Very interesting book! I could definitely tell that Doug Morris had written before this book because of how he writes (and is something he mentions in the beginning of the book). The plane information was informative, well-written, strung together well, and (mostly) made sense. The math portions were a bit too much for me (something about knots and finding the square root of the altitidue, etc.), but they only popped up once near the end. It is a bit of an older book, so published in 2007, so some well-known examples that I expected to see, weren't present; specifically, the Hudson ditching. He talked about how in flight simulations you'll have an engine fail on takeoff, and so I turned the page expecting to see the Hudson ditching, but it hadn't happened yet, so he just continued talking about simulations.
Not the type of book I expect most people to read, but it was fun to learn something new, and from someone who knew how to write an engaging story.
