Most of the fuel was vaporised on impact... ”


How do you know?
Atmospheric pressures and temperatures were not in a “vaporization” range. Likewise, vaporization does not negate conditions of fire and explosions of 8000 gallons of jet fuel. Even if vaporized the photos show the entire aircraft entering the buildings which would have contained the vapor/fuel.
James R said:
“ ...and if we accept that what fuel was left was enough to melt the structual supports then why did the top not topple off on both buildings... ”


Because the building collapsed straight downwards. You say the TV footage, didn't you?
He was asking why the buildings didn’t topple. You answered the non-asked question of, “how did the buildings collapse?
Jet fuel burns at approximately 800 degrees fahrenheit and the WTC structures were designed to take up to ~1300 ( or more)degrees before failing. It seems that conditions for a massive structural failure cannot be explained by jet fuel combustion alone. The collapse occurred straight down, as we all witnessed which demands that the failure of the structure over the first floor to collapse must have been exceptionally uniform. If one side of a floor began to collapse before another side the collapse would not have been symmetrically straight down and the buildings would have toppled.
This gets amplified when we saw both buildings collapsing with such manifest precision straight downward. An explanation screams for other than a “chance” perfection of conditions.

“ ... and what are the odds of all the steel supports failing at the exact same time as implied in the pancake theory, astronomical IMO. ”


They didn't fail at the same time. One or a few floors collapsed at the level where the planes hit. The lower floors collapsed when they were hit by the upper floors coming down on top of them.
There is still the uniformity of temperature conditions that must have existed in order to explain why one side of the first collapsing floor didn’t begin to collapse before another side, thus generating a collapse that toppled laterally instead of straight down.
More engineering and temperature analysis

“ This does not mean I believe any conspiracy theory on the matter only that a controlled demolition brought the buildings down. ”


Why don't you do a little reading about the building structure and why the collapse actually occurred, before jumping to conclusions? There's plenty of information available. The WTC was constructed in a rather unusual way, so that the floors were fixed to and supported by the building outer layer and the central core. When one or a few floors collapsed, the floors below were hit, and they were never designed to take the amount of weight. At a certain point in the collapse, the sides of the building also buckled.

Ranting about conspiracies without the most basic information makes you look a bit silly.
The conspiracy theories are supported by probable cause aren’t they? The links I found and included here are only the iceberg’s tip that contradict your implications. Especially telling is the lack of aircraft crash debris and fires consistent with a Boeing 757 impacting the pentagon building


Some NYC firemen on the job were emphatic that the collapsing of each floor was preceded by what they termed as a series of “pop” “pop” “pop” etc as if charges had been exploded. These firemen had been familiar with controlled destruction of buildings.
explosion data and evidence
There are media pictures
here is a good start of media information regarding collapse of the twin towers
James R said:
“ They did all fail at the same time. ”


No. You can quite clearly see on TV that the buildings collapsed from top to bottom.
Yes they fell straight down with the most precise of military order. The aircraft did not crash into the buildings dead center, The damage from the impact and heat was not symmetrical. I mean that in order for the first floor to collapse straight down the damage to that floor’s structural members must have been uniformly distributed over the entire floor. Otherwise, the most probable, is that the collapse would have been to one aside or another of the first collapsing floor. This would have resulted in a sideways topple which was not seen. are all that

James R said:
“ And when did the sides of the building buckle?No-one has ever seen the sides of the buildings buckle? ”


They buckled during the collapse. Remember the aftermath, with the piles of twisted building supports?
Some engineering analysis
There is also the damage that an adjacent building sustained before the collapse this building
James R said:
“ No OTHER concrete and steel building has EVER collapsed from FIRE. ”


I'm fairly sure you're wrong about that. But anyway, the WTC construction was fairly unique, as I said before.
I agree with the statement that no collapse has been mirrored by the WTC collapse, with the exceptions of controlled and intentional destruction of buidlings where carefully placed explosive charges dictate the collapse moide.
James R said:
“ And why did building 7 collapse?Do you even know about building 7? ”


Wasn't that right next door to the WTC?[.
Yes and some photos show billowing smoke around the time the time the buildings collapsed.

The simplicity of the data from the Pentagon attack is compelling. The lack of Boeing 757 aircraft crash debris and the expected fire fuel by 8000 gallons of jet fuel (kerosene) make it more than difficult to accept that the impact object was an American Airlines skyjacked Boeing 757y. No fan jest (6 feet in diameter), no landing gear, tail assembly, body parts of crew, passengers or Islamic Fundamentalist Terrorists, yet some 100 body and parts of Pentagon military and civilian employees were recovered. See the Crash in Shankesville, Pa, where again the absence of airplane crash debris makes it impossible to accept these two events as rationally being made by Boeing 757 aircraft.

