I don’t know how much news coverage this got outside of Spain but it’s still a well-remembered incident here.
Exactly 50 years ago today there was a Broken Arrow incident in Palomares, a small village in the southern Mediterranean coast of Spain.
On January 17 1966, a USAF B-52G bomber collided with the tanker that was refuelling it on air (there’s a nearby American base). Both planes were destroyed and the four hydrogen bombs carried by the bomber fell down. One of them was quickly found intact. Another one fell in the sea and was recovered three months later, after extensive underwater search.
The parachutes failed in the two other bombs, so their conventional explosives detonated on impact, spreading several kilograms of plutonium in a rural area of 1 square mile. A cleanup work followed, during which tons of contaminated soil were removed and sent to the US in barrels. But despite the efforts, a considerable amount of radioactive material could not be recovered.
Since the economy of the area depended heavily on tourism, Franco’s government tried to minimize the incident, to the point that the American ambassador and the Spanish minister for information and tourism swam in the affected beach before the press to try and persuade tourists that there was no danger.
Fifty years later radioactive levels in the area are still higher than normal, and a few months ago an agreement was reached with the U.S. Secretary of State to finish the cleanup of the affected area.
