Does David Hill credit the service inquiry (SI) report of the same accident anywhere in his book (available to read on the Gov.uk website)? I ask this because the introduction in his book is, more or less, a word-for-word copy of paras 1.3.1-1.3.4 of the SI report (Narrative of Events]. And without Hill’s acknowledgement of that source, he is committing plagiarism and possibly in breach of copyright law.
