In Stephen King's novel The Tommyknockers, a massive spaceship is discovered in the earth and uncovered by Roberta "Bobbi" Anderson. The eponymous Tommyknockers are a monstrous alien race that possess technological prowess, but are hindered by their species-wide bout of psychosis. They have a corrupting influence on the nearby town of Haven, although their effects and appearances vary in both the novel and its 1993 miniseries adaptation.
