The damage was caused last month leaving the turbine with only two of its three 22 metre blades
Ecotricity said the most likely cause of the damage was "material fatigue" a report from the company said "Following several weeks of forensic examination of the turbine's components the manufacturer, Enercon, has today ruled out 'collision' as a possible cause. An interim report has concluded that bolts securing the blade to the hub of the turbine failed due to 'material fatigue'."
The UFO crash theories started after locals had reported a large 'smashing' noise while others said they had seen mysterious lights at around the time of the damage to the turbine. The conspiracy was enlarged when Ecotricity were unable to provide an alternative explanation.
