Hamster,
No, you've got it wrong. Bibel's book is very much supplementary to the official aviation accident investigations. It discusses the science and technology underlying accidents. In the preface, Bibel states that the book is about aviation accidents "that illustrate concepts of physical science". He aims to reveal "intriguing accident stories to a general audience and to illustrate and teach the critically relevant science and engineering principles that guide aircraft design". I believe there's a real need for a book like this, given the typical sensationalist coverage of aviation accidents by the media. I'm sure that many professional aviators would also gain from reading this book.
