Something many in the aviation community are asking is why the hell were airlines flight planning departments routing their aircraft any where near a hot war zone, especially where an aircraft has been shot down in the 72 hrs before. It has been widely reported and shown on video that high powered SAM's were being brought into the area, as well as armed combat jets.
I imagine the relatives of the victims of the aircraft will be asking this question, leading into a lawsuit of biblical proportions.
