I was at work sitting at my desk when the insurance agent who worked upstairs ran down to tell us that a plane had crashed into one of the world trade buidings. At first I didn't understand exactly what was happening and just didn't take it seriously. Plane crashes happen all the time. That is, until he ran back downstairs and said another one went into the other tower.
I bolted upstairs to watch his little black and white tv he had in his lunchroom. He pulled it out and put it on in his main office and we just stood there horrified as it was played over again.
I don't remember how I got thru the rest of the day. It felt like the beginning of the end of the world for a while. Hard to work after that. When we heard about the third plane that was headed for the White House we were all wondering what was going on.
