Huck;
Obviously "the PIO" cannot be shown because we don't have any data, nor is "demonstrating that it was PIO", the issue. Nobody can make that judgement from the video. The issue is, the MD11 has a demonstrated propensity for this kind of accident. Why?
I fully realize there are a lot of factors in deriving a set of truth-statements regarding this history. I realize that there exists a lot of economic and political interests which desire that their versions prevail, and most important as a flight crew member (now retired), the matter has a substantial human element for which I have greatest empathy.
The suggested reading on the notion of "APC" is at least interesting but it is a discussion of "APC", not a discussion of the MD11 specifically. I've downloaded the book,
Aviation Safety and Pilot Control: Understanding and Preventing Unfavorable Pilot-Vehicle Interactions (1997) in pdf format, (takes about a minute on high-speed).
