I was at work 30 miles from Shankstown, PA, the crash site of the 4th plane. There were a lot of fly overs of military jets, but little other information for a long time. Our Internet was down that morning, and we were getting news second hand. We knew something happened, but at first we didn't know exactly what. Was some time before we could gather all the details.
I still remember where I was when John Kennedy was shot, but not when Ronald Reagan was shot.
