Algy: my mistake. The initial news reports were not good. "Airbus calls off test early due to injury", "slide collapses" and so on. I was in the middle of spewing pompous blather when you posted the link to your excellent account (which answers a few of my other questions).
heck, even now, the headlines read:
"32 Hurt in Airbus Test Evacuation", "Volunteers Injured in Airbus Test"
If I were boeing, I'd be sending a nice gift to the editors who came up with those headlines.
CD: Thank you for the corrections.