Yet there was still molten metal at the site some time after the collapse, can you explain that? No-one else has bothered trying...
There was no molten steel at the WTC site. If this report is even true (perhaps you could link to it?), it could be aluminum or electrical solder.

Jet fuel burns at approximately 800 degrees fahrenheit and the WTC structures were designed to take up to ~1300 ( or more)degrees before failing.
IF the insulation around the steel survived the impact of an aircraft, which it didn't. Steel loses much of it's strength at HALF that temperature, to say nothing of uneven stresses caused by heat.

You fully accept a symmetrical collapse due to uneven stresses on the supports caused by a kerosene fueled fire?

Yes. Via catastrophic collapse and the inertia of the upper portions.

None of the exterior tubes are nearly of any strength to act as a hinge, which is probably what I deem you imagine in your head. In tower two, there was indeed a slight angle to the top portion's fall but largely because of the smaller mass.

The only substantial portion left to support were the interior columns. Substantially stronger, but in both cases still seriously damaged. Their interior positions 1)made them more susceptible to the fires, regardless of tilt or wind, and 2)made it more susceptible to a much greater moment immediately prior to the time of collapse.

That link only showed red hot metal, not melted steel. Care to try again?

And yes, I do believe that uneven heating stresses, mechanical damage, and loss of structural strength due to fire caused the collapse of the WTC's. After such loss of strength, the building would collapse downward due to gravity. In order to fall sideways or any other way, structural integrity would need to be preserved, which it obviously wasn't.

What you are saying, dkb218, is that not only did Bush and Co. orchestrate the bombing of two major office buildings full of people, but also the hijacking of 4 airplanes, deliberately aiming for the Pentagon and possibly the White House. It is beyond credulity that he could get the number of Americans required for such a mission to agree to such a thing. Especially since the Pentagon would be needed for any potential war.
Spidergoat,

What is remarkable about your post is the emphasis on "argument" and what you see as limits to facts based on your assesseent of "credulity". Contrast this with just the visual material contained in the media tapes of 9/11/2001 covering just the Pentatgon attack and the Shankesville crash.

In both events the absence of crash debris js inconsistent with the impacts of a Boeing 757 aircraft with both the Pentagon Building and the ground at Shankesville,Pa., respectively. Both events require the presence of scattered aluminum scraps that would make it impossible to avoid recognizing. The suggestion of some that the Pentagon Building absorbed the aircraft is specious and a manufactured description of the laws of physics. Three layers of two foot thick reinforced concrete walls require specifically designed military ordnance to manifest a forceful penetraion.

The main gear and two fan jet engines (with intake diameters of over six feet), reognizable portions of the tail and wing assemblies being totally absent from view should be enough "evidence" to negate any theoretical assumptions that these events were caused by the activities of Islamic Fundamenmtalists.

The damage sustained by the Pentagon Building does prove at least one thing: The object that impacted the building was very definitely not a Boeing 757 American Airlines, or any airplane of comparable size.

No passenger, crew or skyjacker body parts were recovered in either the Pentagon or the Shankesville, Pa. crash sites.

Your post attempts to smother reality because you cannot conceive of the reality that high placed individuals in the United States Government have been actively pursuing the replacement of our constitutional government with one of limitiless exercise of power. Bush is the eight president in succession since the couip d'etat of November 22, 1963, which should be obvious to the most casual of observation. The successful completion of the 911 mission could only ahve happened with the cooperation and acttive supoport of many highly placed individuals in our government. We can all determine who is ignoring the facts of 911 and who is steering the attention of the public to other matters.

This thread is intended to discover just what indeed resulted in the collapse of the Twin Towers. The answer is staring us all right in the face.

When the towers collapsed they did so straight down. The first floor to give way did so uniformly over the entire surface of that floor. If we are to believe that the fire fueld by the jet fuel on board the two aircraft heated the steel support structures to the point of 'giving way' then those structures must necessarily have weakened uniformly over the entire floors that first collapsed.

This iuniformity of the loss of structural integrity must have been duplicated in both towers, not just one. The scientific level of confidence in the probability of both of these events occuring randomly is vanishlingly small.

Jet fuel, kerosene, burns at 800 degrees fahrenheit. The steel girders supporting the weight of the building were designed to sustain heat of up to near 2000 degrees F. Even assuming that the supporting strength of the structural steel was weakened at lower than 2000 degrees, the fact remains that the beams had to fail uniformly over the entire floor area of the individual towers, otherwise the building would have toppled sideways instead of straightr down.

