Query: It's not rocket science, but it is about rocket science!!

While this is not the be all end all of astronaut books..it was written mostly by Life magazine, but with a great deal of attributed comments by the famous three. It is however one of the most all encompassing books about what goes into a spaceflight..I have read all the books, and this one is a happy blend of good background and enjoyable reading material about the lives and the stresses of the astronauts and their families and friends, and also delves pretty well into the technical aspects, but you do not need a degree in astrophyscis to understand..it's not rocket science, but it is about rocket science, so it's a fun and enjoyable read. Give it a shot, worth the price if you are a NASA and moonwalker fan. Fly NAVY!
