It’s one of the most enduring mysteries in recent years – where is flight MH370?

The Malaysia Airlines flight disappeared on March 8, 2014, with 239 people on board.

Despite a years-long, $200m search effort covering more than 120,000sqm, the wreckage has never been found.

However, British aerospace engineer Richard Godfrey claims he has pinpointed the exact location where the plane crashed: 1,993km west of Perth and 4,000m below the surface.

He also claims that previous searches missed the crash site by just 28km.

Aviation expert Geoffrey Thomas, described the possible breakthrough as ‘very credible’.
