Yet another peer reviewed paper from a respected Journal finds the towers were doomed to collapse.
9/11 demolition theory challenged
An analysis of the World Trade Center collapse has challenged a conspiracy theory surrounding the 9/11 attacks.
The study by a Cambridge University, UK, engineer demonstrates that once the collapse of the twin towers began, it was destined to be rapid and total.
One of many conspiracy theories proposes that the buildings came down in a manner consistent with a "controlled demolition".
The new data shows this is not needed to explain the way the towers fell.
Resistance to collapse
Dr Keith Seffen set out to test mathematically whether this chain reaction really could explain what happened in Lower Manhattan six years ago. The findings are published in the Journal of Engineering Mechanics.
Previous studies have tended to focus on the initial stages of collapse, showing that there was an initial, localized failure around the aircraft impact zones, and that this probably led to the progressive collapse of both structures.
In other words, the damaged parts of the tower were bound to fall down, but it was not clear why the undamaged building should have offered little resistance to these falling parts.
"The initiation part has been quantified by many people; but no one had put numbers on the progressive collapse," Dr Seffen told the BBC News website.
Dr Seffen was able to calculate the "residual capacity" of the undamaged building: that is, simply speaking, the ability of the undamaged structure to resist or comply with collapse.
His calculations suggest the residual capacity of the north and south towers was limited, and that once the collapse was set in motion, it would take only nine seconds for the building to go down.
This is just a little longer than a free-falling coin, dropped from the top of either tower, would take to reach the ground.
He added that his calculations showed this was a "very ordinary thing to happen" and that no other intervention, such as explosive charges laid inside the building, was needed to explain the behavior of the buildings.
The controlled detonation idea, espoused on several internet websites, asserts that the manner of collapse is consistent with synchronized rows of explosives going off inside the World Trade Center.
This would have generated a demolition wave that explained the speed, uniformity and similarity between the collapses of both towers.
Conspiracy theorists assert that these explosive "squibs" can actually be seen going off in photos and video footage of the collapse. These appear as ejections of gas and debris from the sides of the building, well below the descending rubble.

-so, we have yet another peer-reviewed paper disagreeing with the crazy people. funny how the other side has yet to produce 1. i wonder why that it??
Great there you go again posting garbage from debunking911.com
The site just like the Popular Mechanics hit pieces are meant to spit out the same old dis-information over and over.
Maybe you forgot to read the important information out there regarding what CIA officials think about 911.
Seven CIA Veterans Challenge 9/11 Commission Report
September 23, 2007
September 23, 2007 � Seven CIA veterans have severely criticized the official account of 9/11 and have called for a new investigation. �I think at simplest terms, there�s a cover-up. The 9/11 Report is a joke,� said Raymond McGovern, 27-year veteran of the CIA, who chaired National Intelligence Estimates during the seventies. �There are a whole bunch of unanswered questions. And the reason they�re unanswered is because this administration will not answer the questions,� he said. McGovern, who is also the founder of VIPS (Veteran Intelligence Professionals for Sanity), is one of many signers of a petition to reinvestigate 9/11.[1]
During his 27-year CIA career, McGovern personally delivered intelligence briefings to Presidents Ronald Reagan and George H.W. Bush, their Vice Presidents, Secretaries of State, the Joint Chiefs of Staff, and many other senior government officials. Upon retirement in 1990, McGovern was awarded the CIA�s Intelligence Commendation Medallion and received a letter of appreciation from then President George H. W. Bush. However, McGovern returned the award[2] in 2006 in protest of the current George W. Bush Administration�s advocacy and use of torture.
In his blurb for 9/11 and American Empire: Intellectuals Speak Out,� edited by David Ray Griffin and Peter Dale Scott, McGovern wrote[3]: �It has long been clear that the Bush-Cheney administration cynically exploited the attacks of 9/11 to promote its imperial designs. But the present volume confronts us with evidence for an even more disturbing conclusion: that the 9/11 attacks were themselves orchestrated by this administration precisely so they could be thus exploited. If this is true, it is not merely the case, as the Downing Street memos show, that the stated reason for attacking Iraq was a lie. It is also the case that the whole �war on terror� was based on a prior deception. This book hence confronts the American people---indeed the people of the world as a whole---with an issue second to none in importance and urgency. I give this book, which in no way can be dismissed as the ravings of �paranoid conspiracy theorists,� my highest possible recommendation.�

Dr. Frank Legge from Australia continues his diligent efforts to reach the public regarding 9/11 issues with his paper on the collapse of WTC 7 sans math, in an article entitled: "9/11 � Proof of Explosive Demolition without Calculations"
9/11 � Proof of Explosive Demolition without Calculations
There is at least one Aussie with some common sense.

just something else to muddy the waters here..
Can someone PLEASE explain the photo on the top-right? Ignore everything else on the page and explain that pic plz.
http://physics911.net/gallery/
The spark of light on the left is the nose of the plane touching the WTC. There is no way this little impact had time to create a shockwave that blows out the other side of the building..
looks to me like preplanted explosives going off in that building, timed to coincide with the airplane strike (a simple RF proximity sensor could do this).

Let me hazard a guess. This is not a still photo. The plane was moving at a very high velocity. In this one single frame, the camera caught the plane as it was about to hit the left end, and over the duration of the frame, the plane crashed right through the building and was about to explode towards the other end of the building. The smoke you see is probably just milliseconds before the whole thing exploded. Sounds logical ?
It's actually quite likely that the plane exploded somewhere near the left end of the building. The pressure waves that developed, then traveled at supersonic speeds and out of the building walls.
I think this is the case because I did the math and it doesn't add up to what I said in my previous post. A plane cannot travel the distance of the WTC breadth within a frame, if it's traveling at the reported speed. Besides, the impact will abruptly change the speed so it cannot proceed with the same speed after the impact.
A commercial camera usually captures 24 frames per second. So one frame is about 0.0417 of a second. With the max speed given (it says between 500-800 kmph) the plane can only travel a distance of 9.3 meters in 0.0417 in free air. The width of the building is about 63 mts. If we assume that the plane traveled some distance into the building before exploding, it must atleast have traveled 10 meters or less (this is my guess, but it seems logical that the passenger plane cannot explode immediately on impact. It's not a missile. Or is it ?
) If you look at the frame, you see the smoke starting anywhere between 1/6th-1/4th of the distance of the breadth of WMC, from the left end.
So, the plane impacted the left side and exploded within 10 meters of the left end. The blast pressure waves traveled at supersonic speeds and ripped out the building. All of this happened within one frame and it got captured on the video. That is my best explanation of the event.
