the articles i've read said from CNN
& other sites confirm:
He experienced one hitch during his fall about three minutes in, reporting, "My visor is fogging up." But more problematic was when he began to veer into a "flat spin" -- which, if it continued, could send blood rushing to his head and left him out of control.
He also says he felt like he was almost in trouble & considered pressing the button for the chute, but realized he had enough control to keep the spin from taking over & that is how he broke the sound barrier
I've been geeking out on this shit all day. I'm sure it's a bigger deal to some more than others, but this absolutely blew my mind. he's a fucking legend in my eyes
other cool quotes:
What he said before he jumped:
"Sometimes you have to go really high to see how small you are"
On breaking the Sound barrier:
" I didn't feel a sonic boom because I was so busy just trying to stabilize myself," Baumgartner said in a statement after landing, adding that he went into a tough spin at the jump's beginning. "It was really a lot harder than I thought it was going to be."
