I guess that's one of the reason you don't have houses in windfarms!!!

I'll have to watch that at work on the modern computer.
I was amongst the wind farms near McCamey, TX this past week, looking at oil leases.
You don't want to know what the locals call this hill below...
Windmills and oil wells, although it is was brown and dessicated, not lush and verdant, as they are back in a dry spell...

That's what it looks like!!! Reminds you of a very maternal figure.

Windmills have a transmission that keeps them rotating at 60 Hz or 120 Hz. Obviously, the transmission on this one broke. But then, the blades are supposed to feather into a position that would keep that windmill from turning. Maybe this was some kind of test? That could explain why a camera was there.

I did pick something up that I seem to be right about. When I watched it, it seemed like there was an explosion or something.
If you watch closely, the blade actually hits the pole, resulting in breaking of both the blade and part of the pole. The resulting impact throws the other blades off enough that they also impact the pole, resulting in the self destruction of the entire machine. This looks to me like they were testing what exacly would happen if both the transmission failed and the blades did not feather down in the middle of a storm.
The one blade somehow got bent enough that it actually impacted the pole. Perhaps something struck the blade? It shouldnt of just bent in like that, not enough to impact the pole, anyways.

Nothing needs to strike the blade. Vortex shedding can cause the blades to flex perpendicullarly to the axis. Just like a stop sign shaking in a hurricane.
