I still think Dr Judy Wood’s research on that point is more convincing. She went backwards and over that issue with a fine toothed comb. And her PhD was smack in the middle of the physics of the materials.
Dr. Wood's area of engineering expertise is BIO-mechanics, not steel or building mechanics. They are two completely different areas of study and really do not intersect. She is talking about something outside of her actual field of expertise... or really on the fringes of her field, challenging people whose life work is in that field. Sorry, I do not give her opinions much weight.
She's a proponent of the non-reproducible "Hutchison Effect." While it is entirely possible that there is something to what Hutchison tapped into (I am a proponent of the Plasma/Electric Universe), he ruined himself and others by faking some of his evidence. That fakery redounds onto Dr. Wood's credibility since she has never admitted his culpability in that fakery, even when Hutchison admitted it. It is particularly egregious because much of her claims about the WTC failure is based on the use of the Hutchison Effect.
Extraordinary claims require extraordinary proof. She fails. It is why Wood is a former assistant Professor, and has so few peer-reviewed papers to her name, all from 2004 or before.
She is the very definition of a tin-foil hat brigade member, Jocko, and in my opinion could be their poster child.
