You don't understand the meaning of contribute do you? If I put a pitcher under the sink and turn on the faucet it will fill up with water. If i also pour water from a bottle it will fill to faster. Now it would have filled up without the bottle of water but that doesn't mean the bottle of water didn't contribute to the filling of the pitcher.

Now if you want to use the NIST report which says there were no explosives your expertise can not be taken,seriously.

If the debris hadn't fallen from WTC-1 then there would have been no fire in WTC-7.

So how can you possibly say that debris falling from WTC-1 had no bearing on WTC-7 collapsing..

Don't say the NIST report says that either, because the opening line of the abstract reads :

This report describes how the fires that followed the impact of debris from the collapse of WTC 1 (the north tower) led to the collapse of WTC 7

Read my post again invictus and you owe me

What are you talking about?

So how can you possibly say that debris falling from WTC-1 had no bearing on WTC-7 collapsing..

I didn't say that....that is what I am talking about

I don't see a quote or a link in that post, so unless I am a mind reader or you hid the link in some sort of irish cipher it would have occurred to me that was your theory.

The same falling objects that set the fires caused damage by being big enough to punch through the building exterior. There were plenty of eyewitness accounts of SOME of what had been damaged as firemen inspected the building.

So, once again, flying debris damaged the building and started fires. The fires subsequently caused enough additional damage to cause the building to fall. Once again it is a matter of semantics, did the falling debris cause the building to fall or the fires caused by the falling debris to cause the building to fall? The answer is moot. It is all part and parcel of the same thing. In both cases, the Twin Towers and Building 7, if acting alone, the fires would have brought the building down anyway. It would just have taken a little longer.

In none of the cases were the impact damage caused by planes or falling debris enough, by themselves, without the subsequent fires, to bring down the buildings.

The physics behind the sequencing and causes is called Failure Mode Analysis in building failures.

No evidence of ray gun use was found.

Between you and the Swiss Genius not paying attention I despair .

I knew it with heat intensification a fire can get hot enough to melt steel, which was my theory I stated it before. The fires got hot enough to cause enough damage to the main beam supporting th e building........I believe it is a plausible explanation........oxygen ignitor and jet fuel all over the place can cause one hot fire......think about blacksmiths' and how they melt metal.....2500 degrees fahrenheit

Structural steel will fail far below the melting point. At the usual loads structural steel is designed to resist, it only takes around 1000 degrees to cause the steel to bend. Building seven was supported by two vertical trusses which were much more susceptible to heat damage than steel columns.

There are reasons to believe that NIST, while preparing its reports on the World Trade Center, was functioning as a political agency of the Bush-Cheney administration, rather than a scientific agency.

Suspects in a crime are usually not put in charge of investigating that crime and all of the official investigations of 9/11, including the NIST investigation, were carried out by representatives of the Bush-Cheney administration.

When a crime has been committed, both common sense and the law dictate that persons suspected of committing that crime should not be put in charge of the investigation. The two major suspects for having committed the 9/11 crimes are Osma bin Laden and al-Qaeda, on the one hand, and members of the Bush-Cheney administration, on the other.

The number of people who question the official report is significant. Less than half, only 48 percent, of the American public expressed confidence that the government and the 9/11 commission had not engaged in a cover-up.

The assumption (and accusation) that all the people who have publicly expressed skepticism about the official story consists of "kooks" and "crackpots." The falsity of this assumption is demonstrated by the existence and membership of various scholarly and professional organizations that have emerged.

These organizations includ Architects and Engineers for 9/11 truth, Firefighters for 9/11 truth, Medical Professionals for 9/11 truth, Pilots for 9/11 truth, Political Leaders for 9/11 truth, Scholars for 9/11 truth and Justice (which includes a large Scientific Panel Investigating Nine-Eleven.

As these polls and organizations show, large numbers of people in the United States and around the world, many of whom are well educated and some of whom have professional expertise specifically relevant to evaluating the official account of 9/11 believe that the Bush-Cheny administration did not tell the truth about the attacks. A significant portion of these people believe tht the attacks were, in fact, orchestrated or at least facilitated by members of that administration.

Given this context, no one can responsibly dismiss as irrelevant the fact that people who are suspected of facilitating, or at least of covering up a crime are normally not allowed to run the investigation of that crime.

Any investigation of 9/11 run by representatives of the Bush-Cheny administration must be considered illegitimate in principle (just as as any investigation run by al-Qaeda). And yet every official investigation of 9/11 thus far has been carried out under the direction of representatives of this administration.

Although the 9/11 Commission, although it was widely called an "independent" commission, the 9/11 Commission was, in reality, not at all independent from the Bush-Cheney White House.

The executive director was Philip Zelikow. The Commission's work was done by Zelikow and the 85 members of his staff, all of whom worked directly under him. This meant that, as New York Times reporter Philip Shenon wrote, none of the commissioners had a "staff member of their own, typical on these sorts of independent commissions."

Zelikow thereby prevented any of the commissioners from striking out jon their own in the investigation. Besides directly the staff's work, telling them what to investigate (and hence what not to investigate) Zelikow was largely responsible for the Commissions' final product.

Zelikow had secretly outlined this 9/11 report and hence had determined its conclusions in advance, before the Commission's staff had even begun its work.

This is important because Zelikow was essentially a member of the Bush White House. He was especially close to Condoleezza Rice.

anyone that thinks it was possible to plant enough explosives in those buildings prior to 9-11 to bring them down is a kook and crackpot..

the reasoning behind Jones and his Nano-Thermite theory is based totally on the fact that only a kook and crackpot could possibly believe that a standard demolition procedure was carried out.

knowing the amount of people, the amount of time, the amount of work necessary to prep those buildings for a controlled demolition is not a theory that can stand any critical scrutiny.

they know that.

they know just as well as anyone,that those Explosives would have cooked off in no time!
Only Place they don't do is in Dimmsdale where there are Cosmo and Wanda,the Fairy Godparents!

Not very useful for a controlled Demolition!
Then there is the Timefactor in rigging the Building,and hiding the Activity and Explosives!
Explosives cook off well below 300 Celsius!

Wonder how they think one could keep the Detonations in Sequence when your Explosives go off unpredictable all over the place!
Guess in their Universe it will be possible!

By making an Eutectic Mixture with Sulfur,for instance!

Not only that, almost everyone who has the ability to actually analyze the structural failures at 9/11 are members of ASCE. The government did not provide the analysis, they hired people who hired people to do it.

The analysis of hundreds of more members of ASCE have gone over everything published and every conceivable aspect independently and published their papers for peer review. There is no chance of the US Government having any influence on the ASCE due to the peer review process and the size of the organization.

Just like these threads, you never find a truther wanting to discuss ASCE or their findings because real science and logic do not fit into their story.

Everyone is wrong a man dressed up like the construction guy in The Village People went in there with a cordless saw zaw and a macdaddy blade in it then started cutting I beams.They found him in the rubble and just before he died his last words were "they should have a YMCA in the navy for the Macho Man"

an interesting side note that doesn't often get discussed is the fact that each plane was constructed with about 30 tons of aluminum. aluminum liquifies at 1220F. liquified aluminum mixed with water turns into a nasty, highly explosive hydrogen vapor.

Aluminum burns easily. It is the major ingredient in some solid rocket fuels.
