39. From what I read
Thu Aug 7, 2014, 06:44 PM
Aug 2014

before 9/11 there were actually no steel-framed skyscrapers that have ever been demolished by a controlled demolition, surprisingly enough.

may or may not be true, but recalling all the videos I ever saw of known and acknowledged controlled demolitions of tall buildings I realized they were all made of concrete or steel-reinforced concrete. they were not steel-frame skyscrapers. so if what I read is true then the WTC towers could be the first modern steel-frame skyscrapers to be brought down that way.

sort of makes sense. explosives would be ideal for blasting through concrete pillars and supports.
but thermite, an incendiary commonly used by welders to cut through thick steel, may be more suited for cutting through the structural steel columns and beams found in steel-framed skyscrapers.


Civilian Uses
Thermite reactions have many uses. Thermite is not an explosive; instead it operates by exposing a very small area of metal to extremely high temperatures. Intense heat focused on a small spot can be used to cut through metal or weld metal components together both by melting metal from the components, and by injecting molten metal from the thermite reaction itself.

http://en.wikipedia.org/wiki/Thermite#Civilian_uses


the bolded would explain the large pools of molten metal witnesses saw in the aftermath of the collapses.

43. No 47-story building has ever been CD'ed, by any method
Fri Aug 8, 2014, 09:00 AM
Aug 2014

The tallest steel-framed building ever demolished with explosives was the 28-story J.L.Hudson Department Store in Detroit (and actually, only a small part of it was that tall). Watch this video and then try again to tell me how WTC7 was anything like this:



Even though this building was considerably shorter than WTC7, it was a major technical challenge:

Double column rows installed in the structure between vertical construction phases, internal brick shear walls, x-bracing, 70 elevators and 10 stairwells created an extremely stiff frame. Columns weighing over 500 lb/ft, having up to 7.25 inch thick laminated steel flanges and 6 inch thick webs, defied commercially available shaped charge technology. CDI analyzed each column, determined the actual load it carried and then used cutting torches to scarf-off steel plates in order to use smaller shaped charges to cut the remaining steel. CDI wanted to keep the charges as small as possible to reduce air over pressure that could break windows in adjacent properties.

http://www.controlled-demolition.com/jl-hudson-department-store

It's fair enough to say that it's theoretically possible to demolish a 47-story building with either explosives or thermite even though neither has ever been done (and even though there it's never been demonstrated that cutting a heavy column with thermite is actually possible). However, it's intellectually irresponsible to fail to consider what either would entail, and to simply imagine that either could be done in secret, in an occupied office building, in such a way that it would look like exactly like a progressive collapse caused by loss of structural integrity.

The NIST hypothesis was formulated through quantitative, physics-based analysis by dozens of structural mechanics experts, most of whom were from private industry. The CD hypothesis was concocted using imaginary physics by people who apparently don't know anything at all about structural mechanics. The NIST hypothesis does a credible job of explaining ALL the evidence, whereas the CD hypotheses falls completely apart if all the evidence is considered. When asked to justify and substantiaate such a ludicrously implausible hypothesis as CD, the best "truthers" can do is to say, "If it looks like a CD, then it must be a CD," while ignoring that the premise is not sound and that the logical inference is not valid. "Truthers" expect people to ignore that and instead just count how many signatures Richard Gage has garnered with his disingenuous presentations.

but it wouldn't be that hard to rig the building.
it would be done under the guise of doing renovation and repair work.

skyscrapers undergo routine repairs, maintenance and construction/renovation work done to them all the time. work crews could simply close off and evacuate each floor of the building one at a time, and no one could see or figure out what they were doing.

and no modern building, steel or concrete, has ever collapsed because of fire. the idea that building 7 was brought down by a minor office fire that was isolated to one or two floors and melted its steel columns is laughable. it wasn't a towering inferno. and in the past when buildings caught fire and became great big towering infernos on multiple dozens of floors, blazing for hours and hours on end, guess what? they still remained standing tall after the fires were put out and did not collapse.

WTC 7 was a major fire, not fought. You lie about the fire, they burned unchecked.

High-rise buildings that did not collapse, fire were fought. No fires in 1, 2, or 7 were fought on 911.

911 truth lost this BS, but they can try harder with Bigfoot, they can use the same evidence, aka nothing.

One Meridian Plaza was evacuated because it might collapse, it was on fire, it was never was used again.
Many buildings have been totaled by fire, steel fails in fire, 911 truth lies, two facts true.

You should do some research before spreading lies about 911. A building totaled by fire, steel...

Fire can't bend steel... fires fought keep buildings standing, but can't save them. Office fire, little office fire did this, oops, 911 truth lied, you are spreading the lie of little fires... Why

Never used again!!! Like WTC 7, but it did not fall, it was taken down, too damaged to be used again, BY FIRE. 911 truth lied.


Wow, steel fails in fire. Who knew, 911 truth has no clue.

911 truth lies, fire destroys, "ordinary" fires. 911 truth lies about fire, why did the people jump if WTC fires were small? Why does 911 truth lie? Why do you support idiotic lies.

In the 13th year of lies, 911 truth fails on fire.

its actually two buildings in one. the main part of the structure is only 5 or 6 stories. the skinny part in front of the main structure is 13 stories, which is the part of the building that collapsed, and even then it was only a partial collapse of the secondary structure. and 13 stories is no high-rise. the other thing is, the 13 stories of the secondary structure is almost the same height as the main structure at 6 stories.

the most significant thing to know is that the main structure of the Delft Technology building, which was not a highrise , remained standing after the fire was put out. whereas the twin towers and building 7, on the other hand, were total collapses of high-rises where nothing remained standing.

to try to compare them reeks of desperation because they are in no way comparable.

