Why do people hate preservation of history? Like it or not these test happen and pretending that they didn't happen isn't going to change a thing.

to all the people in the comment section who have decided that they all know every answer to every situation and are saying these people are monsters for preserving these films, this isn't a bad thing. just because these films are being rescued doesn't mean world war 3 will break out. it will help with major breakthroughs in understanding nuclear reactions not just for weaponry but also for supplying energy and general knowledge of our universe as a whole. it is never a bad idea to obtain more knowledge.

Thanks for saving an important part of our history.

Thanks for this work. My heart cries to know that STILL A LOT OF MATERIAL remains to rot in some warehouse ... risking to lose it forever. However, a lot has already been done, we hope we can do even more.

This is impressive work and I'm glad to see LLNL take steps to preserve history and science. In a weird way, this may help prevent the desire for future atmospheric testing.

My father is a nuclear veteran! He witnessed the Castle Bravo test on the Marshall Islands. He was on the USS CURTISS. I think it is wonderful that these men are restoring and preserving this films, It is history and we need to see how dangerous these bombs are. His radiation level is over 800%. Yes, I know it is more than 100%, but that is in government documents.

Thank you for the services and making this public, I think the public needs to be able to see this as part of history but also saving what is in them, wether for future weapons projects but also more detailed impact of the dentionations. This along with other classified weapon,vehicle, and space programs need to be given to public knowledge and not have only the government and the elite know this information.

Thank you for your work saving these priceless films of history and information.

Note to self: Stop reading KZfaq comments.

Thank You Mr. Spriggs for bringing these films to the public.

Thank YOU Greg for doing this! These needed the care and attention that you gave them. Again, MANY MANY thanks!

Like others have said, thank you for preserving this history AND sharing it with us. It is also not lost on me that your other goal is an updated analysis of the physics behind these tests. This is the kind of work that keeps history and science meaningful for everyone. Your efforts will not be forgotten!

I remember when I got my copy of the excellent documentary, "Trinity and Beyond" back in 95 or 96. The visceral impact of the video from nuclear weapons tests was overwhelming. I have not become jaded to the awesome power of these films. It is of vital importance that these films be preserved before the film stock deteriorates to the point where the film is lost to history. This isn't promoting the use of nuclear weapons or whitewashing the many deleterious effects from atmospheric weapons tests. These films document the numerous tests conducted by the United States. I hope our species never witnesses the detonation of nuclear weapons again in the atmosphere or above it. What was once a matter of national security during the Cold War is no longer necessary. Thanks to the folks at Larence-Livermore for preserving and sharing these important films that documented a very dangerous time in world history. What good is the past if we don't learn from it?

2,400 FPS. Impressive tech for the day.

This is very important history. Thank you for preserving and presenting it.

Thank you very much, gentlemen. This is amazing.

Excellent, congratulations on the channel.

Thank you for this

So glad you all were able to save all this footage!

Thank you for providing the opportunity for the public to view these historic films. Was there ever any audio? I would love to know what these sounded like. Thank you

many thx for saving these films.

Thanks for doing this. These films *should* be preserved. Those who cannot remember the past are condemned to repeat it... and we do NOT want to repeat using these monstrous devils. Countries like North Korea should be perpetually denied access to nuclear weapons by the rest of the world.

Awesome archive.

Thank you for your work.

Very important that these films and the data is salvaged and saved,.....with lessons from the past, and what we can learn in the future.

Thank you for the preservation work!

Brilliant came across the story About archive film being rescued. So glad they are on KZfaq now.

Dear M.Spriggs and M.Moye. First, thanks for all the hard work put in the restoration of theses films. Will there any other batch of nuclear tests films going to be released on this channel ? It has been 5 years without anything so I was wondering if this project has been canceled or your budget cut. Either way, keep up the good work, whatever project you're working on right now.

awesome works guys.

Kudos to the Mr. Spriggs and his colleagues who took the time to preserve this very important part of history.

Thank You..cool images

LLNL: how about the 1080p versions?

Are we gonna get some more of these? I hope so. Thank you!

I want more of these

Blessings on preserving and utilizing this old material for the great good of man kind. Thank you all working in defense.

Thank you for publishing these. Are they in the public domain?

I think it's​ important that these are shared with the public. To many world events are being altered, changed or even trying to be deleted from history.

