Presentation at the 2009 American Society of Criminology meeting in Philadelphia (2 parts)This is a talk I gave at the 2009 annual meeting of the American Society of Criminology in Philadelphia in the session titled “Power Crimes.” Four of us from AE911Truth presented papers at this meeting. The others were James Gourley (attorney with chemical engineering background), Tony Szamboti (mechanical engineer), and Bob Fischer (biochemist).
My Response to Chris Mohr’s rebuttal to Richard Gage on the collapse of World Trade Center Building 7. (The video being discussed was removed from YouTube by the owner.)
Individual Analysis Videos (most recent at the bottom)
South Tower Coming Down
Video segment of the collapse of the South Tower, taken apart frame-by-frame, rectified so the building remains motionless, and reassembled into a movie, with commentary.
Race with Gravity
Video analysis, using Physics Tool Kit software, of the speed of the demolition wave moving down a face of the North Tower in comparison with the rate of freefall through air of heavy material nearby. (Acceleration + Serendipity is a more updated treatment of the same phenomenon.
(Analysis based on the BBC footage which can be seen in full here.)
The Terrorism Scam
This You-Tube video is a commentary piece about the virtual non-existence of a US terrorism threat. Yes, there is such a thing as terrorism, but it is adequately covered under the heading “murder.” Making it a special class of threat is an emotional appeal that induces fear and makes the population willing to give up civil liberties and even violate human rights. In the case of terrorism, the cure is worse than the disease.
North Tower Exploding
This is an narration of a video clip of the North tower which focuses on explosive ejections progressing in waves down the faces of the building. Among other things it is a response to theories that postulate causes for the collapse that ignore the evidence that can be easily seen by anyone in the video footage itself. Observation is the foundation of science.
WTC7 in Freefall–No Longer Controversial
The previous analysis of the freefall acceleration was criticized (legitimately) for using a horizontal calibration measurement for analyzing purely vertical motion. Any distortion or stretching of the video could throw off the measurement. In this new video, the calibration utilizes NIST’s data for the heights of the roofline and the 29th floor to do a vertical calibration. The result is a measurement even closer to idealized freefall: 9.88 m/s^2.
[Another video maker, "skeptic121" who wishes to remain anonymous, has posted a similar measurement using a different video and using a different technique. It contains interesting comparison measurements from other collapses as well.]
WTC7: NIST Finally Admits Freefall (Part I)
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 illuminating video displays the brazenness of the NIST WTC7 coverup. John Gross, one of the lead structural engineers for the NIST investigation, who figures in this video, has established a reputation for lying and evading evidence. (Another example of John Gross’ evasive interaction with questioners on other a different key piece of evidence.)
NIST has removed the video of the press conference from their web site. Here is an un-edited video clip of the parts dealing with the questions from David Chandler and Steven Jones. (Also, here is a transcript of the whole briefing.)
WTC7: NIST Finally Admits Freefall (Part II)
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 in Part III
WTC7: NIST Finally Admits Freefall (Part III)
Part III fully explores the implications of NIST’s admission that freefall occurred and critiques the foundations of their “investigation.” In the end it calls for a new, independent, fully empowered, and open investigation.
[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. I will also use this FAQ as a place of reference for other questions that arise as well.]
Downward Acceleration of the North Tower
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 the weight of the falling section. 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. The complete analysis of the phenomenon illustrated in this video is published in a paper called Destruction of the World Trade Center North Tower and Fundamental Physics, Journal of 9/11 Studies, February 2010.
[I want to acknowledge the work of Graeme MacQueen and Tony Szamboti who have been engaged in similar measurements by other means and have reached similar conclusions.]
South Tower Smoking Guns
This video narrates a collection of diverse phenomena in the debris cloud of the South Tower that point to explosive demolition. Particularly notable is one projectile (which I have not seen discussed previously) that is shooting to the east, then stops, midair, then turns a sharp corner and shoots straight down trailing white smoke. White smoke is characteristic of aluminum oxide which is a byproduct of the thermite reaction.
South Tower Smoking Guns (Follow-up)
After finding the projectile that turns a sharp corner while trailing white smoke (which I have dubbed the “Angle Rocket”) I looked for it in other videos and found it in several. The clearest is from a camera with a very similar perspective to the first, but in this video the trail can be followed to the bottom of the collapse. Here I explore the significance of this find.
South Tower: Exploding Projectile
A close-up view of debris being ejected from the South Tower of the World Trade Center as the 30-floor top section falls to the east shows numerous smoking projectiles that look like comets. Several of them can be seen to explode. One such exploding projectile is followed here. It ejects two fragments, both of which undergo secondary explosions. (Note, the rising fragment to the left of the projectile under consideration appears to be a tumbling object that alternates from black to white to invisible. It passes behind one of the fragments described in the video.)
Cutter Charges in the North Tower of the World Trade Center
Small explosive ejections focused on a corner column of WTC1 (The North Tower of the World Trade Center) are evidence of cutter charges used to cut the corner columns. One of these occurs at the 98th floor at the onset of the demolition of the building. The other occurs lower in the building at the instant the column enters free fall.
Acceleration + Serendipity
This is a study of the overall downward acceleration of WTC1, the North Tower of the World Trade Center. During this investigation it was discovered that the one feature that kept pace with the original acceleration of the roofline was a wave of ejections on the west wall.
High Speed Massive Projectiles from the WTC on 9/11
I have revisited and extended some of my early measurements of high speed massive projectiles from the World Trade Center on 9/11. The results for the three projectiles measured: 56 mi/hr, 45 mi/hr, and 78 mi/hr. I don’t claim this is smoking-gun evidence of explosive demolition all by itself, but it is part of the puzzle and it is more compatible with the explosive demolition hypothesis than simple gravitational collapse.
(On a technical note, if you are looking at the numbers in the three measurements, the third measurement is taken while the video was zoomed in, relative to the calibration frame. The numbers shown have to be scaled down by a factor of 1.701 to give the stated results.)
WTC 7: Sound Evidence for Explosions
There is ample evidence, from both witnesses and recordings, of explosions associated with the destruction of World Trade Center Building 7 (WTC 7). NIST sidestepped investigating explosions and explosives by setting up an artificially high threshold of interest. They swept aside any testimony or recordings of explosions that would not register 130-140 dB one kilometer away. They established this criterion using RDX (one of the loudest explosives) in a scenario that produced a far higher sound level than other possible uses of explosives to bring down the building. Then they turned around and used sound level as the sole criterion for deciding whether the use of explosives was a credible hypothesis. By this maneuver, they sidestepped investigating testimony of explosives or possible evidence of explosive residues. This is just one more instance of fraudulent behavior on the part of the NIST investigation of the World Trade Center disaster.
What a Gravity-Driven Demolition Looks Like
The official story is that the North Tower of the World Trade Center collapsed due to gravity. This has been critiqued in an analysis by Graeme MacQueen and Tony Szamboti, and in a related analysis by David Chandler (both in the Journal of 9/11 Studies). The Balzac-Vitry demolition was a true gravity-driven collapse. The same analysis that was applied to the World Trade Center is here applied to this known demolition, with contrasting results. This analysis supports the conclusions of both papers referred to above: the North Tower of the World Trade Center was not a natural, gravity-driven collapse.
Rockets at the World Trade Center
Some of the debris from the South Tower at the World Trade Center shot downward faster than gravity. This is literal, visible proof of explosive materials painted onto perimeter wall units.
