I was in study hall in the cafeteria of my high school. In the cafeteria there are glass doors to which we can see the school office. My vice principal comes running out of the office into the cafeteria and jumps onto a table to turn on the TV.
A few minutes later we saw the second plane hit the towers live. I remember it so vividly. We were scared, we didn't know what was happening. I was friends with people in New York, and my heart went out to them. I later found out that they were just down the street and had to evacuate... walk across the bridge... sit in darkness at home.
Then the pentagon was hit, and then later the plane in the field that was brought down by the courageous passengers to prevent even more destruction.
I tear up when I think about it, and I feel like it has changed everyone who witnessed it, either through TV or live in person.
