Malaysian PM says lost airliner was diverted deliberately
KUALA LUMPUR (Reuters) - A missing Malaysian airliner appears to have been deliberately steered off course after someone on board shut down its communications, Prime Minister Najib Razak said on Saturday.
A week after the disappearance of flight MH370, Najib said its last transmission of satellite data came nearly seven hours after it disappeared from radar screens.
But the new satellite data gave no precise location, and the plane's altered course could have taken it anywhere from central Asia to the southern Indian Ocean, he said.
Minutes after the Malaysian leader outlined investigators' latest findings, police began searching the house of the aircraft's 53-year-old captain for any evidence that he could have been involved in foul play.
The Malaysia Airlines Boeing 777-200ER vanished en route from Kuala Lumpur to Beijing in the early hours of March 8 with 239 passengers and crew aboard.
Najib, giving his first statement at a news conference since then, confirmed reports that investigators believe somebody cut off the plane's communications reporting system, switched off its transponder and steered it west, far from its scheduled route.
"In view of this latest development the Malaysian authorities have refocused their investigation into the crew and passengers on board," he said.
"Despite media reports the plane was hijacked, I wish to be very clear, we are still investigating all possibilities as to what caused MH370 to deviate."
Search operations by navies and aircraft from more than a dozen nations were immediately called off in the Gulf of Thailand and the South China Sea to the east of Malaysia, where the plane dropped off civilian air traffic control screens at 1:22 a.m. last Saturday (1722 GMT on Friday).
Malaysia said new data showed the last communication between the missing plane and satellites at 8:11 a.m. (0011 GMT), almost seven hours after it turned back and crossed the Malay peninsula.
The data did not show whether the plane was still flying or its location at that time, presenting searchers with a daunting array of possible last locations. Seven hours' more flying time would likely have taken it to the limit of its fuel load.
Najib said the plane's final communication with satellites placed it somewhere in one of two corridors: a northern arc stretching from northern Thailand to the border of Kazakhstan and Turkmenistan, or a southern one stretching from Indonesia to the vast southern Indian Ocean.
"Clearly, the search for MH370 has entered a new phase," said Najib, whose government has come under criticism for its slow release of information surrounding one of the most baffling mysteries in aviation history.
India stepped up its search in two areas at the request of Malaysia - one around the Andaman and Nicobar Islands and another further west across the Bay of Bengal - but found no evidence that would indicate that the plane had come down in its waters, the Defence Ministry said.
A senior military official in Port Blair, capital of the archipelago, said Indian aircraft had combed waters stretching up to 300 nautical miles (550 km) offshore and overflown all 572 islands in the chain but "we don't have anything so far".
India's Eastern Naval Command was investigating a separate rectangular 'box' 15 km wide by 600 km long, some 900 km east of Port Blair, but had found nothing.
About two-thirds of the passengers on board the flight were Chinese, and Beijing has been showing increasing impatience with the speed and coordination of the Malaysian search effort.
On Saturday, China said it had demanded that Malaysia keep providing more thorough and accurate information, and added that it was sending a technical team to Malaysia to help with the investigation.
China's Xinhua state news agency said in a commentary that Najib's disclosure of the new details was "painfully belated".
"And due to the absence - or at least lack - of timely authoritative information, massive efforts have been squandered, and numerous rumours have been spawned, repeatedly racking the nerves of the awaiting families," it said.
The fate of flight MH370 has been shrouded in mystery since it disappeared off Malaysia's east coast less than an hour into its scheduled flight from Kuala Lumpur to Beijing on March 8.
But investigators have increasingly discounted the possibility of an accident due to the deliberate way it was diverted and had its communications switched off.
Investigative sources told Reuters on Friday they believed the plane was following a commonly used navigational route when it was last spotted early on Saturday, northwest of Malaysia.
Their suspicion has hardened that it was flown off-course by the pilot or co-pilot, or someone else with detailed knowledge of how to fly and navigate a large commercial aircraft.
No details have emerged of any passengers or crew with militant links or psychological problems that could explain a motive for sabotaging the flight.
The experienced captain, Zaharie Ahmad Shah, was a flying enthusiast who spent his off days tinkering with a flight simulator of the plane that he had set up at home, current and former co-workers said. Malaysia Airlines officials did not believe he would have sabotaged the flight.
The 27-year-old co-pilot, Fariq Abdul Hamid, was religious and serious about his career, family and friends said, countering news reports suggesting he was a cockpit Romeo who was reckless on the job.
As the search enters its second week, several governments are using imagery satellites - platforms that take high definition photos - while data from private sector communications satellites is also being examined. China alone says it has deployed 10 satellites.
"The area is enormous. Finding anything rapidly is going to be very difficult," said Marc Pircher, director of the French space centre in Toulouse. "The area and scale of the task is such that 99 percent of what you are getting are false alarms."
The corridors given by Najib represent a satellite track, which appears as an arc on a map. The plane did not necessarily follow the corridor, but was at some point along its path at the moment the signal was sent.
Officials at Kazakhstan's state air navigation service were not available for comment while in Turkmenistan, state aviation officials referred queries to the Foreign Ministry.
Afghanistan's ministry of aviation said its controllers were certain the plane had not crossed their airspace. A spokesman for Pakistan's civilian airspace authority said: "We have not received any requests from Malaysia authorities for help, nor have we any information on the plane's whereabouts."
Earlier, a source familiar with official U.S. assessments of electronic signals sent to geostationary satellites operated by Britain's Inmarsat said it appeared most likely the plane had turned south over the Indian Ocean, where it would presumably have run out of fuel and crashed into the sea.
If so, just finding the plane - let alone recovering the "black box" data and cockpit voice recorders that hold the key to the mystery - would be a huge challenge.
The Indian Ocean has an average depth of more than 12,000 feet, or two miles (3.5 km). This is deeper than the Atlantic, where it took two years to locate wreckage on the seabed from an Air France plane that vanished in 2009, even though floating debris quickly gave an indication of the area of the crash.
Any debris would have been widely dispersed by Indian Ocean currents in the week since the plane disappeared.
"We have many radar systems operating in the area, but nothing was picked up," Rear Admiral Sudhir Pillai, Chief of Staff of India's Andamans and Nicobar Command, told Reuters.
"It is possible that the military radars were switched off as we operate on an as-required basis. So perhaps secondary radars were operating, which may not have the required range to detect a flight at an altitude of 35,000 feet."
The other interpretation was that the aircraft continued to fly to the northwest and headed over Indian territory.
The source said it was believed unlikely the plane had flown for any length of time over India because it has strong air defence and radar coverage that should have allowed authorities to see the plane and intercept it.
It is extremely rare for a modern passenger aircraft to disappear once it has reached cruising altitude, as MH370 had. When that does happen, the debris from a crash is usually found relatively quickly, close to its last known position.
In this case, there has been no trace of the plane, nor any sign of wreckage.
The maximum range of the Boeing 777-200ER is 7,725 nautical miles or 14,305 km. It is not clear how much fuel the aircraft was carrying, though it would have been enough to reach its scheduled destination, Beijing, a flight of five hours and 50 minutes, plus some reserve.
