Having worked at Orbital during the period this book covers, I was shocked at the inconsistency throughout this book. The author writes as an authority on Orbital, but in reality, he has had a very small slice of insight into what went on during that time. Critical events affecting the company as a whole which almost everyone at the company would know about did not show up in this book. For instance, two highly publicized failures of the Pegasus Rocket which occurred prior to the flight of Orbcomm were not even discussed. These failures definitely had some impact to the Orbcomm project. When you talk about Orbital, you talk about an end to end space company. That includes building the satellite, launching it, and providing the infrastructure to control it. The attempt was made at getting this across, but it really did not do justice to that topic. The book should be described as the incomplete history of the design of a satellite, not a history of Orbital. I do have to say that management personalites were described rather accurately. The engineers in the story are really depicted as an inexperienced bunch of kids who came right out of school with their "license to learn" (degree) and were directed to design a satellite system with nothing but their egos. Quite a bit of the book describes the long hours they worked and the stress involved in getting it done. This wasn't a superhuman abnormality in the engineering world at Orbital, as the author would lead you to believe. He could have told us about it in maybe 3 sentences, not 300+ pages. With that out of the way, the author could have brought this history of Orbcomm into recent history, instead of stopping before the constellation was launched. In summary, I have to say this book was a big disappointment. It doesn't do justice to Orbital or provide a consistent picture of the Orbcomm constellation development.
