The “sound barrier” is not a physical barrier, like a wall. You wouldn’t come to a complete stop. It’s just the point at which you’re moving so fast that the air no longer has time to move out of the way, and so it behaves differently.
It would be really rough on your body, to be sure, but not as bad as hitting a magic wall that makes you come to a complete stop.

I watched the excerpts of his video but never really explained why the turning happened for a while then stopped?

How would you control your spin if there’s no air to push against? The ionosphere is so thin, it may as well be hard vacuum. until you made it to some place the air is thick enough to help control your rotation, once you start spinning, you can’t stop.

But why in the first place did he start spinning? The people they talked to were awaiting it and were suprised it didn’t come thru sooner.

Yeah, we’re not a regular, balanced geometric shape. Without a tether or something to help stabilize against, every marginal push or pull (like gravity, or the marginal friction of the ionosphere) will tend to send us tumbling.
