A man described as a British aerospace engineer reckons he's worked out the answer to the tragic mystery of where Malaysia Airlines flight 370 crashed in 2014.
Richard Godfrey claims the plane would have hit the ocean 1993km west of Perth and says its wreckage rests 4000m below the surface.
MH370 was a commercial passenger service operated on a Boeing 777-200 that disappeared on March 8, 2014 with 239 passengers onboard.
They've been missing ever since, with a constant stream of conspiracy theories and expert search teams unable to uncover the wreckage.
Godfrey says a previous search came within 28km of where he claims the wreckage is and hopes his claims trigger a new search.
He developed his estimation of where the plane is by using a protocol known as Weak Signal Propagation Reporter (WSPR), a technology developed for digital radio which he describes as a "bunch of tripwires that work in every direction over the horizon to the other side of the globe".
Godfrey says combining the use of WSPR with satellite, weather, ocean current and plane performance data "supports an overwhelming case for a renewed search in the prime crash location of 33.177°S 95.300°E".
In an interview with Australian TV show Sunrise, Godfrey said he believed the plane was intentionally crashed into the ocean.
"It was a hijacking. It was an act of terrorism in my view," he said.
"But you know, I'm not a court of law. And I can only say that that's my current theory. I'm still open if the authorities want to reveal more information that they may have."
Sunrise host David Koch described Godfrey's prediction as an "incredible breakthrough".
There have been multiple large-scale searches for MH370 over the years by various international authorities.
At this stage it's unknown whether a new search will be undertaken based on Godfrey's theory.
