A well researched book that takes technical aviation concepts and explains them clearly, neatly and succinctly. Its a great read regarding the crash but also gives excellent insight into the operation of modern airliners. The background to some of the nutty theories is humorous whilst being edifying regarding some of the opportunistic behaviours surrounding these events. The research and thought that the author has put into the book is obvious and his analysis of the evidence is top notch. With nearly 40 years of airline experience in cockpits , management and safety, I can confirm that the authors descriptions of pilots, the equipment they operate and the processes they use is spot on. I commend this book to professionals and lay persons alike.
