Aren't the 10,000 G the lateral force at max rotational speed? I don't think that the transition from vacuum to sea-level pressured air would result in a 10,000

Aren't the 10,000 G the lateral force at max rotational speed? I don't think that the transition from vacuum to sea-level pressured air would result in a 10,000 G de-acceleration. But it really must be a non-neglectible impact-like effect.
