 In its quest for Cold War military superiority, the United States detonated more than 1,000 nuclear weapons. 
  
 Government researchers blew up many of the bombs on the ground and others in ocean atolls. Yet as threats moved into space and concerns increased about fallout — soil and other material that's sucked into a blast and becomes radioactive — the US exploded 210 of the terrifying devices high in the atmosphere. 
  
 Thousands of films of such blasts, made from 1945 through 1962, were analyzed and locked away in high-security vaults. It's likely no one has seen the footage for decades. 
  
 But on March 14, after more than 55 years of collecting dust, the US declassified 750 of the high-speed films — and released dozens of the digital scans on YouTube. We first heard about the movies from the writer Sarah Zhang on Twitter. 
  
 A team of Lawrence Livermore National Laboratory scientists led the rescue effort over the past five years. The films are made of nitrate cellulose and slowly decompose in the air while releasing a vinegar smell, according to an LLNL release. 
  
 "This is it. We got to this project just in time," Greg Spriggs, a nuclear-weapons physicist at LLNL, said in a video about the digitization effort. "We know that these films are on the brink of decomposing, to the point where they will become useless." 
  
 The project isn't just about shedding daylight on the controversial start of the nuclear age. 
  
 Spriggs said it's also about getting lost data about high-altitude test blasts, which are prohibited around the world by the Comprehensive Nuclear-Test-Ban Treaty yet poorly understood. (The US, however, has yet to officially sign the treaty.) 
  
 "We don't have any experimental data for modern weapons in the atmosphere," he said. "The only data we have are the old tests, so it gets a little bit more complicated." 
  
 The data may help researchers better understand the effects of nuclear explosions and manage the thousands of the weapons in the US's stockpile. 
  
 "We found out that most of the data published was wrong," Spriggs said. "We decided we need to re-scan and reanalyze all of the films."

 About 10,000 of the movies were made, at speeds of thousands of frames per second to slow down fast-expanding explosions. 
  
 However, it took LLNL roughly five years to locate about 6,500 of the films, then digitally scan 4,200 of those. Spriggs said that, so far, the team has reanalyzed between 400 and 500 films. 
  
 Jim Moye, a rare-films expert and movie-industry veteran, helped scan and archive the footage. 
  
 "It is going to be gone at some point, and we don't have forever to do this," Moye said in the video. 
  
 The project is important to "help certify that the aging US nuclear deterrent remains safe, secure, and effective," LLNL wrote in its YouTube video description. 
  
 Spriggs said the team was learning new details about the detonations — lessons he hopes to pass on to future generations. 
  
 "It's just unbelievable how much energy's released," Spriggs said in the release. "We hope that we would never have to use a nuclear weapon ever again. I think that if we capture the history of this and show what the force of these weapons are and how much devastation they can wreak, then maybe people will be reluctant to use them."

 From 1945 until 1962, the United States conducted 210 atmospheric nuclear tests—the kind with the big mushroom cloud and all that jazz. Above-ground nuke testing was banned in 1963, but there are thousands of films from those tests that have just been rotting in secret vaults around the country. But starting today you can see many of them on YouTube. 
  
  
  
 Lawrence Livermore National Laboratory (LLNL) weapon physicist Greg Spriggs has made it his mission to preserve these 7,000 known films, many of them literally decomposing while they’re still classified and hidden from the public.

 According to LLNL, this 5-year project has been tremendously successful, with roughly 4,200 films already scanned and around 750 of those now declassified. Sixty-four of the declassified films have been uploaded today in what Spriggs is calling an “initial set.” 
  
 “You can smell vinegar when you open the cans, which is one of the byproducts of the decomposition process of these films,” Spriggs said in a statement to Gizmodo.

 “We know that these films are on the brink of decomposing to the point where they’ll become useless,” said Spriggs. “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.” 
  
 It’s a race against time, and Spriggs figures it will take at least another two years to scan the remaining films. The declassification of all the remaining 3,480 films, a process that requires military review, will take even longer. 
  
 “It’s just unbelievable how much energy’s released,” said Spriggs. “We hope that we would never have to use a nuclear weapon ever again. I think that if we capture the history of this and show what the force of these weapons are and how much devastation they can wreak, then maybe people will be reluctant to use them.” ||||| Between 1945 and 1962, the United States conducted over 200 nuclear tests up high in the atmosphere to learn about the power of nuclear weapons. The terrifying explosions were filmed from every possible angle and distance, and the movies — an estimated 10,000 of them — were then stored in high-security vaults scattered across the country. 
  
 Now, for the first time, about 4,200 of thee films have been scanned, and around 750 have been declassified by the US government. You can watch about 60 of them on YouTube. Some are in color, some in black and white, and all of them bear the whimsical names of top secret missions: Operation Hardtack, Operation Plumbbob, Operation Teapot. 
  
 The project is spearheaded by Lawrence Livermore National Laboratory (LLNL) weapon physicist Greg Spriggs, who’s hoping to save the films, reanalyze them, and squeeze every bit of data out of them. In fact, there’s still a lot we don’t know about the effects of high-altitude nuclear blasts, and right now they are prohibited by the Comprehensive Nuclear Test-Ban Treaty. By making the movies public and analyzing them, Spriggs hopes to help other nuclear weapon physicists learn more about nuclear explosions. 
  
 "We don't have any experimental data for modern weapons in the atmosphere,” Spriggs says in a video about the project. “The only data we have are the old tests, so it gets a little bit more complicated.” 
  
 Spriggs has so far reanalyzed about 400 to 500 films over the past five years. It’s key to digitize them because they’re made of old cellulose acetate, so they decompose over time. "You can smell vinegar when you open the cans,” he said in a statement. "We know that these films are on the brink of decomposing to the point where they'll become useless.” 
  
 Declassifying the films is a “huge bureaucratic undertaking,” writes Sarah Zhang in Wired. For each film, Spriggs has to fill out a form that then goes over to the Department of Energy for approval. The nuclear test operations are already known, so there’s no reason to keep the films secret, Spriggs tells Wired. It just takes a ton of time to declassify them. Thanks to Spriggs, and his time, we can now enjoy these explosive videos. |||||

The US government has about 10,000 films of the 221 atmospheric nuclear tests conducted between 1945 and 1962, covering the destructive power from all sorts of angles and distances, Business Insider reports. But until recently those films were literally rotting away in top-secret storage. Gregg Spriggs, a weapons physicist at the Lawrence Livermore National Laboratory, tells Paleofuture the films were "on the brink" of being "useless." Not anymore. Spriggs has scanned 4,200 of the films to digital and gotten 750 of them declassified. And this week he posted 65 of the films—an "initial set"—to YouTube. "I think that if we capture the history of this and show what the force of these weapons are and how much devastation they can wreak, then maybe people will be reluctant to use them," Spriggs says. He isn't just preserving the nuclear test footage for historical purposes but to learn as much as possible from it scientifically, the Verge reports. Atmospheric nuclear testing has been banned since 1963, and these old films represent some of the best data available for scientists in the present. Spriggs' laboratory has found about 6,500 of the test films. He says it will take two years to digitize the rest of them and many more years after that to get them declassified.
