A wind turbine at Perkins High School fell apart Saturday.

Ed Sharp was standing on the back porch Saturday afternoon when he heard a sound like a shotgun.

He looked next door, where the three wind turbines at Perkins High School were spinning in Saturday's high winds, to see part of a turbine blade fly off and land in the student parking lot.

Out of balance because of the missing blade, the turbine and its tower began shaking, the remaining two blades banging against 60-foot support pole -- and the 30-foot-wide windmill "just blew apart," Sharp said.
