I was 14.5 years from being born, but my parents were sophomores in high school when it happened. Every late November, I hear how the world stood still and people were in disbelief.

I'm with lovemyshiba on this one. The first big tragedy I remember was the Challenger explosion. I was in 2nd grade and we were actually watching the launch on tv, so I saw it happen. I can still remember the looks on the teachers faces.
