Burning a fate point allows you to avoid death if it's feasible. Being naked in space for example would mean death can't be avoided. So falling so far, how did he manage to survive?
Probably the same way real life people who fell from far greater heights did.
The trick lies in not dying from the sudden deceleration.
If it's something unenhanced, real life humans are capable of, I don't require my players to give special explanations when burning fate points. Especially if it's the result of an awesome action and disallowing it would result in an uninteresting death.
