My heart, and my prayers go out to everybody who was even remotely effected by the tragedies that took place on September 11, 2001.
The news sent shock waves through Chicago, causing mass confusion, terror, and concern, especially for the Sears Tower, and John Hancock Buildings.
I work in a very well known building in Chicago's loop (major downtown-area), and believe me, people were in a serious panic. The majority of our senior managers were out of town at a conference, so the other "managers" were acting like they couldn't make a decision without guidance. People were practically in tears with fear that there was an airplane on the way to our building. They wanted out!
Our managers finally decided to release us, because there was no work being done. People were running, I mean, literally running, out of the building. A couple of hours later, our entire building was evacuated. It was an unreal experience.
