| Description |
The effects of air pressure on the human body are studied, with emphasis on the protection which the Earth’s atmosphere affords, by enabling men to breathe, by preventing the body fluids from bubbling away as gas, by cushioning the impact like meteors from outer space, and by removing the lethal threat in ultraviolet and cosmic radiation. Col. Sweeney narrates his pioneer experiments in “explosive decompression,” the sudden loss of cabin air pressure by a puncture from a chance encounter with a meteor in space.
