Not totally sure. However, if fuel is chilled to that extent I know it has a tendance of waxing. Fuel is going to become more viscous and therefore less able to flow at low temperatures. In other words if you've frozen your fuel at -47 you are going gliding.
Chances of the fuel thawing out before you hit the ground?
Not much I'd say.
You would need to ask a scientist if you could use it again I don't know any pilots that have found out for real.
