Malaysian Airlines flight shot down in Ukraine

To be fair, the equipment needed to shoot down something from 10 kms height is not something anyone would expect rebels to have. And this plane wasn't the only one flying through the area, a lot of the companies are changing their flight routes now after this.
But gee, i sure wonder where they got something like a buk missile system, it's not like russia made those or anything
This whole thing just reeks, AFAIK some of the rebels even bragged about shooting down what they had thought to be a ukranian cargo plane.
My thoughts go out to the ones who lost loved ones.

Wouldn't surprise me if it was the United States based on our lovely history with funding insurgents against undesirable political regimes i.e. Peshawar Seven during the Soviet Union's involvement in Afghanistan.
