Let's be fair .... how can any display organiser, first of all ban anyone from being under the display area ??
It's impossible to sterilise the area under a Flying Display off-airfield. CAA Permissions given to displaying pilots state that the aircraft "shall not fly over buildings or vessels which the commander belieives to contain persons", or words to that effect. So at Little Migginton village fete, the displaying aircraft shouldn't be flying over the local WI hall..
On an airfield, things are different.. The Live side of the Flying Display can be cleared of all unnecessary persons. Take Duxford as an example. ALL visiting aircraft are parked under the display, but all the occupants MUST retire to behind the crowd barrier during the display. If there is an accident, then the live side is designed to contain the impact to an area that is as far as possible, free of people, and will not involve the publis who have paid to watch.
Those cheapskate freeloaders who gather on the southern boundary at Duxford, are normally warned by the Police that they are in a risky position, and the landowner has a duty of care to those people in the event that one of them gets an aeroplane parked on his/her head, especially if he charges them. But they have a right to be there and cannot be moved.
