There has been quite a few over the UK. Looking on social media there could well have been at least one unit at each regional heat with the possible exception of scotland.
The team from my squadron was the only one in the North of England but we didn’t attend in uniform due to wearing merch with our sponsors logo branded all over it.
Just have the pain staking wait to see how gets to the national final now 
Wishing you, and the other Air Cadet entries, the best of luck!
