Nutty:
"What a load of over the top bollox"
Except when the Nimrod AEW dragged its 150ft trailing wire aerial across the A15 a good few years ago at Waddington, and the Vulcan Tanker that did the same a couple of years earlier (Hope the photo shows). I suppose that it is fine for the spotters to take their risks, but they have little consideration for the aircrew in the aircraft that hits them!
