Engineer questioning 9/11

Official explanation defies basic laws of physics


ENGLEWOOD — Like most Americans, Jonathan Cole was shocked by the destruction of the World Trade Center towers on Sept. 11, 2001.
And like most Americans, Cole, an engineer and president of Giffels Webster Engineering, initially accepted official explanations for the towers’ destruction, but no longer.
The science doesn’t work, according to Cole, who has produced a series of simple experiments and videos that call into question the National Institute of Standards and Technology’s and other official findings on the disaster.
In late 2007, Cole began questioning all he heard when he was a sent a video of the collapse of World Trade Center Building 7. The video shows the building collapsing down on itself, much like the twin towers; however, WTC 7 wasn’t struck by an aircraft.

Computer animated collapse

Does this give anyone any ideas?

The area under the impact seems incredibly resistant to collapse, unlike WTC 1 & 2 ; (would've liked to see the ball hit higher up)

Someone contact these guys and get them to do a simulation of the WTC'ers!

(SOTT) – Any theory that does not match experiment is wrong. It doesn’t matter what the computer models predict, how much funding is behind it, what the experts say, or what everyone “thinks”. Nothing can fool the laws of physics.

Kevin Ryan: Top 10 Connections Between NIST and Nanothermite

Top 10 Connections Between NIST and Nanothermite
Posted by srsean1968 on October 22, 2009

The National Institute of Standards and Technology (NIST) has had considerable difficulty determining a politically correct sequence of events for the unprecedented destruction of three World Trade Center (WTC) buildings on 9/11. But despite a number of variations in NIST’s story, it never considered explosives or pyrotechnic materials in any of its hypotheses. This omission is at odds with several other striking facts; first, the requirement of the national standard for fire investigation (NFPA 921), which calls for testing related to thermite and other pyrotechnics, and second, the extensive experience NIST investigators have with explosive and thermite materials.

9/11 Physics Truth

I started work on the 9/11 Physics Truth site last spring and finally got around to cleaning it up enough for release.

My intention is to present easy to read physics arguments that anyone can quickly understand and share with others, thus spreading the word and waking up more people. While we need to continue doing solid scientific research and presenting arguments that prove our case, we also need the support of many more people. The science is not that difficult for most people to understand, but we do need to do a better job of presenting it for easy understanding.

The site is a wiki, and I am hoping to get help from others to add comments, correct any misunderstandings I may have, create more graphics and videos, and fill in more of the detailed arguments, as well as address many other physics-related issues.

Physics Dept. Seminar on 9/10/2008 by Dr. Steven Jones at Utah Valley University

Dear friends and colleagues,

I have been invited to give a presentation at the Physics Dept. seminar of Utah Valley University on 10 Sept 2008, 4 pm, room PS-202. You are invited to participate. Here is the title and abstract:

9/11/2001: Forbidden Questions, Explosive Answers
By Dr. Steven E. Jones
Seminar at Utah Valley University, Physics Department
10 Sept. 2008, 4:00 pm, room PS-202

Why did three (not two) skyscrapers fall to the ground on 9/11 at near free-fall rates, killing thousands? Why were numerous bone fragments found on a roof-top 600 feet away? Why did the National Inst. of Standards and Technology, charged by Congress to explain the collapses, concede to us, "…we are unable to provide a full explanation of the total collapse"[1]? Why did NIST refuse to look for residues from explosives? (We, however, did so using state-of-the-art methods and I will report results.) What is the significance of red/gray chips found in the 9/11 dust? What is super-thermite? Who are the whistleblowers and what do they have to say? Why were there no air defenses on 9/11?

9/11 and Probability Theory

Frank M Legge (BSc, PhD)
10 June, 2008


There have been a number of authors who have drawn attention to the improbability of certain reported events that led up to the disaster that has become known as 9/11, in which three major buildings at the World Trade Centre collapsed with heavy loss of life. Both Boolean algebra and probability theory have been invoked as a means of estimating the likelihood that the official explanation of the event as a whole can be relied upon. (1)
The official explanation for the building collapses may be distilled from the reports of the investigations carried out by three government bodies: FEMA, (2) NIST (3) and the 9/11 Commission. (4)

Sydney Conference: 9/11 - Physics and Findings: Challenging the NIST Report

Dr. David Leifer, Registered Architect and Incorporated Engineer of the Faculty of Architecture, Design Science and Planning at the University of Sydney

In Sydney a conference is now under way challenging the official version and lack of investigation into what happened during the September 11, 2001 attacks in the USA.

Dr David Leifer, Registered Architect and Incorporated Engineer of the Faculty of Architecture, Design Science and Planning at the University of Sydney was the first speaker at the conference.

"We've all seen graphic video images of planes smashing into WTC 1 and 2 on 11th September 2001, we also saw in real time the two towers spectacularly collapse, for which it appears obvious to all that the impact of the planes and subsequent fires were the cause" he started his speech. Seemingly only a fool or subversive would question this chain of events..." he said.

Effective Email (Thanks to Myopicvoid and AboveAverageAmerican)

After reading a couple blog posts by Myopicvoid and AboveAverageAmerican (thank you for the insight by the way and I hope you aren't upset I "borrowed" your ideas). I put together this email that I then forwarded to everyone I know friends, family, etc. The response has been phenomenal! People who vehemently argued with me before are now, at least, admitting the official collapse explanation is not adequate. I could not believe the responses I received. One person said, and I quote," It was like someone suddenly turning on a light bulb." I am very encouraged by this and I owe it all to the sharing of ideas and strategies we have utilized on this site. Thanks to everyone, but in particular thank you to Myopicvoid and AboveAverageAmerican. Here is the email and you have my express permission to copy paste cut (as long as it stays within the general theme) or email to anyone you feel inclined to.

This email is slightly more complicated than my usual emails, however, I believe it is pretty striking when viewed in whole.

We need a comparative analysis between the WTC '93 bombing and the 2001 plane impacts

I have been spending the last few hours trying to come up with a way to compare the explosive forces between the '93 bomb and the plane impacts of 2001. However, my lack of expertise in this area of physics, pertaining to kinetic energy, explosive force, pressure, etc. is preventing me from making any sort of informed conclusion. On the other hand the information I have gathered suggests ( and I use that term lightly) that a bomb ( on the order of magnitude used in the '93 bombings: The bomb exploded in the underground garage at 12:17 P.M., generating a pressure estimated over one GPa (Giga Pascal) and opening a 30-meter-wide (98 foot) hole through four sublevels of concrete. The detonation velocity of this bomb was about 15,000 ft/s (4.5 km/s). Source: planted in the sub-level basement (which houses the critical main support for the tower) had a much larger probability of collapsing the building than an impact of a 767 carrying 10,000 gallons of jet fuel nearly 1,000 feet up from the basement.

Is It Really Simple Physics?

It's long but trust me, it's a quick read....

What do you all think about this? I remember the laws discussed in 8th grade science but I’m not into physics enough to know if any of this helps explain the "impossible collapse theory" . ANyone here into physics that could comment on this?

Simple Physics Reveals The Big Lie

Collapse Theory Fails Reality Check

On September 11, 2001, most of the world watched in horror as the Twin Towers of the World Trade Center (WTC) collapsed. People did not have to be tuned in at the time in order to have seen it; it was repeated ad nauseam on television for days.

In June 2005, in an apparent response to an article by Morgan Reynolds, Robert Gates, the former Director of the Central Intelligence Agency (CIA) and current Secretary of Defense stated (cached), “The American people know what they saw with their own eyes on September 11, 2001. To suggest any kind of government conspiracy in the events of that day goes beyond the pale.”
