MOST of our current chemical rockets can do this, so building an engine or
vehicle that can withstand 9 g's isn't impossible, as for special designs,
most modern homebuilt kit planes are designed for a maximum loading of 9
g's. There isn't anything terribly special about using this as a maximum
As for continuous acceleration, for the high end category I think 10 m/sec
(1 g) should be the absolute minimum. BTW, before someone jumps my shorthand
version, I am purposely not writing the ^2, its a danged nuisance...I assume
that is why you wrote the m/ss?
