If this really was intended for Putin then their should have been a smoking gun ready to be found in the follow up. That blog entry looked suspicious and Kiev came out with "evidence" before they'd even begun investigating but mostly it looks like disjointed chaos. Was Putins flight plan known and on schedule and was everything to schedule with the downed flight? 40 minutes between flights is too close for coincidence, it was someones black flag op and they've the blood of 300 innocents on their hands.
There is no actual proof about the presidential plane flying over that course
Even russian sources are denying it.
At the same time, there have been reports contradicting Intefax’s report that was the first and the only media source to publish the news, saying that Presidential plane was not flying over Ukraine at the same time.
As a source told Gazeta.ru online news portal, Putin’s plane does take off from Vnukovo-3 [the terminal that accepts business jets], but the president does not fly over the conflict-gripped neighboring country.
“Putin has only one jet – Board One, he does not fly other planes. This plane always takes off from Vnukovo-3, but the presidential plane have not been flying over Ukraine for a while,” the source at Vnukovo-3 terminal said.
President Putin was on his way from Brazil, where he attended the BRICS summit, to Moscow.
