The previous time a missile brought down an airliner over Ukraine (Siberian Air), the russians were saying the Ukrainians done it and the Ukrainians were doing the denying.

As an SLF, I think at the very least airlines should refrain from flying over a known war zone or missile exercise, and counting on the restraint of the participants. Surely, there is no harm in avoiding known turbulence? To me it looks like the decision to route over combattants equipped with missiles -as proven by Siberian Air- was the first hole to line up in this swiss cheese.
