Representatives of Lawrence Livermore Laboratories and the film industry are digitizing some of the atomic bomb movies shot on old nitrate film in the 1950s. Several have been declassified and 60 of them are here on a YouTube playlist:

I find these fascinating and, in some cases, beautiful.

Some of the more interesting ones are:

Dominic-Housatonic 120256 and Dominic Harlem- beautiful stellate atmospheric airbursts

Plumbbob-Diablo 41549 and Teapot-Tesla-low altitude / ground burst testing

Teapot Tesla 28652-close up of ground effect from fireball and blast

Plumbob-Rainier 43771-an underground mountain "shot" which produces some visible reduction in the mountain.

This is one of the most frightening recon

If you look closely at the first few seconds, you can see the Mach Stem Effect. The physics is fascinating. But the rest of it all is pretty absurd.

That (Teapot-Turk) was only something like a 24 KT 'shot' too, Wodin. Small potatoes by today's typical warheads.

Never knew that. Interesting.

I believe the largest warhead in the U.S. arsenal is the B83 at 1.2 megatons (1.2 million tons of TNT).

But back in the day, I think USSR was up to the 20-30 megaton range?

I thought the yield was like 9 megatons ? and iirc there was a even larger air-deliverable warhead

Quick search revealed a decent article. I'm sure there are better out there, too:

Growing up in the Sixties, never knew how close we came during Cuban crisis. And never so happy to see the Wall come down, freeing up our brave troops in Europe. But now we have Putin [;)]

Thanks - I think [;)]

I remember seeing this, but forgot the megaton range. My God.

Hi guys, I am watching a special on Smithsonian Channel and they have a one hour special about the blasts in Nevada etc. It's called A - Bombs over Nevada.
