I was a sophomore in high school when Challenger happened. I heard it in one class and discussed reactions in the next. I mostly remember the launch afterwards and clutching the sides of the chair for dear life watching it. I didn't breathe a sigh of relief for awhile after that. More so with every landing after Columbia.

Come to think of it, there are quite a few "Where was I?" type moments in my lifetime from the Berlin Wall to Princess Di to 9/11. And whole generations learning this stuff now as history rather than experiencing it... now I know how my parents feel!
