I also watched it at school. After the first one hit, we stopped and turned on CNN. It was amazing, some dumbass flew his plane into the World Trade Center, we we're all stunned.
A few minutes later another plane came into sight, and people started to scream, it then bashed into the second tower. But after a while of them burning, the smoke turned black (meaning no fire) and then the Reinforced concreted steel towers imploded outwards, on themselves.
Me and my friend we're shocked by it, he's a pyromaniac, and loves explosives, he had told me that the planes couldn't have exploded like that , so much afterwards, but at the time I didn't believe any of the shit coming out of his mouth, but I felt very patriotic and sad for our countries loss. But all of this evidence is just amazing not to second-guess Bush's administration, and Bush himself.
EDIT: Here look at this
