Harry Vanderspeigle's spaceship is the spaceship piloted to Earth by the alien who assumed the identity of Harry Vanderspeigle. Vanderspeigle had never intended to land on Earth, his mission being to simply enter atmosphere to deliver a device which would execute the genocide of all humanity. His spaceship was, however, caught in an electrical storm which resulted in a piece of breaking off and he was was forced to land on Earth and assume a human identity to blend in. He is now seeking both the remains of his spaceship and his device, desperate to find both before his presence on Earth is detected. His device is somehow "tethered" to his spaceship in a way that causes the spaceship to decloak and affect electrical devices around it when Vanderspeigle is close to the device.
