Light Travelling Faster Than Sound

"Most films of nuclear explosions are dubbed
. If they do contain an actual recording of the test blast itself.........it's almost always shifted in time so that the explosion and the sound of the blast wave are simultaneous. This is, of course, quite false: the speed of light is much faster than the speed of sound....." Unearthed recently from some Russian archive, this document of a nuclear detonation is one of the few films
of its kind that includes a recording of the audio. The sound is not what you might expect.
