Missing Malaysia plane 'may have turned back' radar displays indicate the aircraft could have turned around before disappearing.

The Authorities in Malaysia has announced that they are now investigating the possibility the missing Malaysian Airlines plane had turned back before disappearing, and were widening the search area accordingly.

According to "Aljazeera report", the Malaysian aviation authorities said it was "fearing the worst" and that radar displays indicated the plane could have turned around.

This raises a lot of unanswered questions," he said. "If the pilots had the wherewithal to turn around why did they not communicate with any of the towers. Still the officials saying there wasn't a distress call."

No weather problems had been reported in the area before the plane dropped out of contact, and the pilots did not send a distress signal - something that has been highlighted by experts as unusual for a modern jetliner.

There was still no confirmed sighting of wreckage from the Boeing 777 in the seas between Malaysia and Vietnam where it vanished from screens early Saturday morning en route to Beijing from Kuala Lumpur.

The identities of four passengers on board the missing jetliner are being investigated over 'airline security fears' as planes and ships from across Asia resumed the hunt for the plane that disappeared with 239 people on board.
Investigators are also checking CCTV footage of two passengers who are believed to have boarded the plane using stolen passports.
