The issue with the U2 pilots was that they were wearing uninflated suits in a cabin pressure way too low.

Okay... you're an insider then? Can you please amplify?

This isn't a great topic to speculate about.

Here are the facts as I know them:

The suit is backup for cabin pressure failure, only.

Nominal cabin pressure is 29K.

Pilot is on 100% ox (from two hours before takeoff).

This isn't a hypoxia problem.

The inference that can be drawn is that neurological DCS is more insidious than most realize. That was the point of linking the article.
