Free fall at over mach 1.25! I wonder if he experienced the shock wave? Or was the air too thin.

I would think it was too thin or he never would have been able to achieve such speed.
I was watching the airspeed/mach indication and after a few seconds of the highest mach reading his speed started dropping rapidly. It would have been interesting if they had been recording the audio and the boom was evident or not. I know the shock wave would have been dependent on air density.

Notice that when he first bailed there was no wind sound and his suit was not flapping? As he fell into thicker air the sound picked up and the material on his suit began to flap.

My audio was muted! I listened to it several times and if there was a sonic boom it must not have had enough atmosphere to make a sonic boom.

    There was an issue early on with the chat where the messages where the color white, so you couldn't see it. I wasn't sure if I fixed it for only myself or everyone. How does it look?

    I can see it. Everything looks like Microsoft Calibri TTF now, which is good.
