And there are more.

I had already planned a vacation day for the Friday after 9/11, because a) I had a doctor's appointment and b) it was my birthday. When our office closed for the week after the aborted attempt to resume normalcy on Wednesday, I kept my appointment. In the waiting room was a woman who'd been working in one of the towers on 9/11. She walked stiffly, and explained to the receptionist that her back was covered with cuts from a window (or glass door?) that had shattered behind her as she was escaping.
