The U.S. conducted 210 atmospheric nuclear tests between 1945 and 1962, with multiple cameras capturing each event at around 2,400 frames per second. But in the decades since, around 10,000 of these films sat idle, scattered across the country in high-security vaults. Not only were they gathering dust, the film material itself was slowly decomposing, bringing the data they contained to the brink of being lost forever.
For the past five years, Lawrence Livermore National Laboratory (LLNL) weapon physicist Greg Spriggs and a crack team of film experts, archivists and software developers have been on a mission to hunt down, scan, reanalyze and declassify these decomposing films. The goals are to preserve the films' content before it's lost forever, and provide better data to the post-testing-era scientists who use computer codes to help certify that the aging U.S. nuclear deterrent remains safe, secure and effective. To date, the team has located around 6,500 of the estimated 10,000 films created during atmospheric testing. Around 4,200 films have been scanned, 400 to 500 have been reanalyzed and around 750 have been declassified. An initial set of these declassified films—tests conducted by LLNL—were published today in an [URL="https://www.youtube.com/playlist?list=PLvGO_dWo8VfcmG166wKRy5z-GlJ_OQND5"]LLNL YouTube playlist [/URL].
"You can smell vinegar when you open the cans, which is one of the byproducts of the decomposition process of these films," Spriggs said. "We know that these films are on the brink of decomposing to the point where they'll become useless. The data that we're collecting now must be preserved in a digital form because no matter how well you treat the films, no matter how well you preserve or store them, they will decompose. They're made out of organic material, and organic material decomposes. So this is it. We got to this project just in time to save the data."
"When you go to validate your computer codes, you want to use the best data possible," Spriggs said. "We were finding that some of these answers were off by 20, maybe 30, percent. That's a big number for doing code validation. One of the payoffs of this project is that we're now getting very consistent answers. We've also discovered new things about these detonations that have never been seen before. New correlations are now being used by the nuclear forensics community, for example."[/QUOTE]

We need more films of these incredible things, this is amazing.

Does this mean that more nuclear accidents and tests were declassified? Several years ago I found a page on the DOD website with all the tests and accidents(huge page) and while some massive fuck ups were declassified like jettisoning a nuclear weapon a few miles off the US coast in a populated area that was also armed for some reason, there were some very vague pages like all they mentioned was the year, season and ocean it happened so it makes you really wonder how big of a screw up it really was

Nope. Still right off the coast of Savannah, Georgia somewhere in a beach.
[QUOTE=Gen. Crumpets;51969741]Both of these are absolutely terrifying.[/QUOTE]
So i occasionally have nightmares about nuclear attacks (one just this week) because the concept that such a weapon exists, in such massive numbers, completely terrifies me. These aren't weapons of war: they're tools of extinction. Use of one of these says you don't care whether you kill enemy or civilian, and anyone who advocates it completely lacks empathy. It literally destroys generations of people and makes the earth they once stood on unlivable.
It completely astounds me that we have people who don't understand this concept and think nukes are just a sort of catch-all answer to our wars.
Finally more variety for YouTube videos where something explodes.
I hope we don't nuke each other ever [del]in the future[/del].

The issue is you can't uninvent them now that we understand how they work, so while decommissioning them all would be wonderful in theory it'd just pave the way for a madman to wave the threat of nuclear annihilation over us all in order to get their way.
I can't imagine what it must of been like being on the teams that created these. I would feel uneasy the whole time while being in awe of what I made.
[QUOTE=Silence I Kill You;51969877]Nope. Still right off the coast of Savannah, Georgia somewhere in a beach.[/QUOTE]
Probably off Tybee or Hilton Head somewhere.
I've actually got a close family member who knows one of the scientists who worked on the hydrogen bomb and atomic bomb programs (Dr. Ken Ford), and through them have gotten some signed copies of some books by him.
Such brilliant men and women, but at the same time a group of people far more cognizant than most of the sheer existential risk posed by nuclear weapons.

[QUOTE=shad0w440;51970966]Probably off Tybee somewhere.[/QUOTE]
Yup. Still buried under boatloads of silt most likely, but still sitting out there off the coast of Georgia.
Additionally, there was the [url=https://en.wikipedia.org/wiki/1958_Mars_Bluff_B-47_nuclear_weapon_loss_incident]loss of a weapon in '58 from a B-47 crash[/url] and another incident in the South in 1961 when [url=https://en.wikipedia.org/wiki/1961_Goldsboro_B-52_crash]a B-52 carrying 2 Mk39 nukes broke up in midair[/url].
Especially as someone who's quite fond of nuclear energy, it's a shame to see so much of our history with the science of it as a species go to making weapons of mass destruction.

Exactly. It's never going to go away. Never in my life will I be able to go "Man, remember when everyone had doomsday weapons at the ready all the time? Glad we don't have to worry about that anymore." Our president carries the keys to extinction with him at all times.
The reality is hard to imagine, that we possess thousands of these weapons that could just literally erase you in the blink of an eye. It's spooky, to be honest

The thing is, this happened A LOT. The one you guys are talking about is the most well known one but there are a lot of nukes sitting off our coasts.
I wish I could still find that page. If that's any indication, we were our own nuclear threat. I wonder if we nuked ourselves, the government would admit they fucked up and killed millions of people or just fire missiles at the soviets out of embarrassment.
This is actually really important, as we have very, very limited footage of actual nuclear explosions, it's why you usually always see the same clips over and over like the one with the house that gets absolutely obliterated.
How the fuck did they managed to hide that these ever happened?

Turning night into day
Is there a reason why the fireball seems to darken shortly after it forms then brightens before slowly darkening again? It's more obvious in the high speed footage but it can be seen as a quick double flash in the normal speed footage as well.
Reminds me of all those nuclear explosion compilations from the early years of Youtube.
♫ [I]Do you fear this man's invention that they call atomic power? Are we all in great confusion, do we know the time or hour? When a terrible explosion, may rain down upon our land, meting horrible destruction, blotting out the works of man![/I] ♪
Seriously, nuclear weapons are such a weird thing. I'm absolutely terrified of the destruction and disease that they'd bring in the case of a war, but also attracted to the sheer destructive power they are capable of.

They didn't hide that they happened, they just didn't release the high-speed footage as the high-speed footage can be used to accurately calculate yield from the time between the two flashes of light.
