I was a junior in College at ISU... I lived in an apartment with three close friends. We had spent the night before over indulging in beer during the Broncos and Giants Monday Night football game.
Slightly hungover and typically late for class, I decided to pop on the TV to see what the weather was supposed to be for the day. I saw the first tower smoking and just thought it was a fire, but then the ABC broadcast started talking about how a plane had flown into it. I just figured it was an accident until I literally watched the 2nd jet fly into the 2nd tower. I stood there in shock for a moment and then quickly awoke my roommates to tell them WWIII was starting. We thought we were going to be living some kind of Red-Dawn movie...
I spent the rest of the day glued to the TV...I remember watching the pandemonium that played out over the hours and days after the attacks...with food, water and gasoline supplies.
Watching the 2nd plane hit was immediately burnt into my memory for life. I will never forget the feelings it created.
