it could be ice damage, though that would be absolutely a freak occurrence.  I'm somewhat sceptical that it was an UFO, more likely a convergence of Ley Lines, is what we usually find at the end of the day, or the rainbow.   I'm not ruling out a cow dangling from a black helicopter, but i'm categorically ruling out a cow jumping or flying that high.  Unless it was a one horn cow, then all bets are off.
