Never-before-seen Cold War videos released

At the height of the Cold War, the united states was testing nuclear weapons in the event that it is necessary to use them. Now, videos of the remarkable images have been released, with more than 250 videos detailing how extensive the testing was.

The Lawrence Livermore National Library (LLNL) in California has placed the videos on his YouTube channel, all of which have now been released, and show numerous explosions that took place on the testing grounds in the US from 1945 to 1962.

LLNL) and the weapon physicist Greg Spriggs said that it was necessary that the team recovery of the images, a process that lasted five years.


“We know that these movies are on the point of to decay to the point where they become useless,” Spriggs said, according to the Daily Mail.

Spriggs added that it took several years to track the images. Only after the images were found, the LLNL researchers realize that most of the information about the tests was wrong. With less advanced technology at their disposal than their modern counterparts, scientists are reportedly struggling to get an estimate of the explosions’ size and strength.

In total, there were 210 nuclear weapons tests that took place during the 17-year period, the laboratory noted. The lab added that nearly 10,000 of the movies “was not active, spread across the country in high-security vaults.”

“The goals are for the preservation of the films of the content before it is lost forever, and provide better data to the post-testing-era scientists who use computer codes to help declare that the ageing U.S. nuclear deterrent remains safe, secure and effective,” LLNL said on his YouTube page.

“By watching these films, we found a lot of different pieces of information had not been analyzed back in the 1950s, and we discover new things about these detonations, which have never been seen before,” Spriggs said. “We decided to try and re-analyzing the films and come up with better data to better understand nuclear weapon effects.”

There is still images of the blasts that took place during the period that is classified, but only because the yield size is never released to the public. Included in the images, the Operation Plumbob, a series of tests that occurred between May 28 and Oct. 7, 1957 at the Nevada test site. Operation Plumbob is generally considered to be the most controversial test series under the experts.

Other tests are included in the images are Operation Hardtack I and Operation Hardtack II, as well as the Operation Dominic and countless others.

The majority of the tests took place in the Pacific or in Nevada, the lab noted, but there is still significantly more images to be analyzed, with Spriggs, stating that only 6,500 films are to be found, and only 4,200 scanned.

“Of that number we have probably analysed about 400 or 500 of these films,” Spriggs said, according to the e-Mail.
