says maybe 24 g if you were totally immersed and properly oriented (sustained) but to go any higher you would need to be breathing liquid.

Good luck

Answer 4

This roller coaster pulls 6.5 G's which is the most made in the world of roller coasters.

You can pull more to even a point where you pass out.  But in the eyes of injury you will not be injured whatsoever as long as you properly wear belts, clips, overheads or whatever they use to hold you in.  That's what these things are designed for.

Answer 5

It varies by person. In general, women or smaller people deal with Gs better. Numbers from NASA and the airforce seem to indicate 13 positive (not sustained) or 9 positive sustained for about 30 seconds without a suit and without passing out. Negative Gs are worse. If you have more than 2-3 sustained, "redout" and pain will result. Yes the amount sustainable by pilots can be increased by behaviour and G-suits. They are trained to squeeze stomach muscles and other muscles to keep blood in their heads. G-suits help by using compressed air to squeeze the legs and lower body of a pilot to keep blood in the head. G-suits don't help for negative Gs and none of this is particularly comfortable.

Nothing from a rollar coaster is going to harm you.
