Building 1

Explosive Connections: Initial draft release.

This is only the initial draft release and not all inclusive. I fully expect additions and corrections which I will periodically revise as new and better information surfaces.

David Chandler Updates: 2 new videos and a video interview

1. I have completed a video showing the analysis of the Balzac-Vitry controlled demolition that used hydrolics rather than explosives to initiate a total demolition. This analysis shows deceleration upon collision, as predicted in the paper, "The Missing Jolt: A Simple Refutation of the NIST-Bazant Collapse Hypothesis," by Graeme MacQueen and Tony Szamboti. It also illustrates the symmetry of destruction, contrary to the "crush down" followed by "crush up" scenario propounded by Zdenek Bazant. http://www.youtube.com/watch?v=NiHeCjZlkr8

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 the leading wave of ejections on the west wall.

The Preciseness of AA11 impact

Atta, the wizzard

AA11 impact orientation

The axis (nose) of A11 impacted the exact center of the north wall with some 1m accuracy. The impact speed was 220m/s, the downward angle was approximately 4°, while the lateral angle was less than 3°.

This analysis is based on the visible north face damage and video evidence.

The first picture reflects the upward wing flexing.

[This is an updated version of the video to correct some errors in the characterization of the corner columns and to generally improve the information content. Rather than simply delete the old YouTube video I've added a link to go from it to the new one. This should cover those who have already embedded or linked to the old version. Sorry for the hassle, and thank you members of the AE911Truth team who caught the error. -- DSC]

Aircraft Parts and the Precautionary Principle - © 2006

Impossible to Prove a Falsehood True:
Aircraft Parts as a Clue to their Identity

by George Nelson
Colonel, USAF (ret.)
http://www.physics911.net/georgenelson

The precautionary principle is based on the fact it is impossible to prove a false claim. Failure to prove a claim does not automatically make it false, but caution is called for, especially in the case of a world-changing event like the alleged terror attacks of September 11, 2001. The Bush administration has provided no public evidence to support its claim that the terror attacks were the work of Muslim extremists or even that the aircraft that struck their respective targets on September 11 were as advertised. As I will show below, it would be a simple matter to confirm that they were - if they were. Until such proof is forthcoming, the opposite claim must be kept in mind as a precaution against rushing to judgment: the 911 hijackings were part of a black operation carried out with the cooperation of elements in our government.

David Chandler responds to Frank Greening

Greening vs. Chandler and Newton’s Laws:

The occasion for Frank Greening’s letter is correspondence with several physicists, chemists,
and engineers discussing arguments I made in a video posted on the Architects and Engineers
for 9/11 Truth YouTube page:

This is my response to his letter.

FG:
Chandler concludes that the block was subject to a net force of 0.64M(upper)g. Prior to the
collapse of WTC 1, the lower portion of the building was perfectly capable of holding up the

Downward Acceleration of the North Tower

http://www.youtube.com/watch?v=xG2y50Wyys4

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.

Thermite,inward bowing and the 105th floor.(a new theory)

We all belive ,in controlled demolition of Twin Towers,but do we have a good image about the actual method,which was used to bring them down?And do we have a convincing answer to the inward bowing?I'll show you that we have a very good,convincing answer.

Let me start with this video:

High resolution release of new World Trade Center collapse videos

An anonymous source has released high resolution DVD mpg2 footage of the North Tower & Building 7 collapse clips, reported here on November 1st, 2008: http://www.911blogger.com/node/18358 Also the source has allowed the release of video of the South Tower, and made all 3 available in high quality downloadable DVD file mpg's. These files are cut from source recording DVD VOB files so there is no quality loss, however the sound has been removed, and the video is edited. The source wishes to remain anonymous at this point. View all 3 clips here:

Rotary hears from 9/11 survivor

http://ourtribune.com/article.php?id=3265

Activism idea; join your local Rotary Club, Toastmasters, etc. and give 9/11 Truth speeches.

Article oddities:

"Billy Forney was on the 85th floor of One World Trade Center on Sept. 11 when the first plane struck, with a force that swayed the tower. “At 8:48, in an instant, there was this immediate explosion ... white smoke whipping in and out,” said Forney to Rotarians and guests at last week’s Rotary Club of Humble Intercontinental luncheon."

> 9/11 Commission Report says WTC 1 was struck at 8:46a. This guy is specific about 8:48a; is he mistaken? Paper misquote? What did he say prior to this quote; was he referring to a separate explosion?

"Forney said that at about the 73rd floor, people were running back up, toward his group and the others making their way down."

> More evidence of illegally locked fire escape exits? http://www.mjbarkl.com/locked.htm

"At about the 65th floor, they saw a film of smoke on the ceiling, but they did not know the building was burning."

ESPECIALLY NOTE the very bright flash that appears just before impact. What was that?

The Explosion Few Noticed

The Explosion Few Noticed
Controlled Demolition is Visually Obvious
November 2007

There have been an increasing number of eye witness reports of explosions within the World Trade Center buildings on September 11th 2001. Most notably William Rodriguez has spoken publicly of explosions in the sub-basements of the towers before any aircraft struck them (1). Many police and firefighters have reported explosions as the towers came down (2). Not to mention all the video taped 'regular people' speaking of explosions. So for what it's worth, I will highlight an explosion that is visually obvious but few have focused on.

The collapse of the North Tower (WTC1) happened after the South Tower's implosion. It was a little different than the first tower to go down. The difference was that it started with a very strong, visually obvious explosion.

The Basement Explosions- an Explanation

Folks, it took more than 3 researchers several months to create this study, and it was only possible with the released blueprints. The stories about explosions in the basement and other floors of the North Tower (WTC1) were not new.

The official explanation was kerosine exploding down the elevator shafts.
To this day we wondered what really happened there, what was the real cause, what was the intention of this explosions.

This study set the record straight. There is no possible way that jet fuel or kerosine could be cause for that explosions- it was technically impossible, indeed, when you look at what floors were harmed and what was installed there, a totally new explanation comes in sight.

Go and look for yourself. I've studied the work some time and found no mistake.
In fact, there are several other researchers here in Germany who confirmed the study in total independently, without the knowing of the study itself, only with the keywords and the blueprints in mind.

Here it is:
