Could troops survive a nuclear attack without any effects? With the development of the atomic bomb, the military performed tests that put soldiers and animals at ground zero, exposing them to radioactive blasts. See the results in this revealing document.

S01E04 Nuclear Effects

Little was known about adapting the human body to the strenuous laws of physics in the early years of flight. The answers came from subjecting animals and humans to violent impacts, sudden decompressions, extremes of heat, cold, and radiation, and more.

S01E03 Beyond Human Tolerance

Witness all the incredible human testing performed by the military in the 1950s to develop high-altitude escape systems for pilots. See the amazing 14-mile drop of a man through the sound barrier with just a thermal suit and a parachute, and still survive.

S01E02 The Human Rock

The story of G-forces and the human tests that made sudden acceleration and deceleration survivable for Air Force pilots in the 1950s. See humans and crash dummies in rocket-powered sleds reaching the historic 82G impact and other achievements.
