U.S. intelligence officials are leaning toward the theory that "those in the cockpit" -- the captain and co-pilot -- were responsible for the mysterious disappearance, a U.S. official with direct knowledge of the latest thinking told CNN.
The official emphasized no final conclusions have been drawn and all the internal intelligence discussions are based on preliminary assessments of what is known to date.
Other scenarios could still emerge. The notion of a hijacking has not been ruled out, the official said Saturday.
Malaysian Prime Minister Najib Razak told reporters on Saturday that the plane veered off course due to apparent deliberate action taken by somebody on board.

'Someone acting deliberately'
The first clue that the captain or co-pilot may have been involved stems from when the plane made a sharp, deliberate turn just after it last communicated with Kuala Lumpur air traffic controllers, and before it would have to communicate with Vietnamese controllers, according to the U.S. official with knowledge of the latest intelligence thinking.
"This is the perfect place to start to disappear," the official said.
Adding to the intrigue, ABC News reported that the dramatic left turn was preprogrammed into the plane's navigation computer. It's a task that would have required extensive piloting experience.
Two senior law enforcement officials also told ABC that new information revealed the plane performed "tactical evasion maneuvers" after it disappeared from radar. CNN was unable to confirm these reports.
Military radar showed the jetliner flew in a westerly direction back over the Malaysian Peninsula, Najib said. It is then believed to have either turned northwest toward the Bay of Bengal or southwest elsewhere in the Indian Ocean, he said.
"Evidence is consistent with someone acting deliberately from inside the plane," the Prime Minister said, officially confirming the plane's disappearance was not caused by an accident. "Despite media reports that the plane was hijacked, we are investigating all major possibilities on what caused MH370 to deviate."
Interesting, this was done on purpose and it was pre-planned.

Captian Shah was an ‘obsessive’ supporter of Ibrahim. And hours before the doomed flight left Kuala Lumpur it is understood 53-year-old Shah attended a controversial trial in which Ibrahim was jailed for five years.
Campaigners say the politician, the key challenger to Malaysia’s ruling party, was the victim of a long-running smear campaign and had faced trumped-up charges.
Police sources have confirmed that Shah was a vocal political activist – and fear that the court decision left him profoundly upset. It was against this background that, seven hours later, he took control of a Boeing 777-200 bound for Beijing and carrying 238 passengers and crew.
Yesterday, Malaysian police searched his house in the upmarket Kuala Lumpur suburb of Shah Alam, where he had installed a home-made flight simulator. But this newspaper can reveal that investigators had already spent much of last week examining two laptops removed from Shah’s home. One is believed to contain data from the simulator
Confirming rising fears, Malaysia’s prime minister Najib Razak announced yesterday that MH370 was deliberately steered off course after its communication system was switched off. He said it headed west over the Malaysian seaboard and could have flown for another seven hours on its fuel reserves.
It is not yet clear where the plane was taken, however Mr Razak said the most recent satellite data suggests the plane could have been making for one of two possible flight corridors. The search, involving 43 ships and 58 aircraft from 15 countries, switched from the South China Sea to the Bay of Bengal in the Indian Ocean.
In another dramatic twist early Sunday Indian officials however, said the search was on hold until 'fresh search areas' were defined by Malaysia. It is unclear what the reason was for the delay.
Data showing the number of plausible runways where the plane could have touched down - which need to be at least 5,000ft - offer a baffling number of potential locations.

The motivation for this seems to be political.
My theory is that flight 370 was hijacked in order to secure the release of Anwar Ibrahim, and that the mission was somehow unsuccessful.
