“The human body, for all its extraordinary capabilities, is just not made to take 6, 8 or 12 times the normal force of gravity. And its responses to this assault, from impaired vision to loss of consciousness, can prove fatal if they occur in the air.”

All About G Forces
“Before the advent of airplanes, which could accelerate the human body like nothing before, people rarely experienced G forces. So-called gravity forces first became a concern during World War I, when pilots began mysteriously losing consciousness during dogfights. As early as 1919, a doctor wrote up this strange phenomenon for the literature, calling it ‘fainting in the air.’”

Maxed out: How many gs can you pull?
“Our tolerance of g-forces depends not only on the magnitude and duration of the acceleration or deceleration but also on the orientation of our body. We are most vulnerable to a force acting towards the feet, because this sends blood away from the brain. Five to 10 seconds at 4 to 5 g vertically typically leads to tunnel vision and then loss of consciousness.”
