From the introductory material for this talk:

With a clarity that both the layperson and the scientist can understand, David will answer these questions as he challenges the National Institute of Standards and Technology’s (NIST’s) reports on the building collapses on 9/11.

1) What is the official story of what happened to the World Trade Center (WTC) buildings 1, 2, and 7 on 9/11?

2) NIST has had an excellent reputation in the past. Why should we doubt its report on the collapse of the WTC buildings? Was NIST’s report actually fraudulent?

3) Building 7 (WTC 7) fell at absolute free fall for the first 2.5 seconds. What is free fall? How is it measured? Can a building naturally free fall while crushing itself, as the official story claims?

4) The North Tower (WTC 1) fell with uniform downward acceleration (but less than free fall). What are the implications in this case?

5) What do the free fall of WTC 7 and the near free fall of the Twin Towers tell us about the nature of the 9/11 event? What are the larger implications for today?Q and A: Please come with your questions. Below in David’s bio are some websites for you to study prior to coming, if you would like.

David maintains a website in collaboration with several other scientific researchers at http://911speakout.org.

BIO: David S. Chandler has a BS in physics from Harvey Mudd College and an MS in mathematics from California Polytechnic University. He has taught physics, mathematics, and astronomy at the high school and college levels since 1972. He is now retired and living in Denver, Colorado.

Since about 2007 he has been active as a researcher with what he calls the “science wing” of the 9/11 Truth Movement. He is currently the Coordinator of Scientists for 9/11 Truth (http://scientistsfor911truth.com), and worked for several years with Architects and Engineers for 9/11 Truth (http://ae911truth.org).

David has authored and co-authored a number of scientific papers on the events of 9/11 including Destruction of the World Trade Center North Tower and Fundamental Physics (http://journalof911studies.com/volume/2010/ChandlerDownwardAccelerationOfWTC1.pdf). He has written a six-part serial essay posted at Medium.com, titled Free Fall (https://medium.com/@davidchandler_61838/free-fall-131a94a1be7e), which is the basis for this talk.

[This is a reposting of this video which was taken down from the original site, originally posted in August 2008 just after the release of the final draft of the NIST WTC7 Report, prior to the final version which was altered to admit a 2.25 second period of freefall.]
This video tracks the motion of the NW corner of Building 7 of the World Trade Center on 9/11 2001. The building was in freefall for a period of ~2.5 seconds. This means it was falling through itself for over 100 feet with zero resistance, an impossibility in any natural scenario. This period of freefall is solid evidence that explosives had to be used to bring the building down. In the final draft for public comment (August 2008) NIST denied that WTC7 fell at freefall. In the final report in Nov 2008 they reversed themselves and admitted freefall, but denied its obvious significance.

[The WTC7 series has elicited a number of questions from people unclear on the details of how I did the measurements, compared to how NIST did them and how the representatives of NIST described their measurements. I have therefore created a WTC7 Measurement FAQ page: http://www.911speakout.org/WTC7-Measurement-FAQ.pdf . I will also use this FAQ as a place of reference for other questions that arise as well.]

The roofline of WTC1 (The North Tower) begins dropping with sudden onset and accelerates uniformly downward at about 64% of the acceleration of gravity (g) until it disappears into the dust. This means it is meeting resistance equal to about 36% of its weight. The implication of this, however, is that the force it is exerting on the lower section of the building is also only 36% of its weight. This is much less than the force it would exert if it were at rest. The acceleration data thus prove that the falling top section of the building cannot be responsible for the destruction of the lower section of the building. A complete analysis has been published in the article entitled "Destruction of the World Trade Center North Tower and Fundamental Physics," Journal of 9/11 Studies, Vol 28, Feb 2010: http://journalof911studies.com/volume/2010/ChandlerDownwardAccelerationOfWTC1.pdf (Some calculus and basic physics required.)

This is a narration of a video clip of the North Tower of the World Trade Center which focuses on explosive ejections progressing in waves down the faces of the building under the canopy of falling debris. Observation is the foundation of science.

[This is being reposted becuse the previous version was corrupted (hacked?). Please update any links or embeds.]

In its draft report, released in August 2008, NIST attempted to cover up evidence that WTC7 fell at freefall, but the coverup was transparent. In its final report, released in November 2008, NIST finally acknowledged freefall, but couched it in a bizarre framework that continues to deny its clear significance. This video displays the brazenness of the NIST WTC7 coverup.

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.
...More to come soon in Part III.

Part III of this series fully explores the implications of NIST's admission that WTC7 entered actual freefall and critiques the foundations of their "investigation." In the end it calls for a new, independent, fully empowered, and open investigation.
