How little did we know in 1957. Or maybe we did, and then this is just stupid. 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.
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.
