Nuclear Test Film - Operation Upshot-Knothole, 5.2
61 kt · 1953 · Nevada Test Site · 4 Hiroshimas
A second reel of Operation Upshot-Knothole (1953) concentrating on the weapons-effects program: the test houses, automobiles, bomb shelters and instrument arrays built across the Nevada desert and exposed to the blasts.
Aftermath
Footage of frame houses bursting into flame and collapsing under the shock front became the template for the civil-defense films that told Americans they could survive a nuclear war by ducking under furniture.
