I see a VERY big difference. A streaking missle across a dark/dusk sky is easy to see. Very easy. All I see concerning this event is hysterical New Yorkers all telling different stories, talking about being attacked by nukes and becomming avaiation experts over night. I doubt this happened the way most "eyewitnesses" think. Its not like the Trade Center video where you can rewind and rewind, to see it again.
Accidents happened before 9/11, and they will continue. Heck, one probably happened on 11/12!
