The ATSB would have to be acutely aware of not stating anything as a fact ( or suggestive, ie "he was on the piss at lunch time" ), all that is being said the way i read it is that his BAC was high, and quite a bit higher than they would expect given the environment ( ie the "in part" bit).
Again it would appear emotion is getting in the way of the evidence, never has anybody suggested he was anything less than a great bloke.
Is it suggested that any possible combination of Panadene, Hooch or Alcohol could have not reduced his capacity to safely operate this aircraft ?.
