Did the top turbine's blades not feather correctly?   I heard that wind gusts reached 165 MPH  -  at that speed I'm surprised more turbines didn't fail.   I wonder what provision smaller home-type turbines have to deal with high wind speeds.   Do they have a brake, or do their blades feather, or what?

Yes, it's got to be a blade feathering problem - in fact you can see in the photo that the whole turbine head is actually facing the opposite direction to it's two neighbours.

The vast majority, and by far the biggest, of the UK's turbines are actually offshore. Goodness knows what havoc they'll find when the wind farm service boats can put to sea again.

A shameless plug for my business - visit www.magazineexchange.co.uk for back issue magazines - thousands of titles covering cars, motorbikes, aircraft, railways, boats, modelling etc. You'll find lots of interest, although not much covering American buses sadly.

  Not sure about all, but jacobs feather out of the wind after max rpm is reached, about 45 IIRC, becoming fully feathered up around 90 IIRC, at which point a brake is engaged to stop it.
