I was in Grand Forks, North Dakota, at UND, and 19 years old. Got out of the shower and roommate was telling me that a plane had hit the WTC tower and had the news on TV. Sat down and started watching with him, then right on live TV, the second plane hit. It went from "accident speculation", to "holy shit this is some kind of attack" really quick. UND is an aviation school, and most of the people there are pilots. So immediately all classes were cancelled, all flights were grounded, the flight-line was shutdown, and we had students stranded all over the US and Canada as the FAA forced everyone out of the sky. The local air force base scrambled bombers and reserve F-16 units. My other room mate was stuck in Canada for 5 days before he was cleared for flight to come back to Grand Forks. I still remember that whole day quite vividly. Spent the rest of the day just sitting in my room smoking cigarettes and watching the news with my roommate.
