This was the first Astronaut biography I read, and it really does a good job of capturing the hot shot test pilot mentality along with Cooper's early life. The real problem here is the UFO/paranormal stuff which comes out of nowhere at the end of the book (and it definitely goes beyond just seeing weird things in space, like people having psychic contact with UFOs). Not sure why they decided to go in that direction when writing this, especially since it's not referenced in the books description at all, but on the plus side of that he does speak about that stuff very rationally...if you consider that a plus side. But at least he never seems to buy into the things he talks about wholeheartedly...kinda?
Depending on how skeptical you are at heart, the end of the book could ruin it for you, but besides that, the rest was an even better portrait of Astronaut man-boys than Riding Rockets was. In the end, the UFO stuff makes it really hard to recommend this book to people, especially anyone with an interest in manned spaceflight or NASA history. If you can ignore the weird bits, its great, if not then you might want to just watch The Right Stuff instead.
