Well, this certainly narrows it down, doesn’t it? What an “interesting” neighborhood:
[Malaysian Prime Minister] Razak said countries located in the flight corridors that are now the focus of the search have been contacted so they can share radar data and “all relevant information” with the investigative teams, which include the Federal Aviation Administration and National Transportation Safety Board.
That northern corridor runs through Afghanistan, Pakistan, India, Bangladesh and Burma.
There is a southern corridor too, but it goes mainly to the west of Australia over the Indian Ocean.
The Prime Minister added that “the flight was still communicating with satellites until 8:11 a.m. — seven and a half hours after takeoff, and more than 90 minutes after it was due in Beijing,” at which point it would have been close to running out of fuel.
Here is all that’s known (or at least, reported to be known) of the earlier path of the plane:
This is a strong statement:
[An unnamed Malaysian] official said a deliberate takeover of the plane was no longer a theory. “It is conclusive,” he said, indicating that investigators were ruling out mechanical failure or pilot error in the disappearance…
The Malaysian official said only a skilled aviator could navigate the plane the way it was flown after its last confirmed location over the South China Sea.
The possibilities are almost endless, and some of this will be pieced together through military radar from a host of countries. I would imagine most people (and here I’d include myself) would have assumed that a rogue plane would have been detected by radar whether it had its transponder on or not, and would be considered at least potentially hostile in this post-9/11 world. And yet this one was hardly noticed, and if it was it seems to have elicited a yawn—even though a Malaysian plane was already reported to be missing! The implications are staggering.
The sad and mind-boggling truth is that we don’t know what human agent was responsible for this, where the plane was taken, if it crashed or landed safely, and if the passengers and crew are alive or dead. That’s a lot of unknowns, although I believe we are not being told everything the authorities know.
[NOTE: I've also noticed many people in the comments sections of various articles keep asking why none of the passengers managed to call on their cellphones. But at very high altitudes and far from any cellphone towers, no calls could be made successfully. Some of the 9/11 passengers managed to do it because those planes were flying relatively low at times, and what is especially important is that they were always over land that tended to be generously equipped with cellphone towers (here's a very lengthy discussion; even at fairly high altitude cellphones can sometimes work if over towers). In addition, many of the 9/11 calls were on special airphones, installed in planes and designed to be used while flying.]
