That really stinks FS, I echo all the thoughts of the others and wish you a speedy and happy resolution, and a slow and horrible retribution to the b@ast@rds concerned.
When I used to visit Redhill as a kid, what sticks in my mind most (after the treasures in the Tiger Club hangar; and my thanks to the people therein who were always glad to see us!) was the horribly efficient airfield security guard (has my mind added Jack Boots to the image unfairly?) who would order us off the airfield pronto. Is that level of security now absent?
I can recall an arson attack on a Rallye at Biggin a couple of decades ago - is overnight vandalism at airfields more common now, or is this a (fortunately) rare occurence?
