Just how powerful was the shock wave? These are the tests that provided the answers that today are the core of America's nuclear weapons knowledge. Formerly classified material documents Operation Tumbler Snapper, which detonated small yield atomic weapons to determine their effectiveness on troops, animals and buildings. At Ground Zero (74 Min) - Full photographic coverage of the only tests ever conducted of the effects of a nuclear bomb on a typical American community.
