The New York Times reports: Alarms sounded on United States Air Force bases in Spain and officers began packing all the low-ranking troops they could grab onto buses for a secret mission. There were cooks, grocery clerks and even musicians from the Air Force band.

It was a late winter night in 1966 and a fully loaded B-52 bomber on a Cold War nuclear patrol had collided with a refueling jet high over the Spanish coast, freeing four hydrogen bombs that went tumbling toward a farming village called Palomares, a patchwork of small fields and tile-roofed white houses in an out-of-the-way corner of Spain’s rugged southern coast that had changed little since Roman times.

It was one of the biggest nuclear accidents in history, and the United States wanted it cleaned up quickly and quietly. But if the men getting onto buses were told anything about the Air Force’s plan for them to clean up spilled radioactive material, it was usually, “Don’t worry.”

“There was no talk about radiation or plutonium or anything else,” said Frank B. Thompson, a then 22-year-old trombone player who spent days searching contaminated fields without protective equipment or even a change of clothes. “They told us it was safe, and we were dumb enough, I guess, to believe them.”

Mr. Thompson, 72, now has cancer in his liver, a lung and a kidney. He pays $2,200 a month for treatment that would be free at a Veterans Affairs hospital if the Air Force recognized him as a victim of radiation. But for 50 years, the Air Force has maintained that there was no harmful radiation at the crash site. It says the danger of contamination was minimal and strict safety measures ensured that all of the 1,600 troops who cleaned it up were protected.

Interviews with dozens of men like Mr. Thompson and details from never before published declassified documents tell a different story. Radiation near the bombs was so high it sent the military’s monitoring equipment off the scales. Troops spent months shoveling toxic dust, wearing little more protection than cotton fatigues. And when tests taken during the cleanup suggested men had alarmingly high plutonium contamination, the Air Force threw out the results, calling them “clearly unrealistic.” [Continue reading…]
