wilson aborted his search mission in the Cambodian jungle due to the dangers on the path. Wilson had allegedly spotted the plane on Google Earth images, and, despite many saying he had mistaken it to be some other passenger plane, set out to locate the plane to prove his claim.

Meanwhile, another truth-seeker told Daily Star the theory that MH370 crashed in the Cambodian jungle was "not credible."

"If MH370 is ever found, it will be found in the Southern Indian Ocean somewhere in the vicinity of where the official search was conducted," the author of “MH370: Mystery Solved,” Larry Vance, said. Vance said the aircraft was in the Southern Indian Ocean.

“Even if it had not already been proven that MH370 flew for many hours and then crashed into the Southern Indian Ocean, anyone with even rudimentary knowledge of crash dynamics would know that a B777 – in fact, any airplane – cannot crash into a jungle and leave a footprint that looks like what is shown in his image,” he said, dismissing Wilson's claims.

Flight MH370 went missing March 8, 2014, with 239 people on board while on its way from Kuala Lumpur to Beijing. Over the last four years, several efforts have been made to find the wreckage of the plane; however, none have succeeded. A multimillion-dollar search operation in a remote part of the southern Indian Ocean also could not yield concrete clues about the plane's whereabouts.

Since the plane disappeared, many conspiracy theories have emerged. Some claimed the pilot crashed the plane in a "death-dive," while others hinted at a possible hijack. None of the theories so far were confirmed by authorities.

Last week, an amateur searcher claimed to have spotted the Boeing 777-200's wreckage off the coast of Thailand and Myanmar on Google Maps. Satellite image taken from Google Earth by the United Kingdom-based sleuth, who works in aviation security, allegedly pointed at an object appearing to be shaped like a large passenger plane, giving rise to the theory it could be the missing plane. However, this claim was not confirmed.

The biggest lead in the investigation came when a plane flaperon was found by villagers on Réunion Island. Investigators said in the report 27 pieces of wreckage were believed to be from MH370, though only three have been confirmed as parts belonging to the plane.
