When Felix Baumgartner performed the edge of space jump, it's now been calculated he topped out at Mach 1.25 over 825 MPH.

Did he really exceed the speed of sound at any given time (i.e. was there a sonic boom), or was his top speed in feet per second faster than the speed of sound at sea level (where he wasn't)?

The ground videos that have been posted/released suggest there was a sonic boom heard on the ground, albeit a quiet one. I've viewed several of them, and heard something that does distinctly sound like the crack of a sonic boom. The thing that makes it difficult for most observers is that with a human there is no double boom like there is with an airplane as the entire body is supersonic at the same time, there is no aft shockwave developed, even though his feet are a foot or so aft of the rest of his body, they are inside the shadow created by his body.
