Naturally, this has already been confirmed by one satellite (that 370 flew for 4 to 5 more hours and then landed, but it would take two more satellites receiving the aircraft's transmissions, at the same time, to triangulate where it landed at).
Obviously, by this time even the dumbest of the dumb (that would be the typical American) should realize this was a sky heist or air heist not a hijacking, most likely involving the AC (aircraft commander) and perhaps both pilots.
There was something mighty valuable aboard that bird, and since the cargo manifest included special handling instructions for a container of highly sensitive digital electronics, the rumor that a radically new chip was aboard might be true.
If such a chip prototype were being transported on a passenger flight, instead of a private jet, it begs the question whether the Freescale Semiconductor engineers were taking it to China for manufacturing purposes, or to hand off to the Chinese government.
We do know that Freescale Semiconductor is owned by the Blackstone Group and Carlyle Group (with investments by AIG) and whenever you have the Carlyle Group, murky things happen, and times one thousand when the Blackstone Group is involved, because, really, the Carlyle Group is simply a subset of the Blackstone Group, as anyone familiar with the two private equity/leveraged buyout firms will attest.
