Armstrong Limit
Armstrong Limit - Wikipedia, the free encyclopedia
Armstrong's Limit, is the altitude that produces an atmospheric pressure so low (0.0618 atmospheres), that water boils at the normal temperature of the human body: 37 °C (98.6 °F). It is named after U.S. Air Force surgeon Harry George Armstrong, who first described it.
The altitude is variously reported as being between 18.9–19.4 km (62,000–63,500 feet or about 11.8 miles)[2]. At or above this point, exposed human fluids will boil without a pressure suit, and no amount of breathable oxygen, delivered by any means, will sustain life for more than a few minutes. A human would, eventually, boil in their own body fluids (a process known as ebullism), though death from asphyxiation would occur first, as the barrier of the skin and control of blood pressure would prevent blood from boiling immediately
did any idiots ever make it back?
