'MH370 made rapid descent'

Flight MH370 was likely out of control when it plunged into the ocean with its wing flaps not prepared for landing, a new report said yesterday, casting doubt on theories a pilot was still in charge.

Malaysia Airlines Boeing 777 disappeared en route from Kuala Lumpur to Beijing on March 8, 2014 carrying 239 passengers and crew.

The report by the Australian Transport Safety Bureau found the plane's final satellite communications were "consistent with the aircraft being in a high and increasing rate of descent" when it vanished.

Analysis of the right outboard flap -- which was found off Tanzania -- showed it was "most likely in the retracted position", suggesting the plane was not configured for landing before it smashed into the ocean.

The new finding casts doubt on theories proposed by some analysts that a pilot had been flying the plane when it landed in the sea.

"You can draw your own conclusions," the ATSB's head of MH370 search operations Peter Foley told reporters, adding that the new findings showed "we're looking for an aircraft that's actually quite close to the seventh arc."

The search zone -- defined under the "most likely" scenario that no one was at the controls as the jet ran out of fuel -- is a thin, long stretch of water within the so-called seventh arc, where the plane was calculated to have emitted a final satellite "handshake" showing its location.
