Malaysian Missing plane mystery: Suspected debris may have sunk says Australia

Since then, investigators have been probing sabotage, hijack, terrorism and other angles that led to the disappearance of the plane but are yet to come across any tangible clues to help resolve one of the most baffling mysteries in modern aviation.

“The last report I have is that nothing of particular significance has been identified in the search today but the work will continue,” Australia's Deputy Prime Minister Warren Truss said.

Truss said the search was difficult due to testing weather conditions and because the satellite imagery was five days old.

“So something that was floating on the sea that long ago may no longer be floating - it may have slipped to the bottom.  It's also certain that any debris or other material would have moved a significant distance over that time, potentially hundreds of kilometers,” he said.

Search teams involving 26 countries are trying to locate the airliner, which went missing an hour after taking off from Kuala Lumpur.

Two large objects - measuring 24 metres and 5 metres in length - seen floating in southern Indian Ocean were considered the “best lead” so far, triggering a huge hunt yesterday.
