After two planes collided, three hydrogen bombs hit a Spanish village, and one fell into the sea nearby. Two years later, villagers talked to the BBC about the terrifying accident.

A bomber carrying the bombs crashed into its refueling jet causing the disaster. Two of the bombs’ parachutes didn’t open and the explosives around the nuclear core exploded scattering radiation across the countryside. The U.S. and Spain reached an agreement to clean up the soil, but it still hasn’t been done.
