The Malaysia Airlines MH370 plane has been missing for four years after vanishing over the Indian Ocean.
Despite two large-scale searches of the sea bed off the coast of western Australia, only scattered pieces of debris have been found.
But a new search is under way after a Google Maps snap that some believe proves a plane had crashed in a high-altitude jungle in Cambodia.
The new development comes as Daily Star Online revealed the final messages sent to the missing plane – which until now have been kept secret.
Last week the first helicopter search of the area northwest of Phnom Penh was completed by aviation experts desperate to get their hands on the £53million finder’s fee.
Zorba Parer, an aviation consultant, Nara Kang, a local entrepreneur, and journalist Michael Carr rented a helicopter for a trip into the jungle but came back empty handed.
Mr Parer – who used to work for NASA – has rubbished claims the jungle is uninhabited, and claimed anyone who may have witnessed the plane crash would have sold the parts for money.
Writing on his blog, he said: “Contrary to what Google Earth says, this mountain is not an uninhabited area. We saw houses in the valleys.
“The majority of people living here are poor farmers, and if there really was a crash, all the pieces of iron will have been collected or sold.
“If there was a real crash, all the pieces would have been sold”
“We can conclude any such action would have happened instantly, such as the collection of bodies or pieces of metal to sell.”
The group also said any search of the jungle on foot would take up to 10 days and would be very dangerous due to poisonous animals and illegal poachers.
Last week the Chinese government used observation company Space View to focus in on the high-altitude area in an attempt to find the plane.
However, the firm said there was no sign of any aircraft.
But the company also said there was a high cloud cover, which could have prevented them seeing the whole site.
Tech expert Ian Wilson is now hoping to be airlifted to an area three miles from where he claims he has pinpointed the Malaysian Airlines flight using Google Maps.
MH370 took off from Kuala Lumpur and was heading to Beijing with 239 people on board.
But at 12.14am on March 8, 2014, the plane lost contact close to Phuket island in the Strait of Malacca.
Before that, Malaysian authorities believe the last words heard from the plane, from either the pilot or co-pilot, were “Good night Malaysian three seven zero”.

Satellite “pings” from the aircraft suggest it continued flying for around seven hours when the fuel would have run out.
Experts have calculated the most likely crash site is around 1,000 miles west of Perth, Australia.
Only three confirmed fragments of MH370 have been found, all of them on western Indian Ocean shores, including a two-metre wing part known as a flaperon.
Several theories have emerged about how the plane disappeared, with some suggesting it was deliberately crashed into the sea by the pilot.
