You seem disappointed that the report fails to criticise the flight crew in any way. Maybe there is a reason for this? They were faced with an unrecoverable situation at 500 agl. The PF disconnecting the autopilot or not had 1/40th of
all to do with the eventual outcome. None of what happened can be attributed to crew error. The very best outcome they could have achieved from the point at which they realised they had a problem was to clear the airfield perimeter and hit the ground in an area of clearway with a high rate of descent. Which is exactly what they achieved. The AAIB report would have clearly stated any failure on their part had this been the case. The report didn't.
Maybe you should give it a rest? Just a suggestion
