I was in 5th grade and my class was in the library. The principal came in, walked up to my teacher and said, "Where's the TV? The Challenger exploded." I thought he was referring to another TV - like they named their stock or something?
Then I realized what he was really talking about and I started to tell the other kids in my class. My teacher was the best science teacher in the district, so in a sad way we were lucky because they took a TV to our classroom and we got to watch all the news reports. No one else in the school got to do that.
