Frosh in high school when it happened. We were watching it on TV in class. Never would have guessed back then that I would have stuff flying on the remaining three.
FWIW, I've seen live a launch, STS-78 back in June 1996. Happened to be a morning launch and we were there. There are only three more Shuttle missions ever, seeing a launch is very memorable...
