They just don't build them like they used to. Above you see a U.S. Energy Department photo that's been well-circulated around the internet showing the shell of a house that endured the Apple II nuclear test, a 29-kiloton shot fired today in 1955. The building was part of Survival Town, a collection of homes, fallout shelters, power systems, and communications hubs erected in the Nevada desert to gauge the effects of nuclear explosions on civilian structures. The effect, predictably, was catastrophic, but this one lived through it. With a little effort it could become a nice Airbnb. 

This photo shows the crater made by the Sedan nuclear test, also known as the Storax Sedan test, which happened today in 1962 as part of Operation Storax. The crater is the result of an explosion that displaced twelve million tons of earth, and at 320 feet deep and 1280 feet in diameter is the largest man-made crater in the United States. It's also—bizarrely we think—listed on the National Register of Historic Places, especially weird when you consider that it sent two radioactive plumes wafting northeast from the Nevada explosion site, cross country from state to unsuspecting state, to settle especially heavily upon Iowa, Nebraska, South Dakota, and Illinois. Of all the nuclear tests conducted in the United States, Sedan ranked highest in overall activity of radionuclides in fallout, distributing nearly 7% of the total amount of radiation which fell on the U.S. population during all of the nuclear tests at the Nevada Test Site. Historic indeed. You see the explosion that caused all that below.

This photo shows the debris cloud of the nuclear test Priscilla, which was part of the series of tests codenamed Operation Plumbbob, conducted during the summer and autumn of 1957 at the Nevada Test Site. For this particular blast, more than seven hundred pigs were garbed in suits made of different materials to test various means of protecting living tissue from thermal radiation. Guess what? It didn't work. The pigs survived, but with third-degree burns over 80% of their bodies, making for one of the cruelest, but undoubtedly most mouth-watering nuclear tests in history.

In the photo above, department store manager Hillman Lee checks out a group of battered mannequins he had helped the U.S. government use in a nuclear test. The mannequins were placed inside House No. 1 at the Nevada Proving Grounds and subjected to the blast effects of the sixteen-kiloton shot codenamed Annie, which was part of Operation Upshot-Knothole. The images below show up on all sorts of websites identified with all sorts of tests, but these come from the Nevada Department of Energy website and are identified there as the actual House No. 1 thatwas blown to smithereens along with Hillman’s mannequins (those may seem in strangely good shape to you, but keep in mind that fiberglass melts at about 37,000°F, whereas human flesh burns at about 120°F and melts shortly thereafter).

For an interesting indication of the bizarro world some people lived in during the nuclear 1950s, consider this quote from Hillman concerning the use of mannequins (which, by the way, he dressed differently as a tribute to American individuality and choice): “The outcome of this test is unpredictable, but the results of the evaluation may be a powerful factor in deciding fashion trends in the years to come.” That’s right—he thought he could learn from the test how to make nuclear blast-resistant clothes, market them, and make money selling them. Kind of makes you wonder whether humans are simply destined to fail on this planet, doesn’t it? Nuclear test Annie occurred at 5:20 a.m. today in 1953. 

Note: We got an e-mail, and the question was whether the mannequin photo was really made after the test, or before. If the photo were larger you'd be able to see that the mannequins are, in fact, a bit battered. Of course, that raises the question of whether they're radioactive. Being the morbid guys we are, we did check historical records on Hillman Lee to see if maybe he developed health problems, but there's nothing on him. Presumably he made a fortune on his nuke resistant garments and retired to a life of quiet but comfortable obscurity. Or not.

The De Baca nuclear test was part of Operation Hardtack II, a series of thirty-seven Nevada Test Ground blasts squeezed into seven weeks in order to beat a looming deadline—the beginning of a U.S./U.S.S.R. nuclear moratorium. The test ban failed when the Soviets began testing again three years later, a political crisis precipitating that failure, specifically a showdown concerning the status of East Berlin.

The test ban would have failed anyway, though, as all test bans have failed, and all future test bans will fail, because nuclear weapons are seen by weak nations as the ultimate defense against invasion by stronger nations. And of course, they’re right. Since only the year 2000, nuclear-armed nations have invaded non-nuclear nations nine times. Conversely, since the dawn of the nuclear era in 1945, a period comprising nearly seventy military encroachments, no nuclear nation has had its mainland invaded.

That's the entire uncomplicated why of nuclear weapons. There may be periods of relative inactivity, but as time goes by more nations will build them. Nuclear disaster has no choice but to follow one day. There are two scenarios for survival—either all the nuclear nations agree to reduce and eventually dismantle their nukes, or one nuclear armed nation comes to dominate all the others. Guess what? The second scenario isn't going to happen. Not ever. The De Baca test occurred today in 1958. 

This debris cloud was generated yesterday in 1952 by the nuclear blast codenamed Dog, which was part of Operation Tumbler-Snapper, a series of tests that occurred at the Nevada Test Site that year. The people you see in the image are just a few of the 2,100 marines who observed the explosion. Last month Chatham House released a sobering nuclear study showing that there have been thirteen incidents since 1962 that qualify as “near use” of nuclear weapons. In two of those—the famed Oleg Penkovsky incident and the less famous but more serious Stanislaw Petrov incident—nuclear holocaust may have been averted only because individuals disobeyed orders. Chatham House also details many instances of “sloppy practice.” Two examples: President Jimmy Carter once left the U.S. nuclear launch codes in a suit that was taken to the dry cleaners, and in 1981 when Ronald Reagan was shot, his bloody pants containing the launch codes ended up in the hands of FBI agents who had no authorization to possess them. There are instances of sloppy practice from as recently as 2013. If you’re in the mood for some sobering reading, the report is here.
