We had something like that happen in Oregon last year.
A tech forgot to set a brake on the blades and they went
overspeed. A blade hit the tower and the tower buckled.

OK, so it's a long link and you will have to cut and paste.

Looks like an overspeed problem. Most likely due to human error in setting
things up:

winning."

Overspeed - agree.
Human error - no evidence.

I'd agree there's no direct evidence for human error in that video. But I
thought that human error was the most likely explanation -- whether it was
in the design, construction, or some human designed system.

What kind of problem, that does not involve a human, do you think might
have caused the overspeed and subsequent destruction?

I suppose a meteorite could have hit the turbine. But I'd guess that would
be a lower probability event than some human error. And I'd be surprised
if that would cause an overspeed (as differentiated from the turbine merely
appearing to blow up).
