That is some power... When wind speeds are high/to high it turns/twists its blades to reduse speed, it can even stop still in hard wind to protect itself... Eater its a major design flaw in the tower, or the blades didnt turn as they shold and it has gone around to fast and colapsed... (Due to the blades beeing twisted around the base, it guess it has gone around to fast.) Tnx4charingit :)
