>> reporter: there he was at 128,000 feet standing quite literally on the edge of space, preparing to do what no one had done before, with his mom watching from mission control , 43-year-old felix baumgartner offered a few words most hard to understand.

>> when i'm standing up on the top of the world you become so humble you want to come back alive. you do want to die in front of your parents and girlfriend.
