Did UFO crash into wind turbine?

An investigation is under way into how a blade was mysteriously torn off a wind turbine amid reports of "strange lights" in the sky.

The turbine at Conisholme in Lincolnshire was left wrecked after the incident.

The Sun quoted residents speculating the damage could have been caused by a UFO.

Wind turbine company Ecotricity said it had never seen anything like it before.

A spokeswoman said: "We're conducting a thorough investigation into what happened. This kind of thing has never happened to us before."

The missing blade was found on the ground beneath the turbine, she said, adding that the company could not speculate on the cause of the damage.

"An engineer has been on the site since it happened, early on Sunday morning, and is carrying out a sort of forensic investigation."

The Ministry of Defence said it was not looking into the incident.

A spokesman said: "The MoD examines reports solely to establish whether UK airspace may have been compromised by hostile or unauthorised military activity.

"Unless there's evidence of a potential threat, there's no attempt to identify the nature of each sighting reported."
