I loved this. Book. Not usually a fan of non fiction but this surprised me. I was invested in the personal story. I learned so much about the space program and all that's involved. I was surprised by their schedule and how small the space was. Never thought of many of the situations the astronauts found themselves in. Space travel is more dangerous than I would have previously thought. The relationships in the story were intense and real. So much information about all the inner workings of the. Shuttle and space station. Now when I watch TV or a program I have a much better understand ding of the words and language used. Also gave a different perspe tive than most other space books. Brave to Mr. Kelly for sharing his story with us.
