Not relevant, considering that it was not physically possible to bring those buildings down with airplanes. Not to mention Bldg 7. (You didn't see this on TV? Oh, wait; you'll have to consult a physicist on this one. Yeah... too much trouble, I know.)
Story
Ignore the carnival barkers.
----------
I studied physics when I was at Clarkson University. I did great in it, but not in the courses I did not attend. So I was not invited to return.
But anyhow, it was a waste of time. Little did I know that understanding the universe wouldn't come from the inside of a linear accelerator...but from the inside of a pot pipe.
But that doesn't change the applicability of Newtonian Physics here. I know the New York Times doesn't think so, but then they're not economically relevant, either.
