The Hopkinsville Goblin Case

In 1955, members of the Sutton family were out on their porch enjoying a relaxing visit/drinking binge with their good friend Billy Ray Taylor. Billy Ray decided to go out and get a drink of water from the well, when shit started getting weird.
He ran back in to tell everyone he'd seen some bright lights in the sky and that everyone should come look. According to one member of the Sutton clan, upon stepping outside the Suttons-plus-one encountered:
"... a luminous, three-and-a-half-foot-tall being with an oversized head, big, floppy, pointed ears, glowing eyes, and hands with talons at their ends. The figure, either made of or simply dressed in silvery metal, had its hands raised."

After seeing these figures coming out of the woods, showing the universal sign of surrender, the Suttons did the only thing they could do: try to kill their asses.

As they shot at the defenseless creatures with rifles, they claim to have heard clangs and ricochets as if the aliens were wearing some kind of metal armor. They said the aliens "flipped over and fled into the darkness when shot at.
