I suspect the actual first frames are still classified as they likely evidence detonator tech/performance. So the real first moments of the nuclear age will never be shown. (The high-speed cameras would have started filming shortly before the blast.)

Some stunning images, looks like a sun plopped down in the middle of the desert.

One of my big gripes with the film Oppenheimer was the blast itself, obviously a climactic moment in the film.

It looked like someone set off a bunch of chemical explosives. That’s not how it looked in real life. Totally bizarre decision. I don’t know if they were trying to avoid effects on purpose of go gritty and retro or something but the “unearthly cosmic horror” feel of the first a-bomb blast is important. It’s what led Oppenheimer to recite “I am become death, destroyer of worlds.”

> And physicist George Kistiakowsky found himself certain that “at the end of the world—in the last millisecond of the Earth’s existence—the last human will see what we saw.”

I highly doubt it. The last human will likely live many years in agony, fighting disease and starvation.
