Wind turbine blade falls off again at Elkton-Pigeon- Bay Port

Smith said brief power outages experienced in the area cause the three turbines to instantly stop and recoil, which fatigues the blades in the area where they are likely to break. When the blades are new, they're more flexible and durable. ...we are going to direct all maintenance employees to approach away from the blades and keep visitors away. The blade ejection happens rarely, but we need to err on the side of safety.
