We remember mission STS-51-L , the last flight of Space Shuttle Challenger…
Where were you? Please share your memory…
I was 7-years-old, and likely in school that day. I remember the talk about the “Teacher in Space” and all the buzz that many of the nations schools had about this wonderful program. But at such a young age for the life of me I can’t recall if we actually watched the launch in school that day or not; or if we simply received word that something was wrong.
Share your thoughts, what do you remember, and how old where you?
