Did they figure out the issue with his visor heat? Surely he ain't gonna jump if has a visor that's gonna frost up.

I believe he can ride down with the capsule if needs be. But that's probably just as dangerous.
allready done, Stratos jump successful! http://www.youtube.com/watch?feature=player_embedded&v=yFU774q6eVM
