Missing Malaysian Plane #MH370 Latest: Web detectives claim to have spotted missing plane; ...student posts satellite image showing a jet over the jungle

Web sleuths from across the world have joined in the search for the missing Malaysia Airlines flight MH370 by turning to the map search website Tomnod.

The online community has added to the confusion surrounding the 12 day mystery of the missing jetliner as people post possible sightings and new theories.

Investigators meanwhile probing the disappearance of the plane believe it most likely flew into the southern Indian Ocean, a source close to the investigation said today.

Elsewhere, users of social networking site Reddit have posted an image which they claim appears to show debris from the plane in the Strait of Malacca.

The area highlighted the same place where crew on a Greek-flagged oil tanker on Sunday responded to radio reports of suitcases found floating on the surface.

Users of Reddit have also suggested the scale of the potential debris matches that of the missing aircraft.

Another image to have gained attention appears to show a plane flying over a jungle, discovered by a university student in Taiwan, according to Taiwan's China Times.

The authenticity of the photo by the Taiwanese student, also posted to Reddit on Sunday, has not yet been verified and online commentators have raised questions over the veracity of the image, with some pointing out it appears to be a different model to the missing Boeing 777. The plane also appears to have been painted white.

The image surfaced at the same time as news emerged that Malaysian villagers claim to have seen the missing jet flying over the north east of the country at around the time the aircraft is thought to have made a 'U-turn'.

At least nine people - tuna fishermen, farmers and villagers - in Kelantan in Malaysia have made reports to police about seeing lights in the sky and some said they heard the loud noise of an engine.

Similarly, residents of a tiny island in the Dhaalu Atoll in the Maldives say they saw a plane with Malaysia Airlines markings in the early hours of Saturday March 8.

Investigators probing the disappearance of the plane believe it most likely flew into the southern Indian Ocean, a source close to the investigation said today.

An unprecedented search for the Boeing 777-200ER is under way involving 26 nations in two vast search 'corridors', one arcing north overland from Laos towards the Caspian Sea, the other curving south across the Indian Ocean from west of Indonesia to west of Australia.

'The working assumption is that it went south, and furthermore that it went to the southern end of that corridor,' said the source, who spoke on condition of anonymity.

The view is based on the lack of any evidence from countries along the northern corridor that the plane crossed their airspace, and the failure to find any trace of wreckage in searches in the upper part of the southern corridor.
