Stock Photo - Aug 23, 1966 - Palomares, Spain - The 1966 Palomares B-52 crash or Palomares incident occurred on January 17, 1966, when a B-52G bomber of the United States Air Force's Strategic Air Command collided with a KC-135 tanker during mid-air refuelling at 31,000 feet (9,450 m) over the Mediterranean Sea, off the coast of Spain. Of the four Mk28-type hydrogen bombs the B-52G carried, three were found on land near the small fishing village of Palomares in the municipality of Cuevas del Almanzora, Almería, Spain. The non-nuclear explosives in two of the weapons detonated upon impact with the ground, resulting in the contamination of a 2-square-kilometer (490-acre) (0.78 square mile) area by plutonium. The fourth, which fell into the Mediterranean Sea, was recovered intact after a 2 1/2 month-long search. One of the bombs was buried in the garden of Miguel Bonillo, a peasant farmer who was tending his two-acres of tomato plots when it fell. Another was buried behind the church, a third in the hills near the village cemetery.
