Pittsextra - maybe they have looked at the sortie , spoken to the pilot and everything was OK, entry height, speed etc but something went wrong with the aircraft which the pilot couldn't correct and therefore not pilot error. I don't think ,from the footage I have seen, he was displaying over the road, just this is where he came out of the loop, either intentionally or by fault.
The AAIB are primarily investigating the accident and trying to establish the cause, so that they can identify improvements/recommendations to prevent such a tragedy happening again. Like Farnborough all those years ago, when crowdlines were introduced etc. The results of this will also assist the CAA revise the existing documentation on airshow hosting, display pilots, licences etc that they are reviewing as a result.
'interested parties could have been actively engaged in the detail of this sortie and how it came about. All of that detail was available pretty much from day 1.'
