As the mystery about Malaysia Airlines Flight MH370 deepens, a conspiracy theorist claimed to have spotted the missing plane on Google Maps off the coast of Padang, Indonesia. However, a volunteer investigator debunked the report saying it was another plane coming in to land above the water.

The image of a plane on Google Maps was shared on with the conspiracy theorist claiming the jetliner was spotted during a computer search of waters where Flight MH370 may have gone down. The four-year-long investigation into the disappearance of the plane has left more questions than answers.

"Just putting this out there, what if this was the MH370 after all this time?" the theorist wrote. "Some will say it's just an aircraft coming in for landing caught on satellite, some may say this is just a bogus post... But just imagine the aircraft came in for a slow soft water landing, in calm waters which is below the radar and they knew it was there for a rescue job."

One of the comments on the post read: "Yikes, it's not a bogus post, I just checked and it was there. And it ain't coming into land, if you look closely, it looks like it's upside down?"

However, Andre Milne — founder of military technology firm Unicorn Aerospace — denied the claims saying it was "a commercial airliner."

“It has just descended to an altitude of approximately 10,000 feet and is preparing to land at Minangkabau International Airport that shortly after this image was captured then banked left to make final approach for a safe landing on runway 34,” Milne told the Daily Star.

Flight MH370 went missing on March 8, 2014, with 239 people on board while on its way from Kuala Lumpur to Beijing. A multimillion-dollar search for over three years yielded no concrete clues as to the plane's whereabouts.

This latest Google Maps claim is not the first to come out since the plane's disappearance. There have been several instances in the past when people worked on similar theories to find the missing plane. Some independent searchers also physically traveled to locations where the plane's debris may have washed up. One such searcher had collected debris, some of which are believed to be from the missing Boeing 777-200.

Since the plane went missing, there have been several theories that emerged related to the cause of the plane's mysterious disappearance. Some theorists claimed MH370 was shot down by military forces. While some claimed the plane was accidentally shot down during a joint U.S.-Thai military exercise, others blamed North Korea of doing so. Some theorists claimed the jet entered another Bermuda Triangle, also known as the Devil’s Triangle, located in Asia in the Indian Ocean.

The most latest theory suggests Flight MH370 was most likely brought down by a stowaway on board the jet. The new theory came just weeks after Malaysia said in its report that they have not ruled out the possibility of a hijack. The 449-page report released on July 30 sparked condemnation from the families of those on board the jet as they accused the Malaysian government of a massive cover-up.

Meanwhile, an expert recently claimed the Flight MH370 will be found just outside the area that was searched since the plane went missing.
