It would seem to me that several posters in this thread are placing themselves at risk of legal action.....
Cognitive impairment could have taken place during the pull up into the manoeuvre. The AAIB report mentions unusual throttle movements at that point. AH would normally have slammed the throttle fully open there, not moved it randomly.
A great pity that some cannot agree with the verdict or see the wider implications for aviation in general had he been found guilty.
Amnesia is a well-known side-effect of being placed in a coma, which I believe is what happened to AH.
