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. Blake Freeburg
