THE BURNED OVER DISTRICT

Fifty years ago the US Air Force dropped 4 nuclear weapons upon the southern Spanish coast by accident.In an effort to clean it up as fast and as quietly as possible, they rounded up every available warm body on their Spanish bases and bussed then to the site the clean up the mess.

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.”

In the decades since, the Air Force has purposefully kept radiation test results out of the men’s medical files and resisted calls to retest them, even when the calls came from one of the Air Force’s own studies.

Many men say they are suffering with the crippling effects of plutonium poisoning. Of 40 veterans who helped with the cleanup who The New York Times identified, 21 had cancer. Nine had died from it. It is impossible to connect individual cancers to a single exposure to radiation. And no formal mortality study has ever been done to determine whether there is an elevated incidence of disease. The only evidence the men have to rely on are anecdotes of friends they watched wither away.

Air Force personnel obeying orders and covering up their service's embarrassment with their lives. And with villainous zeal denying the troops and the locals any real follow up to help deal with the poison from the sky. I remember Palomares and at the time all the attention was focused on the one bomb that fell in the water. Everybody worried that it might go off or the Russkies might snatch it. Nobody considered that it might just be a distraction from the dangerously sloppy clean up efforts on land.
