An investigation suggests an explosion and fire inside a Nebraska wind turbine was caused by a "foreign object". ...the "object" blew into the turbine causing the blast.

Three investigative teams will be coordinated to learn the cause of this week's fire atop a 260-foot wind turbine north of Bloomfield, the state fire marshal's office said Thursday. The fire occurred at one of 27 turbines on the 80-megawatt Elkhorn Ridge wind farm under construction. Once completed, Elkhorn Ridge will become Nebraska's largest wind farm. ...Meanwhile, work has been suspended at the wind farm, Roberts said.

An explosion and fire at a wind farm under construction in northeast Nebraska has injured three workers. One man, who was atop a tower when a turbine exploded, received first- and second-degree burns in the fire Tuesday morning. Two others, who were nearby, were treated for smoke inhalation and released.
