All a matter of perspective. Those "engineering failures" were in fact a case of criminal negligence which, by the way, none of the actually responsible people has gone to jail for. As for "firing missiles at civilians", this latest incident reportedly happened to a rerouted plane, in airspace that was being actively contested by enemy drones at that time. Not saying that this isn't a tragedy, or that the Russian military is not to blame, but there are also lots of blanket allegations and generalizations thrown around in this thread, that just seem out of place in a supposedly discerning and intelligent community.
