No Sh*t, Sherlock

From Fox News: Investigators trying to solve the disappearance of a Malaysia Airlines jetliner have concluded that one of the pilots or someone else with flying experience hijacked the missing Boeing 777 and steered it off course, according to a Malaysian government official.
The official, who is involved in the investigation, told The Associated Press on Saturday that no motive has been established, and it is not yet clear where the plane was taken. The official spoke on condition of anonymity because he was not authorized to brief the media.
The official said that hijacking was no longer a theory. "It is conclusive," he said.
He said evidence that led to the conclusion were signs that the plane's communications were switched off deliberately, data about the flight path and indications the plane was steered in a way to avoid detection by radar.
Meanwhile, Malaysian Prime Minister Najib Razak said at a press conference on Saturday that investigators now know that the airliner's communications were deliberately disabled and that it turned back from its flight to Beijing and flew across Malaysia.
Najib also said that authorities are now trying to trace the airplane across two possible "corridors" -- a northern corridor from the border of Kazakstan and Turkmenistan through to northern Thailand, and a southern corridor from Indonesia to the southern Indian Ocean.  http://www.foxnews.com/world/2014/03/14/malaysia-airlines-search-heads-toward-indian-ocean/
I've been saying from Day 1 that this was a hijacking as opposed to a mechanical malfunction.
The question I have had is what happened to it after it was hijacked.  And main question is why no cell phones were able to transmit any information, along with any pilot communications?
The other strange thing about this case is that every available satellite is staring down from space in the possible crash areas.  I am sure there are drones and submarines also looking.  And there is nothing.
Or least, that is what they are saying.
I am sure there is at least 1 country, and I don't which one, knows what  happened to the airplane.
But they are not coming forward because of embarrassment or their potential involvement.
I still say the airplane crashed somewhere, but how and where, I don't know.
