PittsExtra, you misunderstand the scope and purpose of the CAA review. It is triggered by the Shoreham accident, but not dealing with any specific causal factors pertaining to it. It will review all the supervisory, planning and safety aspects of public displays. This approach is measured, appropriate, timely and expected.
I haven't read the latest TOR for the review, but the early concept was that it should, among other things, conduct an exhaustive review to make sure that the regulations include sufficient measures to mitigate risk
in order to reassure the public, but not pre-emptying or impinging on any findings that may or may not later arise from the AAIB investigation.
That is NOT to say that this is
PR exercise. It is not. But it is a necessary step following Shoreham. There are areas that some have questioned in recent years, but not necessarily the ones mentioned by certain posters here. The supervision, mentoring and clearance methods are very tight and well respected.
