A strange thing happened at a wind farm in the UK. One of their turbines got severely damaged. Assuming it was hit by an object (which, from the damage, looks likely), the object must have been approximately the size and weight of a cow. It is currently unknown what specifically may have hit the turbine.
Therefore, it was an alien spacecraft. A very small, cow-sized one. Drunk driving too, I imagine. Bats can avoid those motherfuckers. Bats rule, but I gotta think interstellar travelers could trump even a bat's navigation systems with their UFO (Ungulate Flying Object).
I figured it out! It was one of these! An undiscovered population of extant pterosaur living in England is way more likely than clumsy visitors from planet Moron.
