The U.S. National Archives has digitized footage of an atomic blast which took place at Yucca Flat, Nev., on March 17, 1953. The footage has just been uncovered by science historians, including Alex Wellerstein of the American Institute of Physics.
He explains that the video is remarkable because it is one of the only archival videos of a nuclear blast in which the audio has not been edited or overdubbed with stock sound of an explosion.

"Most films of nuclear explosions got dubbed. If they do contain an actual audio recording of the test blast itself (something I'm often suspicious of -- I suspect many were filmed silently and have a stock blast sound effect), it's almost always shifted in time so that the explosion and the sound of the blast wave are simultaneous," he said.
