I have read this thread with interest and conclude that the AAIB will only get busier with attitudes such as that demonstrated by Chopjock.
An "attitude" doesn't hurt any one. The "piston jockey" mentioned in the first post apparently had a similar attitude and did he crash in IMC? I think not, because he flew skillfully within his limitations and experience. Did he wish he was somewhere else? probably yes. Did he complete his journey safely? probably yes. Was he legal? probably yes. Will there be an AAIB investigation? Probably not.
