I was in college but not taking classes at the time as it was a trimester school with non class periods meant for relevant work experience. I was also a US Marine reservist at the time. It took until 2006 for us to be deployed as a result of the GWT, and to Iraq not Astan. My friends and I didn't think it was anything other than an accident so we actually watched a movie. After the movie ended and it was still on the news (and they had more info) was when we knew. A relative was also a federal gov employee at the time in D.C. and amidst the initial chaos she told me there were reports of car bombs going off also. Of course we now know that wasn't the case, but it shows how chaotic and confusing things were.
