In my opinion, a must read for any aviation enthusiasts, particularly those interested in the operation of widebody jet aircraft. The latter third of this book documents, in great detail, the flight of a British Airways 777 from London to Boston. The unexpected bonus is the first 10 chapters ranging from the Principles of Flight through to ATC and flight crew responsibilities. These are well-written explanations in clear and concise terms that anyone can understand. I cannot recall any other books on the topic of aviation that encapsulates so much valuable information in 300 pages!
