I had little background knowledge of the Challenger disaster and I‘m on a roll with space in books and tv so I thought I‘d dive into the background of the space shuttle. What a thorough read on the technical aspects of the vehicle, the political dynamics, and the big players of NASA this was! But Higginbotham dedicates most of the book to the profiles of the astronauts who were aboard the shuttle. I can see why this has many positive reviews.
