The maximum g-force tolerance for the human body is approximately 9 g's (where 1 g equals 9.8 m/s²), which trained fighter pilots can endure for short durations. In contrast, astronauts aboard the Space Shuttle have experienced several g's during launch, highlighting the importance of acceleration over constant velocity in hypersonic travel. Horizontal g-forces can be tolerated at levels 2 to 3 times higher than vertical g-forces. Understanding these limits is crucial for the development of future hypersonic aircraft capable of rapid global travel.

Mind Bender said:I'm fascinated by hypersonic aircraft. But what is the fastest velocity the human body can withstand? Mach 6, Mach 8? I look forward to the day when people can circle the globe in a matter of minutes. Will this be possible?
If I remember correctly this is true for vertical g-force, for horizontal g-force 2 or 3 times more is survivable.berkeman said:Trained and fit aircraft fighter pilots can withstand 9 times the acceleration of gravity (one "g" = 9.8m/s^2) for brief periods of time.
