IF you’re of a grisly disposition, and want to find out what would happen to
an astronaut forced to jump ship into the hard vacuum, there is a description
at: http://www.jsc.nasa.gov/sa/sd/intro/vacuum.html. The information is drawn
from experiments in the mid-60s, in which some very unfortunate chimpanzees were
exposed to decompression. Thankfully there are no links to the original
papers.
