you know, someone one day is gonna test that out the hard way. begs the question. do we explode when subjected to hard vacuum?
or do we just be unable to draw the next breath?

I still say someone should have spaced a lab-rat just to find this out. I mean, we kill enough of them down here, a 100% terminal outcome isn't unusual for them so why not?

They did use chimps. They didn't explode..

In my long, strange, and morbid curiosity I have wondered just what the airspeed would be at the point of greatest constriction between a standard atmosphere and a hard vacuum. I seem to recall it calculated as being about mach one, with considerably slower speed to either side of the constriction, depending on the volume available in the area near it. Temperature, too -- could one expect high heating as the air compresses at constriction? Obviously temperture drops in the extreme after exit from constriction.
