The Russian telling a lot of
Think about the Su Theory..
I donīt think that this possible Heli was attacking. The MH17 was shot down by a BUK.
(But it is possible that the shot was planned? ATC Rostov changed the Route directly over the Buk(s) in Snizhe; if the Missile donīt hit, the Heli is on Stand By and MH17 gets down on RU Area. )
Edit: I get an Info via PM that Russia is able to see Targets about 1000m at UA/Russian Border. At the Crash site it is about 1500m.
