I'll second guess then to ask what kind of missile he would be seeing at 13,000' only 150' below his airplane. Now.....when he says missile the first thing that comes to my mind is some sort of manpad (especially since the report makes mention of terrorism) and I'm doubting whether he would really see much of anything. second option would be some type of air-to-air missile shot. Having been involved in the planning and execution of such an event - I would find it extremely unlikely that he might have gotten in the way of such an exercise without a million people screaming bloody murder!
I hope they find something out about this and then publish a factual report. I'd be very interested to hear what really happened.
