A water heater “Took off” because of the thermostat malfunctioned causing the water inside to overheat. The water heater left the basement traveling through the 1st floor, the roof, and another 150 feet into the air before coming back down. (This incident happened in St. Paul in 1991 don’t ask me what made me think of this story, but I think It would have been quit a site, (lmao)
