Loved this. A less intensive read than the other McCullough books I've tackled, possibly because the scope is more limited. I've never known more about the Wright brothers' first flight than the basic facts. This book describes the brothers' upbringing and work ethic, detailing their approach toward building their flying machines. This period of innovation is set against the Great War we know is coming. It is incredible that within little more than a decade we went from the first flight to using these machines as instruments of destruction. I'm going to try to get my book club to tackle this.
