I saw some stuff on Twitter (X) recently about how most people (allegedly) mis-remember the Challenger, that very few watched it live, etc.
I do recall not watching it live, but I do remember I was in the 4th grade, and our teacher was following it by listening on the radio. I recall her being shook up, I realize now she was probably holding back tears, and word got out that it exploded. I didn't even know they had a teacher in space program.
