The next best thing to video of new atmospheric nuclear tests is previously unseen film of old nuclear tests. Sure, it’s not even close… it’s patently obvious that new atmospheric nuclear tests is something the United States needs to do, but I guess we’ll just have to take what we can get.
Lawrence Livermore National Labs has embarked on a project of finding and scanning and digitally restoring up to ten thousand films of above-ground nuclear tests. This is being done partially for the historic aspect, but mostly because nuclear weapons designers today have nothing to go on *but* old data, so, the more data they have, the better.
LLNL has set up a YouTube playlist of some of these.
And this one. HOLY CARP, this one.
