Another way of looking at it is that the CAA failed to take any formal action against this display pilot at any stage prior to his retirement.
Somehow I do not get the feeling that the CAA is particularly adept in its role as a regulator. The post-Shoreham changes seem to be limited to making life difficult for professionals already engaged with the process whilst looking the other way when a genuinely rogue pilot crosses their path. If any pilot is suspected of breaching the ANO whilst refusing to engage with the aviation safety system must be reported to the police.
