BYU Physics professor Steven Jones has stated that the government agency tasked with examining the collapse of the World Trade Centers did NOT investigate any anomalies in the collapse of the buildings, failing to even examine any evidence regarding the buildings’ impossible near free-fall speeds and symmetrical collapses, apparent demolition squibs, the fact that the buildings turned to dust in mid-air, the presence of molten metal in the basement areas in large pools in all of the buildings, or the unexplained straightening out of the upper 34 floors of the South Tower after they had precipitously leaned over and started toppling like a tree.

I just ran across an article from a respected civil engineering trade journal which backs up Professor Jones' claim that the government did not really examine the conditions immediately prior to collapse or the collapses themselves. Specifically, the article from the journal of the 180-year old UK Institution of Civil Engineers states:

"World Trade Center disaster investigators are refusing to show computer visualizations of the collapse of the Twin Towers despite calls from leading structural and fire engineers".
...
In other words, the U.S. structural engineer is saying that even the non-visual computer models which NIST used to examine why the trade centers collapsed are faulty.
