Russian military weapons used to shoot down planes?

In a week, there have been four planes downed near the Russia-Ukraine border:

• Three Ukrainian military planes were shot down in the last several days, the most recent, coming yesterday.  In yesterday's incident, a fighter jet was reportedly shot down by a missile coming from across the border in Russia.
• And just now, a Malaysian airline flight, traveling from Amsterdam to Kuala Lumpur, has crashed in eastern Ukraine, near the Russian border.  

The early evidence pointing to Malaysian MH17 being shot down:

• Its reported rapid descent from 10,000 meters.
• Separatists reportedly have Russian surface to air missiles, and such Russian military hardware in the hands of separatists was the reason and target for the Obama Administration's latest round of economic sanctions.
• Reuters, on the secene, has reporting that the debris of bodies extends 7 miles, suggesting that the plane had broken up mid-air.
• Debris on the ground, separate from the area on fire, intact without scorch marks; rather, large sections of the plane had been ripped apart;
• Ukraine has released an official report stating that a leader of the rebels had posted on his page, claiming for shooting down what he thought was a Ukrainian military plane, an AN-26, just prior to the reports of Malaysian MH17 going down.  This is the note (via another blog) in reference, from Igor Girkin's VK page:

17.07.2014 17:37 (MSK) Message from the militia. Sasquatch In the area just knocked the AN-26, lying somewhere in the mine "Progress". Between Kostiantynivka and Donetsk were 3 checkpoint ukrov (away from Konstantinovka on rivet -bull). Now they are removed and leave aside Kramatorsk. Fold, the beds in the car loaded, trucks are for people who are already deployed tanks, guns got (they were entrenched themselves), and all other equipment goes somewhere. Why would it? 13:50 (GMT) From Uspenka through Amvrosievka Ilovaysk proceeded towards 5 and BMP 2 Urals with podtseplennoy gun toward Novoivanovka. Periodically go shelling rare Lugansk. 16:45 (GMT) Re-opened artillery fire dill in Lugansk, strikes are in Upper Kambrody, Alexandrovka Ekaterinovka, Greenhouse.

This last item is central, aside from any forensic evidence they can find.  The Google translation might be a little rough.  Essentially, the post is referencing the Progress Coal Mine, in Torez.  I think this is the direct evidence Ukraine has spoken of.  The location in reference, is just a few miles away from where the plane crashed, in Grabovo.  For reference, see Google Maps.

Can Russia walk away with clean hands?  I don't think so, not this time.  They gave rebels weapons and training, and a rebel group shot down the plane by mistake.  Russia has lost Ukraine for forever.

Update:

And it looks like Igor Girkin has realized his mistake and has removed the portion of the post mentioning his attack: "Sasquatch In the area just knocked the AN-26, lying somewhere in the mine "Progress"." The rest of the post remains, but it is too late; Girkin can't hide the truth.

Update 2: This video showing the start of the plane explosion is curious.  It is located in an area surrounded by coal, and is pointed at the precise spot where the plane crashed.  That can't be a coincidence, can it?
