You should read Lovell’s “Lost Moon.” It’s mainly about 13 but he tells great stories about 8, about his test pilot days. I bought one off ebay for just a few dollars. Another good one is Gene Krantz’s “Failure is not an option.” It has great stories about the Mercury, Gemini, and Apollo missions. I never knew this until reading it that he never actually said, “Failure is not an Option.” I got Apollo 13 and a telescope for Christmas when it came out when I was 13ish in 95 and I’ve been obsessed with anything space related since.
