The grieving family of missing Malaysia Airlines Flight MH370 have criticised the timing of a new book that claims the plane may have been accidentally shot down and the search for survivors covered up.

Flight MH370: The Mystery makes the incredible claim that the airline was shot down by US-Thai joint strike fighters accidentally as part of a training drill gone horribly wrong. The book goes on to claim the search party was purposely sent in the wrong direction as part of a cover up.
