RAFEngO, thank you. That is one huge expense for an open air event subject to weather. As I said, I have never paid to attend an air show as I have either participated, worked at, or organised.
As Oberon has said, the shows are becoming pretty flat with fewer and fewer military types to call on and stretched budgets fior the international display teams. September might be a bonus if the dates tie in with hosting a major NATO exercise.
The Reds might also be able to call in some favours.
