It's clear to me that the sole purpose of this book is give a brief general introduction to 50 significant air disasters. In doing so, the author aborded only the surface of the problems, without entering into detaisl. THe book, of course, can't be compared to MacArthur Job's books, that goes deeply into the accidents with diagrams, sketches, deep aviation knowledge, etc. Mind you, guys: they are books written with different purposes.
