Query: Scholarly Work

I cannot speak to how this book sums up aviation safety, as I have only a vague overview of the aviation industry as it relates to space systems. His references and understanding of key respected theorists like Maslow and Reason however, leaves much to be desired. While he may be able to speak and write effectively about safety in the aviation industry, his application of most theory in his book is less than stellar and should not be used as scholarly reference.
