It's odd because Kiev will make a case that would be stronger if some of the other information is there so, what, the CIA or SBU just pump out what someone asks for without telling that someone, "you need more information than requested to best make your case"?
Bottom line to me is what kind of lazy, inept, stupid, worthless, SOB responsible for dealing with passenger traffic over Ukraine didn't tell them not to fly over that area after they lost a transport to a weapons system they knew damn well could hit something flying nearly twice as high as they say their transport was flying?
Does Kiev still fly their own civilian passenger planes in and out of this area? If it's not deliberate, it's the sort of incompetence that makes it tough to believe the Kiev government knows what it's own people are doing most of the time.
Probably fog of war type stuff, not to mention lots of heavy bureaucracy still lying about that I’m sure Kiev hasn’t had time to deal with, IF they even intend to. Just clearing out the Russian spies will likely take years.
