I think the elephant in the room is not so much airworthiness as display safety. It being an entirely foreseeable event that an aircraft crash on its display line, appropriate mitigations were not in place. AH is responsible as the commander for the handling and the aircraft crashing. He was not in any way responsible for Shoreham Airshow’s planning and risk assessment that allowed him to be displaying over a major road. IMO these are the individuals and offices who should have faced far more scrutiny from the coroner.
