Sixty-seven years ago, a family living on the outskirts of Hopkinsville, KY made headlines after claiming they'd been visited by "little grey men" after spotting an otherworldly aircraft floating over their farmhouse.

The incident, also called the Kelly-Hopkinsville encounter, referring to the nearby unincorporated community of Kelly, was well documented in the media and pop culture: director Steven Spielberg cited it as part of the inspiration behind such films as E.T. and Close Encounters of the Third Kind.
