Just a small question:

How do they fill up the big tank attached to the space shuttle?  More          
specifically, the tank is at ~273K and the hydrogen (liquid) is at <20K,
so how much of it boils off, do they reclaim any of it, and do they precool
the tank with nitrogen ?          

Just wondering after filling a few dewers with liquid nitro.
