As I understand it, the system that was engineered to point the array in the
direction of the least amount of wind drag failed and the system corkscrewed
and collapsed the array upon itself.

I offer my condolences to Radio Arcala, but I have a question about that
explanation: shouldn't the engineering of the tower system have accounted
for the possible failure of a windload-mitigation system?
Does anyone know: was it insured?

Apparently the engineering spec called for an automated feature to turn
the
massive array for minimum windload failed, allowing the whole structure
to
"corkscrew" and collapse on itself.
