The conclusion of NIST's 10,000 page report that took seven years to produce claims fires, coupled with "thermal expansion" and "unusual truss design" caused core column 79 to fail, leading to a complete "progressive collapse".
The absolute impossibility mentioned in the headline above is evident in their computer simulation of the physical copllapse as initiated by core column 79. In reviewing the individual screenshots, and when seen in the non-NIST animation of their screenshots, it becomes apparent that the collapse they postulate is totally different from all videos of the actual collapse.
In their simulation, the East side of WTC7, where column 79 was located, fell completely down taking over 25% of the building to the ground, while the balance of the building was as yet unaffected.
In reality, every video of this collapse (seen from the West, North and East) showed the building maintaining total integrity of the complete roof line and all four sides as well. It collapsed in a synchronous manner, as if it had been constructed on a massive elevator and someone had pressed the "down" button.
WTC7: NIST Finally Admits Freefall (Part III) is now posted on YouTube. This concluding segment explores the implications of NIST's concession (to easily observed reality) that freefall occurred.
This is not the "Part II" I had originally envisioned. That will have to wait for Part III. In following up on the erroneous measurement described by John Gross in Part I, I decided to look more carefully at the measurement and find the video frame NIST claims marks the beginning of the collapse. What I found is that there is no motion of the roofline for at least 20-30 video frames after the point identified by John Gross. In other words, the measurement is a complete fabrication with the goal of producing a "measurement" to agree with the result predicted by NIST's collapse model. This result is sufficiently significant to merit its own video.

NIST has now officially accepted that WTC7 came down with the acceleration of gravity, but they still couch it as a phase in a 5.4 second interval they claim matches the 5.4 seconds required for their model to collapse 18 floors. The starting point of their 5.4 second interval is totally arbitrary. This new video highlights the August 26 technical briefing and allows Sunder and Gross to shoot holes in their own feet. Part II, which is planned to come out in a week or two, will go into detail about the implications of freefall. A list of bullet points has been compiled on that topic already, but if anyone has a special take on it that they would like to feed into the mix, please contact me at firstname.lastname@example.org.
The National Institute of Standards and Technology (NIST) today released its final report on the Sept. 11, 2001, collapse of the 47-story World Trade Center building 7 (WTC 7) in New York City. The final report is strengthened by clarifications and supplemental text suggested by organizations and individuals worldwide in response to the draft WTC 7 report, released for public comment on Aug. 21, but the revisions did not alter the investigation team’s major findings and recommendations, which include identification of fire as the primary cause for the building’s failure.
The extensive three-year scientific and technical building and fire safety investigation found that the fires on multiple floors in WTC 7, which were uncontrolled but otherwise similar to fires experienced in other tall buildings, caused an extraordinary event. Heating of floor beams and girders caused a critical support column to fail, initiating a fire-induced progressive collapse that brought the building down.
NIST left out key words in a statement about shear studs so they could falsely claim that there were no studs on the key girder between columns 79 and 44.
This is critical to their collapse theory.

Most of the beams and girders were made composite with the slabs through the use of shear studs. Typically, the shear studs were 0.75 in. in diameter by 5 in. long, spaced 1 ft to 2 ft on center. Studs were not indicated on the design drawings for many of the core girders.

The Council on Tall Buildings and Urban Habitat (CTBUH) has published comments on the NIST WTC 7 Report. The CTBUH questions critical points of the NIST WTC 7 collapse theory and also highlights problems with the writing NIST report itself.
The CTBUH criticisms focus on two technical issues The conjectured failure of shear studs and bolts on the supposedly critical Column 79:
Several conclusions drawn in the NIST report on the contribution of structural
components in failure initiation are unexpected and have raised concerns
within the Council. These conclusions involve the role of both shear studs and
local global buckling of the floor beams in failure initiation. The Council
believes that the local connection performance was a significant part of the
global failure and would like to have seen a more explicit analysis of the
connection failure. (See also comment on Chapters 11-13.)

I emailed the following comments to NIST today, well before the deadline for submitting comments. I utilized Kevin Ryan's recent critique of NIST's draft report. Gregg Roberts gave useful feedback on the text and "Americanized" the language.

Here are my comments on the long-awaited draft for public comment of NIST's report on WTC 7, issued by NIST on August 21st, 2008.

AE911Truth will soon publish its response to NIST's final report on WTC7. In the meantime, this graphic illustrates that NIST's analysis is NOT consistent with photographic and video evidence. A higher resolution PDF may be found here: http://ae911truth.org/downloads/WTC_fire_sim_comparison_080912c.pdf. Please forward this blog and document link to anyone you think can help spread the truth.

Shyam Sunder describes in the NIST technical briefing and the slide show/document titled;
NIST Response to the World Trade Center Disaster Federal Building and Fire Safety Investigation of the World Trade Center Disaster August 26, 2008
states on page 32: “Forces from thermal expansion failed the connection at Column 79, then pushed the girder off the seat.” [to the west]
In NCSTAR 1-9 Vol.1 page 353 [397 on pg counter] it says:
“Axial compression then increased in the floor beams, and at a beam temperature of 436 °C, the northmost beam began to buckle laterally. Buckling of other floor beams followed as shown in Figure 8–27 (a), leading to collapse of the floor system, and rocking of the girder off its seat at Column 79 as shown in Figure 8–27 [to the east]
Dylan Avery posed the question "Who writes this stuff?"
I can't say for sure but the evidence seems to point to one of the founding fathers.

Comments on the Draft Report NIST NCSTAR 1-9: “Structural Fire Response and Probable Collapse Sequence of World Trade Center Building 7”, issued by NIST August 21st, 2008
(Revised and Extended Version of Comments Issued September 11th 2008)
By F. R. Greening
A preliminary (draft) version of NIST’s final report on the collapse of WTC 7 was issued on August 21st 2008 together with a call by NIST’s Investigation Team for the submission of comments on the Draft Report from interested parties within the general public. First I wish to thank NIST for producing such a detailed technical report on the collapse of WTC 7 and secondly, I applaud NIST for allowing researchers from around the world to offer technical feedback that hopefully will be duly considered by NIST before a final version of the report is issued.
Perhaps we should invite David Scott, chairman of CTBUH, to a live open debate. He says he has examined the truth movement's claims and finds in our movement "no credibility whatsoever."
"I believe that the NIST report is a responsible attempt to find the cause of the failure, however there are many questions that are not answered in any detail and several of these questions are already on the discussion forum. I think that with a responsible dialog and debate that the NIST report can be much better and clearer than it is in the current form.
