Very interesting that report omits official Russian primary radar plot with Ukraine military plane very near of MH17 in the moment of accident. Not a word in article about another traffic!
I don't believe in story of SAM Buk. When launching and climbing the sound is extremely loud, everyone in radius 15 km should hear it. In war zone, everyone is aware of sounds like this. On both sides. In such high populated area, it should be hundreds or thousands of witnesses. But there is no one. I believe that no side launched any SAM, regardless if deliberately or by mistake.
