An event that changed the world. I still get chills thinking about that day. The best documentary, IMO, is the one from inside the towers:

I was only 11 when this happened. I still remember the day vividly. I hadn't set my alarm and woke up a bit too late to have my shower. Wondered why my mom hadn't come to wake me up. When I got downstairs she was just sitting up staring at the TV, the 2nd plane had just struck the tower ~5 minutes prior and she was sitting there like a zombie watching. I just plopped down beside her to watch too. Didn't go to school that day.
We went to Disney Land in November 2001. I remember fully armed national guard members were doing airport security in LAX. There wasn't a single lineup in all of Disney land. But most of all I remember how somber everyone was. It seemed like the whole world was trapped and twisted that morning.
