er no, I am saying primary fault is with the airline. secondary "fault" are the combatants. If you, as a civilian, go into a known war zone and then are shot (intentionally or not) the primary blame is with you for going where you clearly should not be. That you perceived the area of the war zone you were traversing to be "safe" is immaterial. You went into a warzone, you take the risk of death.
I have heard some on the news say that the plane was rerouted because of "weather". Again, there were many other rerouting choices which would not include flying through this region but they all probably cost a few bucks more. And it is not like a tornado suddenly emerged, this was a large weather system and known prior to departure.
Sorry, this is an airline risk management fail first and foremost. Arguing that combatants (and probably poorly trained ones) should know the difference between an AN-26 and a commercial jet misses the point.
