Russia isn't the only one being accused of a cover up. -Zero Hedge

Ukraine's SBU security service has confiscated flight traffic controllers recordings of the Flight 17 disaster. -Zero Hedge.  Zero Hedge feels that with the black box in Russian hands and these recordings in Ukrainian hands it is now no longer possible for outside parties to determine what happened

My Comment: 
Zero Hedge isn't a 100% reliable source but i agree here. There is a very good chance that these recordings will be edited if and when they are released to other investigators. The same thing is true for the Russians, who have been accused of a cover up as well.  Supposedly the United States Government has the capability of determine who fired what with signals and other forms of intelligence. Of course the United States government would never lie about what happened for their own gain! (sarcasm). Sigh, this is going to be such a politically charged investigation that conspiracy theorist will have a field day, even though it's fairly obvious what happened. Some trigger happy Russian made a huge mistake. Russia will downplay and deny, Ukraine and the United States will exaggerate and the truth will be ignored.
