Scary spin! I guess humans were not meant to fly at Mach 1 above 40,000 ft.
Back around 1960, the US military jumpers who tried it mostly died in the attempt. A drogue chute was used to prevent the high-Gs spinning that would knock them out and then kill them in midair.
I watched this video last week, or whenever it was, when it was released. The clarity is amazing. To me the jump itself is the most mesmerizing. It’s hard to tell what’s happening during the spin. The telephoto view of the spin which was shown live was much scarier from my POV. I couldn’t see how he was going to come out of it, when suddenly he straightened out. I imagine he had to get to thick enough air so that he could manouver they way he was used to. He had a lot of experience!
