I was in grade 10 if I recall. First year in the new school. I remember someone mentioning something about a plane hitting a building called the world trade center in New York. The details were very vague, I'm not even sure where he heard it from given we had been in school since the morning. I pictured a small twin engine plane and the pilot lost control somehow, or perhaps some kind of malicious thing, but I pictured no more than a few people dead and a couple broken office windows and cubicles. Nothing more dratic than that.
Throughout the day more people talked about it but nobody really knew what really happened, it was all speculation. The Pentagon was also mentioned. Teachers would not let us talk about it because it was disturbing class. Finally, end of day arrives, I got home and put it on the news and realize exactly what had just happened, and just how big these buildings were, and the fact that they actually collapsed. My parents got home and had heard more about it at work since they had TVs up and everything and we watched the news together most of the night. Also got notice that we had an emergency service at our church to pray for those that were affected and family of those affected.
There was also the plane in Pennsylvania, I think at this point they were still trying to find it, or maybe not, I can't recall.
It was pretty surreal watching it over and over every time they showed the planes go through. I'd say that for at least a month after I was still glued to the news just to follow everything such as the start of the Afghanistan war.
