in those old videos of atomic bomb tests destroying buildings, how does the camera/footage survive?

Question

I’m referring to those old black and white videos of US atomic bomb tests – it always shows buildings and other constructions being literally blown away but the camera seems fine

Answer 1

It’s inside a small, very rugged and securely anchored enclosure. They’re far enough from the bomb that the explosion is at the scale of “searing heat and sudden hurricane”, and not in close where everything is melted to glass or crushed to dust.

Some are also very far away but with a good zoom lens.
