The slur on the driving/flying skills of all extra terrestrials was lifted today – first findings from the forensic examination of the damaged windmill bits are that it definitely wasn’t a collision of any kind. That lets the MOD off the hook too.
We’ve just had the interim report from ENERCON, the manufacturer of our wind turbines, and they say that they found ‘classic signs of fatigue failure’ in the ring of about 30 bolts, that usually hold the blades on.
Interestingly though they’ve ruled out material or other defect in the bolts themselves, judging that the bolt fatigue is more likely ‘effect’ than ’cause’ of the blade loss.
The attention has shifted now to the components on either side of the ring of bolts, the theory being that a failure somewhere else in the chain of components is at the root of things.
We’re expecting a final conclusion in a couple of weeks and hope to be able to publish the report in full here.
Meanwhile it’s sad but true to say it looks like we’ve not been visited by beings from another planet (unless you count the Sun reporters… 🙂 ) and it wasn’t some kind of kill crazy flying tank from the MOD. A rather more mundane everyday kind of explanation appears to be emerging.
BTW this also means it wasn’t, def wasn’t, some kind of ball lightning or plasma – and of course not ice falling in cow sized lumps…
Shame in a way, the truth seems rather tame by comparison.
