Fireflybob, I think maybe your comment was removed, however -
re: hindsight - this has not come out of the blue. Far from it. Aircraft after aircraft has been shot down in Ukrainian airspace - the airlines decided it was business as usual despite those undisputed facts.
It's not a question of hindsight - there needs to be an inquiry into how commercial airliners have been allowed to continue to operate in an active war zone.
