Your comments Boslandew bring us back to my original query, is this campaign aimed at reducing the verdict of gross negligence to just negligence? For which ever way you look at it the pilots are culpable to some extent, any other conclusion is wishful thinking or simple vindictiveness towards two senior officers one of whom has 'been there and done it'. He believed that in view of the evidence and in all probability this incident was due to gross negligence. Maybe the strict 'standard of proof' is missing but perhaps the standard is no longer relevant, many examples of dangerous and ill disciplined flying have escaped proper judgement due to this requirement for 'absolute proof' The member of the board I know was not air rank.
