Slow-motion footage of an airburst nuclear explosion hitting the ground

From the newly-released archives.

After collecting dust in high-security vaults for more than 65 years, hundreds of reels of film showing Cold War nuclear bomb tests have been declassified by the United States.

From 1945 to 1962, the United States detonated more than 210 nuclear bombs, with multiple cameras capturing each explosion at around 2,400 frames per second.

There's so many to watch!
