Yes, on a more thorough reading I can see the event was well outside the survival parameters. The suit was still impressive, though at 100,000ft and 560kts EAS! Interesting to note the comparison with the SR71 suit performance, and I see the suit failure may have been aggravated by the open visors (3-46).
I was pleased to see that the crew received worthy praise for their attempts to diagnose the unknown events before the CE.
