I will never forget that day. It was a Tuesday morning, and I was sitting in an education class when this young woman comes running in and saying "I know it's not related to education, but a plane just hit one of the Twin Towers!" We didn't think much of it other than it was an accident. I went through the union on the way to my next class and saw the second plane hit. It was in that next class that the teacher told us what had happened, and a kid raised his hand. When called on he said "Excuse me, did you say a plane from Boston to...?" (I can't remember at this point). When the professor stated that yes, it was such plane, the kid ran out of the classroom. I will never forget that and have always wondered what happened to him.
For the next few nights, we had the most brilliant sunsets, which knowing what it was, was pretty disturbing. Also, living in Maine, it was a pretty busy airspace with all the planes coming over from Europe flying through that airspace, and it being silent was really eerie.
