It's been one week since a Malaysia airliner jet mysteriously vanished but still the authorities are baffled.
The Malaysian Prime Minister said the communications systems of the missing aircraft had been deliberately disabled, after that the plane changed course and could have continued flying for a further seven hours.
(SOUNDBITE) (English) MALAYSIAN PRIME MINISTER NAJIB RAZAK SAYING:
"Up until the point at which it left military primary radar coverage, this movement is consistent with deliberate action by someone on the plane. Today, based on raw satellite data, that was obtained by the satellite data service provider, we can confirm that the aircraft shown in the primary radar data was flight MH370."
The authorities are now trying to trace the plane across two possible corridors from the border of Kazakhstan through to northern Thailand and also south to the southern Indian Ocean.
There's been a massive international air and sea search for the aircraft
