The RNALF have the right idea, a free airshow every year where they 'show off' their airforce through a series of role demos and imaginative static displays that show off the full breadth of their activities. I went to the one at Volkel when I was on loan to the AAC, and I've got to say it was great. F-16's attacked the base then a formation of Chinook and Cougars dropped off troops, then a C-130 resupplied vehicles / refuelled the cabs. Meanwhile a KC-10 refuelled an F-16, etc.
The kids loved the pyro display, and afterwards they got to sit in, play with most of the kit that had taken part. Good work KLU fellas!
