Military data suggests 'skilled' flyer turned Malaysia jet

Speaking to AFP on condition of anonymity, the official cited Malaysian military radar data that investigators believe indicate the Boeing 777 may have radically changed course and headed northwest towards the Indian Ocean.
"It has to be a skilled, competent and a current pilot," the official said.
"He knew how to avoid the civilian radar. He appears to have studied how to avoid it."
The intended flight path for the Kuala Lumpur-Beijing flight was to be north over the South China Sea and Vietnam.
The new information, coupled with multiple corroborative but unconfirmed reports, suggests the investigation into the disappearance of Malaysia Airlines flight MH370 was increasingly focusing on something going wrong in the cockpit.
Analysts have said that could include a sudden loss of cabin pressure or other mechanical event that incapacitated the pilots, catastrophic pilot error, or more sinister possibilities such as the plane being commandeered by a hijacker or rogue member of the flight crew, or pilot suicide.
All signs so far point to a "controlled, deliberate act, not a mechanical failure", said Scott Hamilton, managing director of US-based aviation consultancy Leeham Co.
The mounting reports of an unexplained banking to the west have coincided with a shift of search and rescue resources toward the Indian Ocean.
- Search extends to Bay of Bengal -
A US destroyer and surveillance plane joined expanded search operations Saturday in the Bay of Bengal. The international search effort had focused in its early days on the South China Sea.
Pentagon spokesman Colonel Steven Warren said the USS Kidd guided missile destroyer and a P-8 Poseidon aircraft had been deployed to the "western search area" at the request of Malaysian authorities.
While the Kidd would search the Andaman Sea and Bay of Bengal, the P-8 would cover "a much larger search area... the southern portion of the Bay of Bengal and the northern portion of the Indian Ocean," Warren said.
The Boeing 777, with 239 passengers and crew on board, vanished March 8 over waters between Malaysia and southern Vietnam. The night was clear and no distress signal was received.
The hunt had initially focused on the South China Sea but has shifted dramatically given the absence of any findings, and following the indications the plane altered course.
India's navy said it was doubling, at Malaysia's behest, the number of ships and planes it had deployed to search the Indian Ocean waters around its remote Andaman and Nicobar islands.
The six vessels and five planes were concentrating on an area "designated" by the Malaysian navy in the southern region of the Andaman Sea, naval spokesman D.K. Sharma told AFP.
Close to 60 ships and 50 aircraft from 13 countries have been deployed across the entire search zone since MH370 went missing.
- Reports of altered flight path -
For distraught relatives of the passengers and crew, the expanded search offered no immediate relief from the anguished frustration of a week tainted by false leads and rumours.
Malaysian Transport and Defence Minister Hishammuddin Hussein on Friday repeatedly refused to comment on what he termed "unverified" information, as reports of an altered flight path mounted.
Multiple US media reports also had cited unidentified officials as saying a satellite continued to detect the plane's automated communication system for hours after radar contact was lost.
The New York Times reported that Malaysian military radar data had shown the airliner altering course at least twice and changing altitude -- sometimes erratically.
"If this is criminal -- as looks increasingly likely -- then information is going to be held closely to prevent leaks," Hamilton said.
Hishammuddin confirmed the expansion of search operations in the Indian Ocean and said Malaysia was "sharing information we don't normally share for security reasons", hinting at confidential military data being scrutinised for clues.
The widening of the geographical search parameters poses enormous logistical challenges for wreckage identification and recovery.
The vast Indian Ocean has an average depth of nearly 3,900 metres (12,800 feet) and any debris would have been widely dispersed by currents after a week.
"Wind and sea conditions are definitely going to play a very big part if there is wreckage, and if it happens to be in the Indian Ocean. It is an immense area," said Greg Waldron, Asia managing editor for aviation industry magazine FlightGlobal.
If it does turn out that Malaysian military radar tracked the missing aircraft, there will be questions as to why the air force was not sent to investigate a large plane flying with no transponders over a strategically sensitive region.
The plane has one of the best safety records of any jet, and the airline also has a solid record.
