I think the patent is a red herring. I'm sorry I fell for it. The existence of Freescale technicians on the flight may be connected with a motive for hijacking/murder, or it may be a coincidence. My tin hat's on standby for that one, mainly due to the speed with which they were all dismissed as 'admin' which wasn't true. You just have look at some of their qualifications.
Not being an expert in radio signal doppler analysis, I have no idea whether the southern route is as certain as we've been told. Going North instead, there are a few credible - not likely, but credible - scenarios that would end up covering about a quarter of the planet as potential destinations: some of them very remote, on land as well as sea.
YY to the vastness of oceans.
I want to know whether US surveillance have photos! If not, why not?! They're very proud of their planetary observation; I think they've played this wrong unless they did nick the plane.
