That should be enough to reduce the chances of whiplash, and the tears might
not completely boil away before they could get back into a pressurized

Mmmmmmhhhmmmm.

Yeah...but the zero pressure can make your eyes pop out and stuff like that
after a while.

Not before they freeze, and even that will take a while (contrary to popular
belief, while vacuum is extremely cold, without any matter to convey the heat
away, it does take a while to achieve freezing temperatures). There’s not a
lot of air inside the human body, and nearly all of it is found within the
lungs. They can and will rupture if you try to hold your breath in a vacuum,
but not the eyes. The human body is actually more structurally sound than a
Boeing 747, and the only known significant difference between being exposed
to vacuum and being exposed to non-oxygenated air is that water will boil
away at low enough pressure. Either way you die of oxygen-deprivation,
though you end up losing some moisture first in a vacuum.

I see.

Thanks and PLMKWYT about the subject.

I believe I already did. However, if
you want to read real scientific accounts of what would, and what has,
happened in the event of human exposure to vacuum, try
this.
Don’t worry, there’s nothing gruesome or violent, and noone in the factual
accounts was actually harmed. Probably the most famous instance of vacuum
exposure is the one in 2001, where Dave has to clear the gap between his pod
and the airlock sans spacesuit. It should be noted that the book was written
by Arthur C. Clarke, who is not known for filling his books full of
scientifically unsound events. This anime version, however, while not
scientifically improbably (aside from the artificial gravity, which can
currently only be generated by centrifugal force), involves such a level of
split-second timing as to be very unlikely to happen without some sort of
mishap that would prevent the successful rescue, or at least require the ship
to go chasing at least one drifting body. And just what the heck would they
have a rocket-propelled rope for anyways? It’s not like this is the sort of
event that would be part of the standard training retinue.

Who knows where they got that rope? :D
Well, thanks a lot guys.
Cheers (*clink*)
