Nutloose
And Civi wise you have your own tools. Trust me the best form of tool control is having to pay for them, trust me loosing a screwdriver at over £60 a pop makes sure you don't.
Thats why at a nth yorks ex tonka base you were not allowed to park a tonka (no matter how desperate for space) in a half empty grob hangar. AC under MAA rules cannot be housed with AC under CAA rules because of the very reason of tool control. A rule that seemed to 'fly' out of the window when away from an RAF base.
