If you are going to fire a missile at an eastbound passenger jet out of JFK Airport in an attempt to shoot it down, you aren't going to do it out off the south shore of eastern Long Island where the aircraft would normally be flying at an altitude of 16,000+ feet. Instead, you are going to position yourself closer to the airport itself (off the coast of Nassau County) where the aircraft would be flying at a much lower altitude.
I think it was a military training mishap...
Think of the international implications if found to be true.
Post 73, so I don't have to repeat stuff too much.
If it was terrorboys in a boat, they got extremely lucky.
