There’s a point where the blade speed can cause all types of havoc and automatic safeties are supposed to kick in and stop the blades. If they don’t, either the damn thing will come apart or fall down.
That’s not a wind, just a good stiff breeze. Smells like opportunists cashing in on the Green Subsidy or whatever euphemism GB uses for the scam where you get govt grants for green energy bullshit, skim off the cash up front, and go bankrupt a few years later
The incident is right in line with Progs’ tendency to ignore facts, logic and plain arithmetic if it doesn’t suit their template, then blame conservatives for whatever goes wrong [see today's news: Economy Shrinks: Dems Blame GOP]

They set the prop blades to turn at low wind speeds. Spooling it up to 50 mph rpm creates a lot of drag. And w a 6 story moment arm the bolts prolly need to be long enuf so the threads come out the other side of the earth, where they screw on the washer an nuts….Plus, unless the wind hits the prop at a perpendicular angle, you got to figure in the “P-Factor” (…where, say, the downward half of the propellor is generating less lift than the upward half of the propellor…) In a prop aircraft, this is why pilots have to add right rudder when rotating the plane at liftoff speed on the runway.

“I found a pail of unused Nuts, Boss”, said no Union worker ever.
I believe the current term of measurement in Old Blighty is “furlongs per fortnight.”

mebbe it got hit by one bigass bird.
‘Course, since it’s in the UK, it could’a been that they torqued the bolts to the left ‘stead’a right.
(What? Yeah, but in Oz, that’d be “counter-clockwisy tighty, clockwisy-loosy,” woodnit?)
Hey, wait …
any chance the torque specs were in pound-foot rather than newton-meter … or t’other way ’round?

Well, folks, I’m still trying to find me one supporter, one wind power company, one anybody who can quote me a price per KWH of wind power.
Each windmill generates DC, which is then filtered, inverted into a fake AC sine wave which is hard on anything AC, synchronized with the grid sine wave, and then backfed into a transformer stepping the voltage up to whatever the local grid rubs at.
Maybe that’s why all the supporters and wind utilities yell at me when I ask the price.

In an unfolding plot that is part “The Sopranos,” part “An Inconvenient Truth,” authorities swept across Sicily last month in the latest wave of sting operations revealing years of deep infiltration into the renewable-energy sector by Italy’s rapidly modernizing crime families.*

Pity Al Gore was not inspecting that wind generator when it fell over.
I can see him at the top of the six story generator and it starts swaying in the 50 MPH wind.
