Obviously all display pilots hope to be at the top of their game including the one involved in this accident. Why would you want the full force of the law to fall on any making an error of judgement or a mistake?. That would certainly have made me give up display flying, as would the involvement of the police in an AAIB investigation.
No one climbs into a high speed aircraft to display, with the intent to be grossly negligent or reckless in their performance.
We must accept humans are fallible, accidents will happen.
