Am I the only one who ever thinks about countering g-forces by allowing a pilot to be submersed in liquid instead with neutral boyancy. This would completely eliminate passing out from g-forces at any acceleration factor.

Though of course it would be complicated so I understand why it isnt done. You would need a complicated system to maintain pressure in the tank so it wont fluctuate quickly. But since g-forces are usually transient if done correctly decompression might not be a big issue
