||An American B-52 collides with its tanker aircraft during refueling over the town of Palomares, Spain. Seven crewmembers are killed in the resulting jet fuel explosion. Also, three 10-megaton hydrogen bombs crash near the town. Although none of them detonates, two rupture, scattering powdered plutonium over 558 acres of farmland. The USA hauls
away 1,600 tons of soil and tomato plants and disposes of them in Aiken, South Carolina.
