We are led to believe that the now infamous UFO crash site site at Conisholme Wind Turbine site is soon to be concluded.
Following the devastating damage caused to the wind turbine back in January of 09 the remains of the wrecked blade were sent to Germany for forensic tests to determine what if any, alien object, collided with the blade so seriously to inflict the sort of damage seen to the 65ft object.
Speculation has been rife around the internet and general media that the damage sustained by this incident must have been from a significantly sized object to render the turbine unrepairable. Early reports suggested blocks of ice falling from aircraft or indeed merely damage sustained through the impact of the downed blade – it is noted however that the wind speeds at the time of the alledged UFO crash were very low meaning the second blade which become detached from the main hub would have been not been the likely caused of the damage.
Ecotricity are due to receive the forensic report in a matter of days and we expect to hear of the outcome very soon thereafter. Updates to this story will be published as soon as they happen…
6th February UPDATE – Looks like the report is being delayed and will not be avaliable until next week, watch this space….
17th March UPDATE – Dale Vincent of Ecotricity has stated on his blog that “The bolts that failed were found to exhibit ‘classic fatigue’ signs (from the forensic testing). The bolts were not the root cause though only a symptom. The root cause has been found, it was a manufacturing/QC defect with regards the blade adaptor, basically the bit that joins the blade to the machine hub. A key part here was out of tolerance, allowing movement that put the bolts under loads outside their design limits.”
