An expert has claimed that the missing Malaysian flight MH370 was "deliberately taken off course by pilot" and can be found 1933km west of Perth.
The mystery of what became of Malaysia Airlines Flight 370, that disappeared without a trace on March 8, 2014 while flying from Kuala Lumpur International Airport in Malaysia to Beijing Capital International Airport, has stumped the world.
All all 227 passengers and 12 crew aboard are presumed to be dead but no trace of them has been discovered - making it the deadliest incident involving a Boeing 777.
But now British aerospace engineer Richard Godfrey has revealed his belief that there "was an active pilot for the whole flight," which meant the plane itself cannot be at fault.
He also discovered unusual patterns in the plane's route, including strange 360 degree turns above the ocean, which he uses to support his theory.

He added that the plane, carrying 239 passengers towards Beijing, was possibly " being followed ".
The Boeing 777 took off from Kuala Lumpur on March 8, 2014 before disappearing a few hours later.
Contact with Malaysian authorities allegedly ceased 38 minutes after the plane departed.
Whilst the general consensus is that the plane crashed somewhere over the Indian Ocean, Richard's claims have led some passengers to believe that it was a mass murder-suicide by pilot Zaharie Ahmad Shah.
Speaking to 60 Minutes on Sunday, he said: "Everyone has assumed up until now there was a straight path, perhaps even on autopilot. I believe there was an active pilot for the whole flight."
Three hours after takeoff, Mr Godfrey claims that the plane entered an unusual holding pattern, which lasted for around 20 minutes.
This manoeuvre is designed to delay an aircraft already in flight whilst keeping it in within a specified airspace.
Typically, a pilot will be waiting for further clearance from Air Traffic Control before landing.
Mr Godfrey explained that the temporary delay might indicate that the pilot had stopped to make contact with Malaysian authorities, of whom maintain that they had lost contact with the plane soon after its departure.
He said: "It's strange to me, if you're trying to lose an aircraft in the most remote part of the Southern Indian Ocean, that you [would] enter a holding pattern.
"He may have been communicating with the Malaysian government, he may have been checking whether he was being followed.
"He may have just simply wanted time to make up his mind, where he would go from here."
While Mr Godfrey has expressed hope that the Malaysian authorities would share whether such contact had been made eight years ago, they have since told him that they are "very busy."
He added: "If it turns out the pilot was in anyway responsible, they might be faced with multimillion claims. So maybe they just hope this will go away."
Up until now no wreckage has been found, despite a $200-million search of a 120,000 square metre area.
However, Mr Godfrey believes that he has figured out the missing plane's location.
He tracked disturbances the plane's final path made in radio frequencies across the world, and concludes that MH370 crashed 1,933km due west of Perth, Australia.
He thinks it lies 4,000m under the ocean's surface along a line known as the seventh arc.