Whjat can sup[p[ort the observed "straight down" collapse mode? Firemen at the scene described the collapsing as accompanied with a series of explosions that preceded each colpasing floor. These firemen had experience and training in the controlled implosion of buildings designed to be removed. This requires the placement of explosiove devices at key points in the floors of the building.

You Spidermonkey, arguing that Bush could nbot have gotten hundreds of "Americans" to go along with his plotg is indicative of themost naive and childish understanmding of the history of our country and the world the past 40 years. You want us to believe that Americans are incapable of creating tyranny and a political state governed by the gun.

With a War on Terror just beginning to gather momentum the intentions of the plotters should be acutely obvious. With the US Constitution being trashed with impunity by a cooperating Congress and Judiciary, all sincerely suppported with a press that is certainly not free, the integration of the war on drugs with the phony war on terror, what you see is what you get.

The Constitution (Article III) defines treason as conducting war on the United States, which certainly the 9/11/2001 such acts of war. Also, included within the definition of treasopn, are acts that give aid and comfort to the enemies of the United States, which certainly include giving any support, aid and/or compfort to the actual persons carrying out the physical operation resulting in the murder of thousands of persons and the destruction of massive amounts of property.

Any act in abetting or assisting the furtherance of the conspiracy is also treasonable. I might also infoirm you that treason, of the kind demonstrated by those criminals of 911 are subject to the termination of their lives by the sudden jerk on their scrawny necks when they come to the end of a rope tied around their scrawny necks.

At the very least their is certainly probable cause to believe in the existence of the domestic plot resulting in the 911 attacks, an act of war. The plot has reached a point where the present occupant of the White House, certain members iof Congress and the HJudiciary, have exceeded the lawful limnitation of their activity by the treasonable and other abusive exercise of government power.

Hundreds of thousands of persons whose lives were sacrificed over the years during their committed support and defense of the Constitution of the United States. Is all of that to be swept aside in some kind of debate, or are those who are able to discern at least some of thge truth able to develop a personal committment to do the right thing when the opportunity arises, and when the "right thing" is, from their personal perspective, necessary as an act of preservation of their country.

Absolutely correct.
Remarkably accurate.
A really astute perception.
A casual observation could indeed lead to that conclusion. Fortunately, most of us make more than casual observations and so arrive at different conclusions.
 
geistkiesel,

Bullshit.
You rightly suspect the Bush administration of a cover up, but then you go way off in left field someplace and make totally unsubstantiated conclusions from incomplete evidence. Just one look at GWB's face after he was told, and it's clear, they were arrogant in their complacence and caught off-guard by the attack.

Your amature analysis of the WTC collapse is incorrect. The fireproofing on the steel girders broke off due to the airplane's impact. The fire was enough to weaken the steel, and cause a catastrophic collapse, which, due to gravity and the huge mass involved, fell almost straight down. Period.

Yes, the Bush administration took advantage of the attack to further their pre-determined goals, but they didn't plan 9/11. Maybe they just ignored the warning signs because they wanted something like this to happen.

It says that the most plausible answer is most likely the truth, doing too much thinking can lead just as far away fromthe truth as doing too little. Before you accuse anyone of seeing through rose colored glasses we should just remember that you are a follower of the arab faith and hence have a vested interest.

Again if 9/11 was carried out by the powers that be as a reason to invade iraq why wasn't there a more direct link to saddam? As it was even after 9/11 Bush and co had to come up with other links and accusations to try and justify the invasion, pretty damn sloppy work for the criminal masterminds wouldn't you say.
Sloppy perhaps but they have gotten away with it so far. You realize that the US supported Iraq in the Iraqi-Iranian War do you not? The powers that be did use the 911 attacks as justifiying not only the invasion of Iraq and Afghanistan, but the formation of the massive police state entity known as "Homeland Security".

Bush has admitted his assessment of the intelligence materials used in his energetically delivered justification for invading Iraq was in error, and yes it was sloppy, and it is this sloppiness that has led to the exposure of the conspiracy.

The arrogance of the comspirators, government and corporate, is one of believing in their collective position of supreme power; that no organized activity of the people will be able to undermine and destroy their criminal enterprise.

You Sock-puppet, realize that Bush is just a successor president in the line of seven who preceded him since the coup d'etat of Novemver 22, 1963, do you not? You are either assuming that the Bush regime is solely responsible for all the activities of the US Government leading up to 911, or you are attempting to create that impression. This country of ours has a history you know?

Now the country is being saturated with propaganda attempting to justify the destruction of Iran (Syria, Libya etal) because the Iranians are in the process of developing nuclear weapons capability. The underlying assumption in all of this is that the US is the moral leader, the element of good, while the Islamic Iranians and all the Arab radicals need to be reined in, controlled and contained in secret CIA prisons and even in visible US Marine Corps operated prisons. Israel has developed and prodiuced nuclear weapons yet no hue and cry is directed towards them, and who believes that the Israelis would hesitate to use these weapons?

