The trouble with Flying Lawyer's stance on discussion is that virtually EVERY "accident" whether that be in the air or in a car could possibly lead to a prosecution for some violation of law.
So that means following the above logic we can pretty well shut down PPRUNE and every other web forum as we would be not allowed to discuss incidents or accidents - any of them until both the AAIB report is out and the police/DPP have stated there are not going to prosecute: whether that was the pilot, the CAA, the maintenance or anyone else.
This accident in particular has been and is being discussed in virtually every forum I know - even on ISP forums plus the non UK ones outside of UK legal jurisdiction.
As regards any criticism of the pilot - well sorry, but the AAIB let the cat out of the bag good and proper as to the direction they were looking in their Special Bulletin S3/2015 of the 4th Sept 2015.
This gave the speed of the aircraft inverted at the top of the "loop", and a pretty good estimate of the altitude. They mentioned internal cameras showing the instrument panel and further stated that to date no abnormal indications have been identified and that throughout the flight the aircraft appeared to be responding to the pilot's control inputs.
