None of this seems to make any sense. I think we can put to bed the possibility of terrorism. At least in terms of a large scale organised plot. There have been no claims of responsibility for this event. That tells its own story. Any opportunistic terror group who saw an opportunity to claim responsibility but were subsequently shown to be talking out of their collective asses when the aircraft was found and no foul play was evident would instantly lose any credibility whatsoever and therefore much of their fear factor in the process. Do not think terrorist groups are not aware of this.
