First, this book is not a "novel" but a "dossier" collecting all that we could say about this plane crash. Certainly any accident is sad and often the causes and circumstances are poorly resolved. Many praise the quality of the "writing" ... the work is felt but some "mistakes" in vocabulary (the term "merchandising" for example) or "syntax" ("have agreed") are spots. The story drags in length and the author uses any information referring to a character or object to reach the reasonable number of publishable pages.
On the bottom we have to do "a little different because metaphysics" with some trite reflections on the "chance", "fate", the "contingency" ... Anyway ... this is a book that does not fly further ...
