How British satellite company Inmarsat tracked down MH370
Call me a conspiracy nut, but here's what I believe may have happened:<p>It's almost a certainty that the US government has spy satellites video recording the entire planet at all times, at a level good enough to distinguish individual aircraft.  The US spy agencies probably knew where the plane was right away, but they can't just tell everybody or the jig is up.<p>So they may have just contacted this satellite company, told them where the plane is, and came up with a technical explanation of how it was located.
