"My Favorite Museum Exhibit": Two nuclear bombs, slightly dented

Earlier this week, I challenged readers to send me photos of their favorite museum exhibits and specimens, preferably from museums that might go overlooked in the tourism pantheon. Over the next few days, I'll be posting some of these submissions, under the heading, "My Favorite Museum Exhibit". Want to see them all? Check the "Previously" links at the bottom of this post.

Mike Anderson sent in this photo from the National Museum of Nuclear Science and History in Albuquerque, NM. The museum is home to two (now de-weaponized) nuclear bombs. In 1966—back when these bombs were actually capable of exploding—the United States Air Force accidentally dropped them on Spain.

The accident happened when the plane carrying four of these Mk28 type hydrogen bombs collided with another plane during a mid-air fueling. One bomb fell into the ocean and was eventually recovered. The other three landed near the village of Palomares in southern Spain. Two of the bombs actually detonated—sort of. Only the non-nuclear explosives went off, turning them into what we'd call "dirty bombs" today. Some 650 acres, a little more than a square mile of farmland and rural communities, were contaminated. The U.S. military ended up excavating 1,400 tons of soil from this area and shipping it to the United States for disposal.

You can read an oral history of the cleanup effort. The Brookings Institution has more detail on exactly what happened during the accident and its aftermath.
