I once got bollocked for not painting a brick wall pattern on one side of the hessian skirt of my ESV. Because you wouldn't notice a camouflage box body, cab, and 20KVA if they were sitting on top of a brick wall.
You would never guess its an airfield from above...ever... camo hangers would make a huge difference lol Google Maps
You can see 3 typhoons sat outside the cluster of smaller hangers bottom centre. Perhaps they should be painted in a tarmac camo? (These are the interceptor chaps that wave to the Russians regularly).
