Video producer Ian Wilson and his brother Jack have arrived in the capital Phnom Penh and believe they can provide a breakthrough in the search for the missing airliner.
A self-styled MH370 hunter has arrived in Cambodia with his brother to travel to where he claims he spotted the plane on Google Maps.
British video producer Ian Wilson and brother Jack touched down in the capital Phnom Penh on Tuesday.
They believe their mission could provide a breakthrough to find the airliner which disappeared in March 2014 with 227 passengers and 12 crew members.
The flight had been en route from Kuala Lumpar to Beijing.
The official search for the main wreckage of the plane, with some scraps found, has recently been called off.
Ian and Jack, staying at a guest house in Kampong Speu, are heading to an area Ian claims to have spotted the Boeing 777-200 from MH370 on Google Maps, reports the Daily Star.
In the early hours of today UK time they will arrive at Chrok La Eang Waterfalls, a tourist hotspot.
The plane turned off course and disappeared from the radar never to be seen again and investigators presume it crashed in the Indian Ocean.
But some theorists claim Captain Ahmad deliberately crashed the plane – a theory that has never been substatinated.
Investigators have suggested the possibility of hijacking but there is no psychological or criminal evidence to suggest any of the crew deliberately crashed the plane.
Three pieces of wreckage believed to be from MH370 have been found from as far north as Tanzania and as far south as South Africa.
Investigators have considered more than 60 theories about what could have happened to the plane and have worked extensively since the plane vanished.
However, despite releasing a 1,500-page report, they admitted they still cannot say what happened.
