Watching the footage on this site reminds me of how I watched the events unfold on 9/11. I was at work at Apple in IL2 (Building 2 of the Infinite Loop campus.) People started getting calls on their desk phones and co-workers coming in started to share the news. An email came from Steve Jobs which I can't remember the exact contents of. One thing the email did have, was a link that was a live video news stream of the events unfolding.

The campus entered a type of lock-down. The gates to the parking garages were closed, the front-doors to the building were locked and security blocked the entrances to the campus with their vehicles. At the time, work was sort of my family so I didn't consider that some people probably wanted to leave right away to be with their loved ones. I assume they were able to do so with some effort.

Things obviously changed in the world that day. At Apple, the underground gates to the garages were always closed and you had to badge in. Security personnel were posted in the lobbies and badging in and "tailgating" were taken very seriously. The doors to the inner campus were now locked and you had to badge in and out. These were all really minor things, but it made you realize that things were no longer going to be the same as before.
