Was at work when the 1st plane hit. We all thought is was some kind of accident, and were trying to get on CNN online which overload the company firewall. Ended up calling my Parents to find out what happened. I was talking to my Dad when I heard my Mom say "Be Quiet". That is when the 2nd plane hit.
Back then I worked next to the airport, and the thing I will never forget is how quiet it was outside when they grounded all of the commerical flights. That was the eeriest quiet that I have ever heard.
