Wasn't it the 777 evacuation test where somebody was rendered permanently
paralyzed? A hell of a way to earn $500.

An emergency evac, real or drill, is a dangerous procedure, and usually
results in more than a few injuries, some serious. In the real world,
ordering an emergency evacuation of a large airplane is a decision taken
very carefully. The question is which course of action will result in fewer
injuries. When you get to the point where an evac is one of your top
alternatives, some people are going to get hurt, either way.
