Cheers Dave.
It's run entirely by volunteers and their budget is made up of public donations with no local government funding. They had a small number of local businesses sponsor some of the display teams and when you compare that to all the other shows in the UK, its some feat!
The RAF events team love this venue so the reason why they supplied nearly their entire set of display teams for the show.
Also, unlike most other airshows in the UK, this one is also free to the public.
Incredible achievement and it is only going to get bigger and better.
