Compare this to an airline cabin where the air pressure is greater on the 
inside of the cabin than it is on the outside of the cabin.  I'm confused 
on this because if it turns out that the pressure is greater on the 
inside, why is'nt the crew crushed.  On the other hand if there is less 
pressure on the inside, why isn't the hull crushed?
