January 17 - a B-52 Stratofortress collides with a KC-135 Stratotanker during aerial refueling near Palomares, Spain in the Palomares hydrogen bombs incident. Seven crewmembers are killed in the crash, and two of the B-52's nuclear weapons rupture, scattering radioactive material over the countryside. One bomb lands intact near the town, and another is lost at sea. It is later recovered intact 5 miles (8 km) offshore.
