I seem to recall that the Apollo astronauts were subjected to 8 G's. The Shuttle boosts at about 3 G's. There is an interesting trade-off in that: higher G boosts are more efficient in fuel, so payload is increased. On the other hand, you have to build your payload stronger and brace it better, which is parasitic and a pain to boot. Also, I wouldn't be surprised if it is harder to build engines tat run at the higher boost - and making them multi-shot wuld be even harder. Steve Den Beste