Would it be possible to add the distance, lens and ISO into the vids? scale is of course very difficult to judge. The official film Co often added the info. (the mountain lab ?????) thanks, great info great channel

My wife currently works at the Air Force Historical Research Agency. While she doesn't work with nuclear testing footage -- to my knowledge: that would be outside my security clearance and need to know -- she does work with scanning some very old motion picture film and microfilm. Many of these were originally produced in the 1940s and '50s, and have deteriorated to one extent or another. And it's difficult work. You may open a film can to a very strong vinegar smell and portions of the film literally crumbling. But this important work, whether it's about assessing how organizations worked -- or didn't -- or visualizing how weapons separated from their carriers. We need to do these things, and one of the most importaant reasons is to ensure we don't repeat the mistakes of the past. So to all you working at LLNL to preserve and restore these films and capture data that couldn't be at the time, my hat's off to you!

You should have converted them all to 1080p before uploading them to youtube so the youtube compression of the lower resolutions doesn't wreck the video.

What a cool project to be on, that must be awesome...back in my youth when I initially got to college I was a physics major and had a plan in my head to get my PhD. and be a nuke weapons designer, but after I started looking at the rate the undergrad Engineers were being scooped up and the starting salaries they were receiving I changed to Engineering and never looked back, but physics was my first love (a recently retired multi degreed Engineer who worked for America's largest defense contractor for over 30 years).

Some of those rolls appear to be on the verge of turning to dust.

Keep up the great work. God speed!

This man deserves an Award

I see only 65 videos in the linked playlist. Any idea when and where more will be released?

What a cool job with cool gear. I do the same with audio. It's a "blast".

Impressionante, bom trabalho aos envolvidos.

What test is shown in LLNL spot in 2:55? Looks quite strange.

Amazing work, I only hope they take steps to also preserve the originals, and store them properly, as who knows what technology will also be available in the future to analyze the films again. But clearly since thier studies show the original data is wrong, it's most important to rescan them now.

Wow. 10,000 films? That's a big job. I have an old scintillation probe made by EG&G Ortec. It still works too.

I'd like to see a more technical follow-up, somewhere around a post-college freshman physics level. In particular, how were the films previous analyzed incorrectly? How are we are analyzing them now? Are the errors ones of haste, carelessness, mistakes, or later knowledge teaching us? Thanks!

Even nuclear tests had unforeseen scientific benefits like carbon-14 dating that came out of atmospheric tests. Analyzing the tapes again is certainly a good thing if we can learn something new. The More You Know! ☼☼☼

I am interested in the harmonics generated by the explosion (i.e. fundamental frequencies and first six harmonics). Do any of the films have the actual sound of the detonation and its aftermath?

Would the footage be classified public domain by now by any chance?

Hello, what are the copyright conditions for these films?

Did these test cause the sonic booms that we have seen to hear lately? Very interesting on how you saved these film great job!

Why were these seemingly scanned at 360p? It makes no sense. 16mm film at 2400fps is easily able to achieve 1080p or better and 35mm can easily do 4k. If the films were actually scanned at 360p, someone needs to be fired!

Please post video for Operation Plumbbob - Stokes, from August 7, 1957.

Fascinating stuff.

And, will higher res be released?

Great work ! Please do not let it fall into the hands of the Enemy ! Where are the rest of the total 10,000 where did he go?

I have a list that holds 2130 known tests, Some fizzled but most went boom.

name of that song in behind?

Jim is only using nitrile gloves when popping the can?

no audio?

GOOD JOB FOR THISE GUYS!... ONE LESS REASON GO SET OFF SOME MORE....WELL, HUNDREDS OF LESS REASONS...

You need to preserve memories to avoid a bad experience.

OK, who is ready to watch things go kaboom?

Michael Bay's porn collection...

This feels kinda like Man in the high castle.

Project declass and rescue films continues, or not ?

what music ?

Where are the videos?

In another LLL vid he mentions the film speeds and resolutions. 0.1 ISO and 1 micron res. the smallest px is an order of magnitude above this I think.

But where is the thermonuclear film?

6 years ago. Where are all the scanned results?

On the search for the Great American Novel, there is - LEECH MOB - now on audio book, found on this channel. In the early 1990’s, 15 year old Kelly Hayes moves from New York City to Connecticut in search of a simpler and safer life but when the school year begins students, teachers and even the principal consider him an outsider and a trouble maker. Bullied and beaten by the Jocks and the Preps, Kelly finds friendship with other outcasts in school but gets caught up in a world far more complex and dangerous that his urban upbringings had prepared him for.

Great, digitization of media is really important for preservation.

