THE most likely crash site of the missing Malaysian Airlines jet has yet to be searched, a UK satellite company has claimed.

A major search for Flight MH370 has been under way since it disappeared with 239 passengers and crew on board after taking off from Kuala Lumpur on March 8.

Hourly electronic connections received by telecommunications experts Inmarsat revealed the Boeing 777 airliner had to have come down in the southern Indian Ocean.

Scientists from the company told the BBC's Horizon programme they had calculated the plane's most likely flight path to a "hotspot" on the ocean floor.

But an Australian search vessel, the Ocean Shield, never reached the site because it picked up other signals some distance away, thought to be from the plane's flight recorders.

These "pings" were investigated for two months during a search of 328 sq m of sea bed north west of Perth in Australia, but the source was not found. Talks are taking place on how to fund a new search.
