That was a very small 1 kiloton yield device, not a megaton range thermonuclear device. Small yield devices do create claps, while thermonuclear megaton-bombs create a super heated column that keeps sucking air from the bottom into the rising stack. That's where the roaring comes from. So much air is sucked up in a such a period of time that there is range where people and animals will suffocate and lose consciousness from lack of oxygen. From there, it only gets worse.

They obviously did that because the sound is of course fake. The few people we can still see at the bottom show absolutely ZERO reaction whatsoever to the sound - because there was no sound at that moment. If the camera hadn't panned up, it would've been even more obvious the audio was fake. The reason the camera didn't pan up higher than it did is because the lower portion wasn't meant to be seen later, either intended to cropped away in the final editing of the tape or simply expected to not be visible on a TV (a bit of the image is lost on a CRT) or a film projector (which can limit the area that's projected/viewable). The 100% full frame area of a film tape is almost never intended to be shown later. So while it may look like the guy filming (who had been told to pan up - so the fake audio could later be applied when the people weren't in view) didn't pan up quite enough, from his perspective he actually had panned up enough because _within the area of the frame which he was focused on_ the people were no longer in view.

Well, if it's from 1955, it _looks_ like Teapot Wasp. The yield would be right, and the mushroom cloud not only looks generally similar (with the large gap between the cloud and the stem), but the glowing spot in the lower-left corner of the cloud at about 0:37 looks very close to a spot I'm seeing in another film clip of the Wasp test that I've found online. (Which is much zoomed in, in color, in better quality, and a slightly different angle)

If it was in 1955, this shot would have been part of Operation Teapot. But I can't find any info about any shots open for public viewing.

I've seen 3 including this one and they all definitely have that initial Bang like a really loud gun which overwhelms any reverberation you'd probably hear if you were there in person especailly due to their crappy audio recording quality back then. This one is the least impressive, it's quite far away and seems relativley low yield. There's another black and white one from the 50s, can't remember the series or test name, its pretty good compared to this. And the other one that sure seems to have real audio is a short documentary of the British grapple x test, (their first h bomb). It's on here somewhere and it's the best example of the sound that I've found if it's real, it even show crowds of dudes all duck at the same time when the wave comes through

The audio needs to be cleaned up... However, good video of the explosion sound.

The dust cloud drifting towards the men is pretty eerie. Why would they send the bomb off upstream from them?

Tiny little firecracker of a bomb.

All witnesses accounts of nuclear explosions, that I have read, describe the sound being more of a short sharp "Pow", than a fat loud "booom". Two videos now seem to confirm this.

Not much of a 'bang' though, considering it was a nuke, huh? Sounded more like a door getting slammed shut!!!!!!

The sound obviously isn't real. The recording of the sound may very well be real, or the sound we hear may at least be a recording of a real explosion of some sort, but the sound was obviously added on later. Hence why the cameraman was instructed to pan up so the audience watching the later wouldn't see the total lack of reaction amongst the crowd.

Prevented the invasion of Japan. which would have probably cost millions of lives. I can imagine the threat of nuclear weapons has kept several countries at Bay from doing wild things throughout our history. But I can imagine at some point these weapons will be used to kill millions, if not billions. A nuclear weapon in my opinion is neither good nor bad.