This restoration is vital to our future use of nuclear energy. If we'd had these films years earlier, we might even have fusion-generated electricity today. Also, remembering the awesome power we unleashed to stop WWII will allow future generations to understand what we did not understand until the atomic age had begun. It will help prevent a future nuclear war. Small minds cannot understand this, I suppose.

Background Music??

Transparency at last! Woohoo!!

Nuclear explosions have a dark beauty to them.

are the videos available for download?

Glad these videos are being preserved. Humanity will get the chance in this era to be reminded of the absolute power and destruction these weapons have. One standard nuke can wipe out a city, a few a country, and a few more the planet. Retaliation against a nuclear strike is just as scary. One of the only sound defensive strategies of a nuclear attack is to assure mutual destruction: en.wikipedia.org/wiki/Mutual_assured_destruction A nuclear weapon is a powerful bargaining chip. Once scientists in the 40's realized that Mass = Energy, the whole community knew what that meant. As cultures of people around the world evolve, I really hope for my daughter's sake that these weapons will never be used again. Don't fear these videos- understand them. Knowledge and truth are really the only protectors against the use of one of these planet killers. One example of this type of weapon: The largest nuke made during the Cold War was called the Tsar Bomba. The fireball reached nearly as high as the altitude of the release plane and was visible at almost 1,000 km (620 mi) away from where it ascended. The mushroom cloud was about 64 km (40 mi) high (over seven times the height of Mount Everest), which meant that the cloud was above the stratosphere and well inside the mesosphere when it peaked. The cap of the mushroom cloud had a peak width of 95 km (59 mi) and its base was 40 km (25 mi) wide.[21][22] All buildings in the village of Severny (both wooden and brick), located 55 km (34 mi) from ground zero within the Sukhoy Nos test range, were destroyed. In districts hundreds of kilometers from ground zero wooden houses were destroyed, stone ones lost their roofs, windows and doors, and radio communications were interrupted for almost one hour. One participant in the test saw a bright flash through dark goggles and felt the effects of a thermal pulse even at a distance of 270 kilometres (170 mi). The heat from the explosion could have caused third-degree burns 100 km (62 mi) away from ground zero. A shock wave was observed in the air at Dikson settlement 700 km (430 mi) away; windowpanes were partially broken to distances of 900 kilometres (560 mi).[23] Atmospheric focusing caused blast damage at even greater distances, breaking windows in Norway and Finland. Despite being detonated 4.2 km above ground, its seismic body wave magnitude was estimated at 5-5.25.[9][20] Sensors continued to identify the shockwaves after their third trip around the world.

It's a pity LASL isn't doing the same thing.

Is that first guy GWBush's long lost twin?

My film Professor Rico Long filmed some A Bomb tests when he was in the army.

1. What is depicted on the blue screen at the beginning of each film, and why won't they let us see it? 2. I assume the counter is counting time but where is the decimal point? Please forgive me if these are stupid questions.

why scanned them in low resolution ???, at least a HD1080 or a 4K maybe is the minima , no ?

Porque Aldo tiene guardado ésto?

Why do you make them non-listed? This way people searching for them in the normal search will not find the videos. Not good.

How does one even get a job like this..

Here before this goes viral :)

Does anyone know where the arrow came from in the Castle Bravo Shrimp device test? I've always wondered how that got there. Its kind of like cupids arrow because solid fuel thermonuclear devices are the ones we fell in love with right. No but seriously does anyone know?

These filmed were produced at lookout mountain in Hollywood. All of em.

anyone know the background music ?

I think ~80-95% of people within the approximate radius of an above ground nuclear explosion would think we have crashed into the sun in their final moments. I'd never seen a spherical nuclear explosion before, kind of dumbfounded about the idea of it not being in the shape of a "mushroom cloud".

These scans, which are mostly from 16 mm film, are at most 480p. This is ridiculous. If you're going to the trouble of loading them into a scanner, they should be no less than 1080p. What is this, 1990?

how did that film not get ruined form the light can someone answer plz I always wondered that some film do and others dont

Is there a way to harness the energy emitted from Nuclear blasts? or is there a way to use existing nuclear weapons to power the next space bearing equipment? Is it possible capture a reaction inside of a vacuum and feed it helium atoms to keep it "alive"? These types of question are in my mind everyday. MINI Dyson's Sphere. I believe the when we ignited the first test Atom bomb, was the first actual hostile message we sent to space. How far have the radio signals emitted from that explosion traveled through space?
