9/11
does not go away. It is with us on a daily basis. It has been the emotional
rationale for a long list of radical changes in US policy, many of which continue with us even under the Obama administration:
a supposed "War
on Terrorism"
actual wars in
Iraq and Afghanistan
possible future
wars against a supposed "axis of evil"
condoning torture
and indefinite detention without any kind of due process
scuttling the
Geneva conventions
the sacrifice
of civil liberties at home
If 9/11 "changed
everything," as George W. Bush has said, then it is extremely important
that we "get it right." What really happened that day? The
administration made a rush to judgment, immediately destroyed much
of the evidence, stamped much of the remaining evidence "Secret,"
and implied that critics were "with the terrorists."
If all you know is what you have read in the papers or seen on the TV
News, you are not fully informed, and you are quite possibly misinformed.
We believe you have also been intentionally DIS-informed.
A "9/11 Truth
Movement," inspired initially by families of 9/11 victims, has
amassed a significant amount of research that casts doubt on the official
story line, but many people have never heard this or thought through
the implications. The Bush administration and the compliant media want
this issue to go away, so any attempt to discuss or speak out on this
issue is dismissed as a "conspiracy theory." But keep in mind
that even the official story of 9/11 is a rather bizarre "conspiracy
theory."
Loose Change, Final Cut (also available here)
This is a FAR better video than any of the earlier versions.
The earlier versions were filled with dubious speculation. In this one the film
makers have cleaned up their act. This is an excellent presentation of the issues.
9/11: Total Proof That Bombs Were Planted In The Buildings!
A collection of eyewittness evidence of multiple explosions and "secondary devices"
planted
in the building and exploding over an extended period of time. (I could do without
the dramatic background music, but the eyewittness testimony speaks for itself.)
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.
High Speed Ejection from WTC1 Video analysis, using Physics Tool Kit software, of the horizontal speed
of ejecta from the North Tower. Result: ~73 mph.
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.
(Analysis based on the BBC footage which can be seen in full here.)
Faster than Gravity(Removed) I removed this video because when I did additional runs at different resolutions, I always got extreme accelerations, but not the same amounts in the same places. This made me skeptical of the procedure. Finding accelerations from position data involves double
numerical differentiation, a process that can amplify "noise" in the data. The
raw data in this
analysis is the inherently noisy positional measurement of cloudy
material, and the conclusions were based on the short term variations in the acceleration.
This raises the likelihood
that the extreme accelerations are artifacts. The WTC7 measurements (above) do not suffer the same defect because (1) they are measuring
the motion of a more definite point of solid material, and (2) the conclusions are based on
long term average acceleration.

The Terrorism Scam
This You-Tube video is a commentary piece about
the
virtual non-existence of a US terrorism threat.
High Speed Ejection from WTC1--Further Analysis Further analysis of the data in the original video of this name reveals the location in WTC1 where the ejected object originated: about the 82nd floor. Under even the most liberal assumptions, the building was falling at that point at only half the speed of ejection of the object that is being tracked.
Freefall Acceleration of WTC7
Video analysis, using Physics Tool Kit software, of the uniformly
accelerated
collapse of Building 7 of the World Trade Center
from a distant vantage
point to the NW. (This replaces two earlier
videos of a similar nature.)
This revision is based on a higher resolution
copy of the
video. The inescapable
conclusion that the building underwent demolition is discussed.
(These are more recent and generally of higher quality, both in terms of substance and production value. They benefit from the services of an excellent video archivist and peer review within the AE911Truth team for content. The most recent additions are at the bottom.)
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.
(This video clip was produced for AE911Truth and
posted on their YouTube channel.)
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.
(This video clip was produced for AE911Truth and
posted on their YouTube channel.)
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.)
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 soon 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.
[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.
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.)
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).
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.
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.
