astroengine writes "We've all wondered about it. When flying at 30,000ft, you look around the cramped economy class cabin thinking 'I wonder if I'd survive being sucked out of this plane if a hole, say, just opened above my head?' That's probably around the time that you should fasten your seat belt. According to medical experts interviewed by Discovery News in the wake of the Southwest Airlines gaping hole incident, the rapid depressurization, low oxygen levels and freezing cold would render you unconscious very quickly. Assuming you don't get chopped in half as you exit through the hole and hit the tail, you'd be long dead before you hit the ground. Nice."
