Remember the Twilight Zone episode about the people from a bus stuck in a diner because the road was washed out? And they suspected there was some real funny business going on, possibly even aliens, I believe someone said Venutians?
So a cop starts questioning people and the funny thing was, the real bad guy was working behind the counter, wearing a cap to cover an eye in the middle of his forehead, remember that?
And he was from Uranus!
Well, there were a lot of question marks at first there too, but I think they finally determined the counter guy was a noob alien troublemaker from Uranus and took him out behind the diner and shot him.
I am suspicious of the monsters riding on the wing at 20,00 feet.
