The entire 54 minutes of cockpit communication aboard the missing Malaysia Airlines flight has been revealed, giving a complete picture of the lead-up to the plane's crucial final message at 1.07am of "All right, good night".

Despite a frantic multinational search for possible wreckage in the southern Indian Ocean, no sign of the Boeing 777 has yet emerged. Five aircraft spent two hours each yesterday flying above a remote stretch of water about 1,500 miles south-west of Australia but failed to spot either of the large floating objects detected in satellite imagery on March 16.The communication includes flight MH370's taxi on the runway to the series of messages recorded when the plane is believed by investigators to have already been sabotaged.

Warren Truss, Australia's deputy prime minister, acknowledged that the apparent debris may never be found because of the area's deep waters and strong currents.

"Something that was floating on the sea that long ago may no longer be floating," he said. "It's also certain that any debris or other material would have moved a significant distance over that time, potentially hundreds of kilometres."

Malaysia has begun appealing to the handful of nations with deep sea detection equipment for help in what may be a long search for the aircraft's black box. The search area spans 9,000 square miles across waters that are up to 13,000 feet deep.

Malaysian minister expressed fear a possible sighting of debris may be another false lead.

Searches by more than two dozen countries have turned up little but frustration and fresh questions about Malaysia Airlines Flight MH370 which disappeared on a scheduled flight from Kuala Lumpur to Beijing on March 8.

Six aircraft and two merchant ships were scouring an area of the remote southern Indian Ocean where suspected debris was spotted by satellite six days ago.
