For photos and analysis that suggest the plane was shot down by another plane in what might have been a botched assassination attempt on Putin and that Google are actively censoring the wreckage photos check this out.
I'm not too sure about the assassination attempt theory, why have prerecorded phone calls confessing to shooting down a passenger jet if that was the case? Seems reasonable enough for it to have been shot down by one of the Ukrainian fighter jets though. Also, assuming this was a CIA plotted false flag it must have been intended to spur a little more than EU support for the current round of sanctions. Not long since the Googlebergers met either - I wonder how many times a major violent tragedy has happened or major new outbreak of disease has been announced within a few weeks of those meetings taking place?
