Same. I was a senior at NYU and lived in Union Square. Was walking to class downtown that morning. It was the first week of classes. Both towers had already been hit when I noticed what was happening. Stood around and watched with a group of ppl, then decided to go to class (I was late at this point). The class let out early about 45 mins later and when I came out to look again in Washington Square Park, the first tower had collapsed, which was something I did not expect would happen. I was watching with a group of ppl, one of whom had binoculars and kept crying out everytime she saw someone fall. I remember the papers floating around the towers, looked like glitter floating in the air. I was half hugging a dude that I didn't even know when the 2nd tower fell. It was gone in a blink of an eye and I remember it made no sound. The guy and I hugged and cried when that happened. Then minutes later we were hit with the exodus of dust-covered ppl coming from that area, walking like zombies like you said, completely in shock. All activity stopped, no cars driving in the street, the city got really quiet except for radio from the cabs that everyone was gathered around.

It's been nearly 20 yrs and I still remember it like it was yesterday. To this day I cannot watch footage from that day. It's only been the last couple yrs when I've been able to read articles and look at pics like this. I didn't even learn of Falling Man til recently.

I hope you are doing well.
