I was in grade school... home from the day for some reason (sick maybe?)
I was also home sick that day, from first grade. I had become very interested in the space program and it was the first time I would see a shuttle launch on television. Actually, I don't recall seeing another until at least my teenage years. Watched on the television in my parents bedroom, and couldn't think of what to do when it exploded. I went downstairs and told my mother, and she in turn could not think of what to say back to me. It remains one of the most vivid memories of childhood.
