Really isn’t going tell them much. We already know the what when and where of the incident.
What we don’t know is the who and why and the black box would have no information in it telling us those two things.
LOL ! They took it, so KGB can now manufacture “evidences” that it all was a false flag prepared by Ukrainian “nazis” together with evil America, neocons, NSA, EU, Monsanto nazis etc. If not openly, they will be leaking these “facts” piece by piece and they will be spread around by their agents and useful idiots. Soon that crap will be all over FR, spread by FR’s club of Putin's whores.
