If this plane was shot down by an Iranian missile?
Why was this plane was targeted?
If so, who/whom on board was the target?
I, personally, think that IR suspected bombers at the time. There was a FReeper last night that posted that the airspace was being closed. Over an our later it hit the wires that an airplane had crashed.
The Canadians. A lot of them. Iran was also telling the world it would ground air traffic. Just guessing.
