This 1957 video is pretty scary. 5 US Army guys volunteer to stand under an A-Bomb

FROM NPR "On July 19, 1957, five Air Force officers and one photographer stood together on a patch of ground about 65 miles northwest of Las Vegas. They'd marked the spot "Ground Zero. Population 5" on a hand-lettered sign hammered into the soft ground right next to them. As we watch, directly overhead, two F-89 jets roar into view, and one of them shoots off a nuclear missile carrying an atomic warhead. "They wait. There is a countdown; 18,500 feet above them, the missile is detonated and blows up. Which means, these men intentionally stood directly underneath an exploding 2-kiloton nuclear bomb. One of them, at the key moment (he's wearing sunglasses), looks up. You have to see this to believe it." http://goo.gl/9zEkw
