I was a sophomore in High School. I believe I was in a Math class, because I remember coming from that wing of the school. We all met downstairs in the library to watch it unfolding live. Parents were coming and going to pick kids up, kids were being called down to the office to receive bad news and the like.
My school was only 45minutes away from the city, so we experienced some serious tragedy. The one girls father worked on the 105th which is right where the plane hit.
I didn't really think so much about my Aunt because I thought she lived fairly far away, but apparently her and her new husband had watched the second plane hit the second tower, from a top the art gallery they own.
I'll never forget going to our State meet for Cross Country and looking out at the skyline of NYC from Garret Mountain, NJ and no longer being able to see the towers like I had the year before. We could still see the smoke up in the sky and that was a week afterwards.
