The 4th and final model was done not to assess the effect of fire but to assess the effect of removing Column 79. What that model showed was the EPH roofline would kink just like it did, the EPH would then collapse - which it did, and a progression of failures would run through the load transfer region causing the global collapse of the structure from east to west just as we saw on 9/11. That the failure of Col. 79 would cause progressive global collapse was not expected and to me at least is the most significant and important part of the NIST investigation (and most overlooked by CT's). This was if you will, a design flaw of the structure but one that would have never revealed itself except under extraordinary circumstances such as those on 9/11.
In other words, NIST concocted a model, eliminating any inconvenient data, concocting whatever data was needed and changing other data, in order to try to create a model that might cause their model to
progressively collapse, based on their preconceived idea that removing column 79 would come as close as possible to mimic a fire induced collapse and called it a "probable collapse scenario", which had nothing to do with NIST's first objective. Then NIST created an intricately detailed report, using all that carefully selected data, including their counterfeit structural diagrams, and published a report that they
KNEW most people would determine is the exact scenario that they would conclude happened. They also
KNEW most people would never read the report, much less go over it with a fine tooth comb. But they
KNEW as long as government sanctioned that report as the
OFFICIAL NARRATIVE on the collapse of WTC7, they would go along with it because it comes from authority. And they
KNEW most people fall for the belief that authority = truth, rather than truth = authority. And just to make sure to cover all their bases, NIST withheld as much data as they could, even under FOIA requests, as long as they cited that releasing such data would
ENDANGER PUBLIC SAFETY. And just to make sure all this was kept in the dark as much as possible, government got their puppet media to make sure never to publish anything about WTC7 (minus a couple of leaks) so that as many people as possible would remain completely ignorant about the collapse of WTC7. But as we can see recently with C-SPAN, even this tactic is not working.
The problem with all that deliberate OBFUSCATION is that it didn't work for experts and other educated intellectuals who know better, but these are in the minority and since they're not government, they're not accepted as authority by most people. And as long as the MSM and government labels these people as "conspiracy theorists", "kooks" and the like or marginalizes them as a few disgruntled malcontents, most people just accept that and will not do the research. But the problem with that is that government and the MSM have an awful track record and many people no longer accept what they're fed by the propagandists and turn to those they see as much more credible. And that's why 9/11 will NEVER GO AWAY and the number of people who want real answers is GROWING DAILY. Some of the evidence for that is shown by the EVER INCREASING number of signatories of experts at AE911, many of whom are first learning about WTC7 as well as the 100,000 plus petitioners (so far) in NYC who demand a REAL INVESTIGATION into the collapse of WTC7.
