Erm

Maybe it's me but I found this story rather worrying.

The Ministry of Defence has expressed concerns that some wind farms interfere with military radar, making aircraft flying over the turbines "invisible".

I'm not a military strategist but announcing that our defence early warning system can't detect incoming if they navigate over wind farms does rather strike me as offering them some clues about how to stage an attack. The Thames estuary is now rife with turbines so that might offer an easy approach to the capital (not letting out many secrets here - anyone can see them from Herne Bay). In fact I would imagine that an underhand enemy might trumpet their achievements in meeting the Kyoto targets using large, floating, wind farms and actually be using aircraft carriers camouflaged with radar-defeating windmills.

I know I'm worrying unduly because the MOD have a great record in making sure that important information is held securely.
