April warning
slamer quotes an excerpt which in turn refers to an advisory that had been issued by ICAO back in April, about three months prior to the incident. April of 2015, ICAO went live with a repository of information about conflict zones (one of the recommendations which grew out of ICAO's conflict zones task force, established in the wake and aftermath of the MH17 shoot-down, and more particularly, out of ICAO's 2d High-Level Safety Conference in February of this year). Point is, rhetoric about assigning a major or substantial portion of blame to the Ukraine governmental authorities responsible for its national airspace assumes that their information about missile firing risks was a lot more complete than was the case (at least, based on what is known from fairly legitimate sources to date).
