My fear is the aircraft being pushed further away making the spectacle a non spectacle of watching distant dots which will lead to air shows loosing interest as the excitement is a major part of the attraction
There is another important issue for airshow organisers.
If the display is offshore in places such as Bournemouth or Dawlish, how do they get the entrance fees that help pay for the event and to seedcorn next year's? Donations?
Think of what would happen with Fairford if it relied on donations.
