I think every generation has a "Where were you when..." moment in time.
Of course these days, it's 9/11.
But also for people my age, the Challenger Explosion brings back very vivid memories.
For me, I remember mostly confusion-about how it happened and who could it happen to next. I also remember feeling extremely sad for the families of the people who died.
I was sitting in the gym on a chair because my knee hurt. Everyone else was on the floor. When we watched the playback on the TV, I remember getting out of the chair and joining my classmates-I wanted to be as close as I could be to the people I knew.
That was 20 years ago. It's amazing how time just slips away. Amazing and scary, really...
