The Winco -
I had 14 years with the CAA until retirement in 1998 dealing with the operational regulation of private, sporting and recreational aviation. This included the UK's vibrant airshow scene in all its aspects.
I have been actively involved with air displays as a pilot since 1955 and this continues to the present day.
I think if you look back through my posts you will find the answers to your points have already been made. My comments are, of course, personal ones.
Cheers,
