A US Bomber Once Dropped Four Nuclear Bombs on Accident Over Spain

On January 17, 1966, a B-52 bomber collided with KC-135 jet tanker over Spain’s Mediterranean coast, dropping three 70-kiloton hydrogen bombs near the town of Palomares and one in the sea. It was not the first or last accident involving American nuclear bombs.


The bomber was returning to its North Carolina base following a routine airborne alert mission along the southern route of the Strategic Air Command when it attempted to refuel with a jet tanker. The B-52 collided with the fueling boom of the tanker, ripping the bomber open and igniting the fuel. The KC-135 exploded, killing all four of its crew members, Palomares-Nuclear-bomb-incident but four members of the seven-man B-52 crew managed to parachute to safety. None of the bombs were armed, but explosive material in two of the bombs that fell to earth exploded upon impact, forming craters and scattering radioactive plutonium over the fields of Palomares. A third bomb landed in a dry riverbed and was recovered relatively intact. The fourth bomb fell into the sea at an unknown location.

Palomares, a remote fishing and farming community, was soon filled with nearly 2,000 U.S. military personnel and Spanish civil guards who rushed to clean up the debris and decontaminate the area. The U.S. personnel took precautions to prevent overexposure to the radiation, but the Spanish workers, who lived in a country that lacked experience with nuclear technology, did not. Eventually some 1,400 tons of radioactive soil and vegetation were shipped to the United States for disposal, while 33 U.S. Navy vessels remained at sea in search of the lost bomb. It was later to be recovered on April 7 by a sub, after a Spanish fisherman led the investigators to the vicinity – damaged, but all intact.
