Gero has done the aviation safety community a great service by putting out this book. Students of the subject would be well advised to read it cover to cover. The most noteworthy content is the peek behind the veil at former Soviet accidents (which may have been the impetus for the writing of the book in the first place).Where Gero falls short is in his failure to mention a number of well-documented, high-profile accidents with significant implications to public safety. For example, the June 1995 crash of a B-52 at Fairchild Air Force Base, Washington made international news, but is not discussed in this book. A 2002 update of both this book and his equally readable "Air Disasters", perhaps combined in a single volume, would be welcome to both add to the current content and bring attention to the final rulings on a number of high-profile accidents that occurred in the late 1990s.
