The news has been full of UFO talk in the last day or so, after a giant blade was smashed off a wind turbine in Lincolnshire.
The 290ft turbine near Louth had one blade ripped off and another severely damaged. Locals had reported spotting mystery 'bright flashing spheres' in the sky prior to the incident, sparking a frenzy of speculation.
Like any good mystery, it soon acquired its own catchy nickname. 'The Octopus UFO,' people dubbed it, because of its shape.
When a spokesman for the energy firm which owns the 20-turbine site admitted he didn't have an explanation - and said "the UFO theory is the best one we've currently got" - the 'little green men' believers went into overdrive.
Ecotricity's Dale Vince, speaking on Radio Four, did scupper some of the more outlandish theories, however, by explaining that the blade hasn't disappeared - rather, it was lying on the ground under the turbine.
I chuckled when Mr Vince pointed out that, if it was a flying object, it would have taken something about the "size and weight of a cow".
Call me an old traditionalist, but my money's on mechanical failure. I don't believe in UFOs any more than I believe that crop circles are the result of otherworldy forces.
This freezing weather probably had something to do with it. Or maybe the icy conditions have prompted a surprise visit from extra-terrestrials? Or given cows the ability to fly?
Another theory was a large block of ice falling off an aeroplane. If this was right then it's another good reason for not living under a flight path.
