I spoke several times with John after reading his book; he was at Hamble after me and enlightened me on how the mentality towards safety had changed after the Trident went in at Staines coincidently after I had criticised said hiding mistakes during my course as a veiled observation at what happened in BEA.
I admired him in that he stood up against management when many, including me, would have folded. Saw a similar thing in my last carrier.
