Physicist Declassifies Rescued Nuclear Test Films (llnl.gov)

Eloking quotes a report from Lawrence Livermore National Laboratory: 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 LLNL YouTube playlist.

    (OP) Almost all of the nuclear tests that involved delivery of a "payload" (i.e. not underground) were conducted by the Defense Nuclear Agency (under the Department of Defense). The Atomic Energy Commission technically owned the bomb cores but not the bombs proper which were still under the control of the military, along with the planes that delivered them (that got a little fuzzy after the "pits" could not longer be removed... I think that started with the Mk 6). Granted, several of prototype bombs were not weaponized (Ivy Mike had a small refrigeration plant attached to it) but they were still managed by the DoD. Here's a link to the DNA's Ivy brief (for Ivy Bell's, Ivy Mike, etc.).

    So we're probably both right. The tests were under the DoD/DNA and they definitely would have had to approve release but the DoE/AEC almost certainly had to sign off as well.

    Ahh, the ole Bush helped the Nazis kill jews bit.

    Yes, that old bit, in which it is revealed that Prescott Bush could not possibly have not known what he was doing. In fact, a number of corporations willingly cooperated with the Nazis. Without their assistance, the axis could not have made war effectively. Naturally, every one of these corporations has tried to disclaim responsibility for what their German divisions were up to, but the ongoing relationships between such entities during the war make that difficult. The service contract for the concentration camp management machines was paid straight to IBM's American operations in Armonk, NY, for example.

    It is a fact (simple or not) that American interests willfully and thus traitorously aided the axis for profit. And it is a fact that Prescott Bush was among them.

    No reason to point fingers at the US exclusively. (though it is fashionable to).

    That's not what that statement was doing. That statement only took issue with giving a technology credit for something it hadn't accomplished. I point fingers at the US because I live here, and thus I have ready access to information about what we've done. If I knew more than a couple of words of German,* maybe I'd be reading their websites and figuring out e.g. who owned the newspapers in Germany when Hitler rose to power, how they covered him and why, etc etc. What's interesting in the USA is questions like did we help fund/equip The Holocaust, did we know an attack was coming to Pearl Harbor, etc etc.

    Once Spriggs did complete the first scans and roll his sleeves up for the analysis, he discovered that much of the data published were wrong. All the films would need to be reanalyzed.

    "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."

    I'm pretty sure that's because the FBI pressured them to publish modified information. In recent years they wanted to cut about a third of one man's book on nuclear physics.

    ... but a lot of these seem different. I can't help but think that they were held back because of how terrifying the imagery is. Some in particular (https://goo.gl/PviFuq , https://goo.gl/cl1QlR) look like the bomb is creating a sun on Earth which then begins to destroy the Earth. If these videos were available in the 70's, 80's, or 90s, I think nuclear disarmament would have been a much more attainable goal because the severity of the risk would have been even more understood.

    That, sir, is a matter of opinion, and not a fact. International wars do not happen without the approval of the power elite — the robber barons of the military-industrial complex, the top echelons of international bankers, and the other usual culprits, because it's not possible to engage in such wars without their complicity. It is equally plausible that nuclear war is simply not in the best interests of these individuals any more than wars on their own soil, which is why we have proxy wars in third-world countries instead. Meanwhile, nothing absolutely precludes sufficient nutters getting their hands on enough equipment and information to actually launch one of these bad boys and kick off a nuclear holocaust that reduces humanity to a bunch of naked apes hiding in caves full of shit and eating mushrooms. Not that I have a plan for making all the nukes go away or anything, any more than I have one for making all the guns go away. That's why I have guns.
