The moment you see this photo you know something bizarre and unique to the 1950s is going on. In what was conceived by Air Force brains as a public relations event, today in 1957 these five men (and the photographer) voluntarily located themselves beneath a nuclear detonation to demonstrate that atomic weapons were suitable for use over civilian populations. Yes, we know—if they don't kill people what's the point? Like we said, bizarre and unique to the ’50s. The U.S. would later design a neutron bomb that was meant to kill only people and leave buildings and infrastructure intact, which makes sense in upside-down military world, but not killing people? We're baffled.

We have no problem admitting they would have lost us at unguided. We wouldn't even be in the same time zone: “Okay, everyone ready? Good, we're counting down from— Hey, where'd those pulp guys go?” Did the test actually prove nuclear weapons were safe? They thought so. All five of the above guinea pigs lived for years beyond detonation day, but in a (not) shocking plot twist, all eventually died of cancer. The photographer, who was stationed a few feet higher than the other men, was incinerated. Oh, nope—actually he died of cancer too. You can watch the test at this link.
