Meanwhile, more details of the investigation have been revealed. The pilots, crew members and ground staff are now at the center of a Malaysian police investigation. And there's mounting evidence to suggest the plane's disappearance was meticulously planned.

Malaysian police are now digging into the financial status of the pilot and co-pilot in the cockpit.

An ever greater expanse of land and water.

Malaysia says the search for the missing jetliner has been re-calibrated to the northern and southern corridors of a vast swathe of Asia, where the missing jetliner is believed to have finally disappeared.

And an ever-expanding timeline of events before flight MH370 vanished.

"Initial investigation indicates to us that it was the co-pilot who basically spoke the last time it was recorded on tape," said Ahmad Jauhari Yahya, Malaysia Airlines CEO.

And that message was "All right, good night". No mention if the plane's ACARS system was deliberately switched off. The timing of the last words has sharpened suspicions of sabotage.
