"Squeeze the butt, squeeze the legs, breathe..."
Those were the somewhat comforting words being yelled at a man who was undergoing 9G centrifuge training. Impressive.
High-G training is usually undertaken by pilots or astronauts in order to prevent them from losing consciousness when they encounter high G-forces that can cause the blood to flow away from the brain.
The trainee appeared to fly through the test, despite being subjected to astoundingly high G-forces that could have caused him to black out at any point.
In a video posted by YouTuber davidthefritz, the man appears to successfully pass his test. His friend later posted the video on Reddit, where the young trainee received high praise from Redditors.
G-force is the force exerted by gravity when a body accelerates and a 9G-force would be at the higher end of the range forces a pilot usually experiences while flying a jet.
Two years ago, a Red Arrows Flight Lieutenant almost lost consciousness and crashed while experiencing a 6.3 G-force.
