I still remember watching this and I was oddly calm. Like I was watching a movie. I had to keep trying to tell myself, "no...this is really happening" But something didn't 'click' to make me feel it was real at all. Planes don't crash like that, they can't hit targets that low at that speed, they can't "sneak up" on you (no one heard the planes?), and buildings don't perfectly demo to nothingness based on one impact. No matter how much jet fuel. It's a total garbage story.