If you familiarize your self with the reality in Iran at the time of the Shah, the US Government was deeply imbedded in the internal affairs of Iran especially in the SADAK(?) a CIA creation and supported secret police of the Shah's government. That regime was forcefully manipulating the religious practices of the Iranian people in order to "bring them into the modernized 20th Century".

How would you react if a foreign power used their influence in the pracatice of religion in the United State? If you are the sort that wonder why "they hate us" as theyu do, well just open your eyes and see for yourself just how caring and freedom loving this, the United States, our country which is our, the people's responsibility, has used it's gross military power and enormous wealth to trash the fundamental structures of many smaller and weaker nations whose econmomic and social structures impede the path along our destined road to economic and political supremecy of the planet.

Sock-puppet has accused another of looking through rose colored glasses because that other was of the Islamic Faith. What are the color of Sock-puppets glasses? What is Siock-puppet's agenda? Who is Sock-Puppet supporting? Why cannot Sock-Puippet see that the factual matters recorded by the media on 911 belie any rational conclusion that the attacks were of an alien origin and that indeed the entire country's attention has been diverted from the direction of the domestic conspirators that must have access to powers in the highest levels of government.

Sock-puppet is just that, a puppet. The only alternative explanation for the nature of his posts is his active membership in the cabal giving aid, support and comfort to the traitors that planned and conducted acts of war on the United States on 9/11/2001.

The solution to our problem, ultimately? The sudden jerk felt by the convicted traitors of 911 as they come to the end of the rope looped around their scrawny necks.

Right, and Roosevelt planned Pearl Harbor in order to justify invading Europe. You people are paradoxically cynical to the point of naivety.
 
anomalous, oops i mean humanist
your poll is not accurate
you did not include the option of what actualy brought down the towers

IF the insulation around the steel survived the impact of an aircraft, which it didn't. Steel loses much of it's strength at HALF that temperature, to say nothing of uneven stresses caused by heat.
The emginmeeriong reports I read indicated the steel structures were designed to fail at 2000 degrees fahrenheit. Your suggestion that the heat insulation protecting the streel structures is indeed spurious. However, the exact mode of structural integrity loss be it temperature induced failure or otherwise, is of secondary importance.

In order that the floors of the towers collapsed in a straight down direction and did not topple to one side, requires that the first floor that collapsed failed uniformly over the entire floor area. If the north side of the floor collapsed before the eastern side, or the southern side, then the building would have toppled accordingly.

The uniformity of heat induced structural failure requires uniform distribution of the heat, here the fire. How likely is this uniform diustribution of fuel, fire, heat and structural failure over the entire floor area? It is highly unlikely, to the degree of impossibility. Add to this little problem of statistical improbability is that both buildings must have had an identical uniform distribution of fuel, fire, heat and structural failure.

Then there is the problem of the trained and experienced firemen who stated they heard the sounds of explosive charge detonations preceding the collapse of floors as the building went straight into the ground, pop,pop,pop,pop . . .. These firemen talked about previous exposure to the controlled destuction of buildings where explosive charges are placed in critical positions within the building to control the direction of collapse of within a predefined acceptable area.

I have never heard of this statement anywhere in the structural engineering department here.

Can you provide the links other than the single-handed Utah skeptic that can provide some better grounds for this?

Try "MAXIM".
Exposing the criminals to the latest "hotty" that has rattled my bones would be an act of "unfair" warfare, would it not? I feel morally bound to use no weapons of mass distraction as I proceed to do what I am able in protecting my country from the threats of domestic treason.

Do you understand the difference between failure and diminished strength? If you have such a poor understanding of materials science that you are unaware that the properties of the steel would have been radically effected by the elevated temperature, then why are you posting as if you knew what you were talking about.
In addition to the effects on yield strength, note that the thermal expansion of the beams would create severe stresses within an already weakened structure.
In short, you have not properly considered this incident because you lack the skills and knowledge to do so.
Retire gracefully and we shall forgive you your tresspasses.
 
"designed to fail at 2000 degrees"
Assuming the fire insulation stayed on, which it didn't.

Actually, the top of one of the towers, I'm not sure which, did fall to one side a little. How can you dismiss the subject of steel fire insulation? That seems central to the issue. Steel will lose much of it's strength at about 700 degrees, much less than the burning temperature of jet fuel.

The so-called "uniform" distribution of heat induced failure can be explained by the nature of the floors, which were open except for a central core.

The sounds of popping are not unexpected given the catastrophic nature of the event.
