You would lose conciousness almost instantly. The air would be sucked from your lungs. Pain?
It's hard to feel pain when you're unconcious. So, no. As long as you were returned to a pressurized environment rather soon you could easily recover.
It's not like in the movies. People have been accidentally exposed to vacuum during pressure suit tests. One famous example happened during testing of the Apollo spacesuits.
I forget the fellow's name but he is interviewed in that documentary "Moon Machines". He said that just before he blacked out he could feel the saliva boiling off his tongue. They got in to him and repressurized the area within about 30 seconds.
By the time the rescuers got in to him he had already regained conciousness. He walked out of there himself.
It is possible to survive exposure in space for around 90 seconds. In fact, an astronaut working on the space station had a leak in his suit and suffered some of the immediate effects before rescue. Of course a leak is not as bad as finding yourself in space with no spacesuit on at all - it's highly unlikely you would be protected enough, or survive long enough, to be saved.
It is likely you would lose consciousness within a minute. It would be pretty nasty. People who have suffered this report intense cold with ice crystals quickly forming on the skin, but with the liquid in their nose, eyes and mouth boiling due to the pressure difference.
The air would be forced from your lungs even if you try to hold your breath. Having said that, it's relatively quick I suppose. Quicker than falling off of a skyscraper, or burning to death.
Best not to try it, though.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
