Terminal Turbines?

The news story, carried in the Sun and elsewhere, (http://www.guardian.co.uk/media/organgrinder/2009/jan/08/windpower-thesun) that a 130 foot rotor in Conisholme, Lincolnshire had possibly been destroyed by aliens further illustrates just how easily confused people can be by fast-moving events at a distance. Rather than a creature with tentacles, there appears to have been a firework display in the area, coinciding with metal fatigue in one of the arms of the rotor. The alternative suggestion that an object 'the size of a cow' might have hit and damaged the rotor has thrown up the suggestion that a block of ice from the toilets of a passing plane could be a (disappearing after the event) candidate. There was no evidence of moon-leaping bovines in the vicinity.