Tue Aug 5, 2014, 11:12 PM
Aug 2014

indicates a controlled demolition, but not a standard one where the structure is imploded and contained more or less into its own footprint.

speed of collapse is much too fast to be explained by pancaking floors. and I use the term collapse loosely because it is not a collapse but is being exploded from the top down at a tremendous rate of speed. what kind of force could create temperatures high enough to melt steel and reduce a modern 110-story skyscraper to a pile of dust within a matter of seconds? only thing I could think of is advanced military-grade explosives to pull off something like that. certainly not an office fire can do that.



An explosion is a rapid increase in volume and release of energy in an extreme manner, usually with the generation of high temperatures and the release of gases. Supersonic explosions created by high explosives are known as detonations and travel via supersonic shock waves. Subsonic explosions are created by low explosives through a slower burning process known as deflagration. When caused by a man-made device such as an exploding rocket or firework, the audible component of an explosion is referred to as its "report" (which can also be used as a verb, i.e., "the rocket reported loudly upon impact".)

about the Pennsylvania flight. may very well be true.

I think Bdlg 7 was supposed to come down at the same time as the twin towers so the larger buildings could mask the destruction of Bldg 7. but there was a technical glitch and it failed to come down as planned. which meant that when it did come down later in the day the whole world could see Bldg 7 was an obvious CD. so then they were forced to come up with their ridiculous story of office fires as the cause of the collapse.

Wed Aug 6, 2014, 12:43 AM

in other words it shouldn't have collapsed at all.

pancaking floor by definition would create a decrease in acceleration (and corresponding increase in time) - a jolt or interruption - every time the pile driver hit another floor on its way down. but that is clearly not the case with the wtc buildings. in fact the buildings are actually accelerating, the same type of smooth acceleration you expect from an object in freefall with nothing below it to break its fall until it reaches the ground, with no jolts.

what happens when you hit a standard steel nail with a hammer? the fall of the hammer is interrupted and is actually stopped in its tracks when it strikes the nail. you then must lift the hammer up high above the nail and strike the nail once again, and again, and again until the nail is driven all the way into the wood. the hammer doesn't just keep falling as if the nail wasn't even there. the nail isn't just going to give way on the first strike, or even the second or third strike of the hammer.

in short the pancaking/pile driver theory is not possible under the known laws of motion and physics. its utterly absurd.

Wed Aug 6, 2014, 12:51 AM
Aug 2014

I did a simple one myself several years ago, and the collapse times I calculated were pretty close to the times reported by NIST. You shouldn't notice much of a deceleration once the collapse gets underway because the difference in mass between the falling portion and subsequent floors is quite significant. Jolts, if at all measurable in collapse initiation (good luck finding decent locations to measure from), soon become insignificant compared to the overall noise in the collapse mechanism.

that might be true if the building was made out of balsa wood and toothpicks. then maybe fire could have turned it into a pile of ashes within a matter of seconds. but 90 floors and 47 core columns made of the strongest structural steel known to man...is going to provide quite a massive amount of resistance to the alleged pile driver or falling upper block which supposedly consisted of the 10 or 20 floors above the impact zone.


Physics 101: for every action, there is an equal and opposite reaction.

hence the upper block isn't going to destroy the much more massive lower block, without first destroying itself, long before it can reach the ground. so the official explanation, is beyond ludicrous.

Wed Aug 6, 2014, 01:29 AM

It's scarily easy for the collapse to progress to completion once initiated, because the individual columns are loaded beyond their capacity by the failure of others. The math is pretty simple if you have the geometry laid out correctly and your materials modeled appropriately. Even the baseline loads calculated for the towers by NIST had some structural members (including both perimeter and core columns) with DCRs greater than 1.0.

Your "Physics 101" claim isn't going to do much good if you don't allow for all the relevant forces. Neglecting gravity is going to cause problems in your model, because that's the reason the falling mass doesn't just disappear. That mass has to go somewhere, and the dominant force acting on it is gravity, so it goes down.

I'm pretty sure the engineers and architects took that into account when they designed the wtc buildings.

please show me a real world example or experiment where one object can completely destroy another object made of the same material and mass, using the force of gravity alone, without destroying itself in the process, while falling at the same rate of speed of the twin towers. with smooth acceleration all the way through, without jolts or interruptions.

Your application of that particular law, however, is not appropriate. Neither is your strawman in the second paragraph.

I do recommend, though, if you are trying to convince people of something you should probably stick to terms and concepts with which you are familiar. Your description of the collapse of the towers indicates you are not as familiar with basic physics as you might think. Terms like "speed" and "acceleration" have specific meanings, and you've managed to jumble them up into an incoherent mess. This is not uncommon for laypeople, but is an excellent example why some discussions aren't meant to include everyone. Perhaps you should just leave this to the experienced professionals?

22. Asking for a real world example
Wed Aug 6, 2014, 02:21 AM
Aug 2014

is a strawman is in your universe? I don't know where you are from, but here on earth science is conducted with real world testing and experiments not just theories and ridiculous claims. it can't be called science if you can't prove it.


This is science:

The scientific method is a body of techniques for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.[1] To be termed scientific, a method of inquiry must be based on empirical and measurable evidence subject to specific principles of reasoning.[2] The Oxford English Dictionary defines the scientific method as "a method or procedure that has characterized natural science since the 17th century, consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses."[3]

http://en.wikipedia.org/wiki/Scientific_method




This is non-scientific hocus pocus voodoo aka the NIST report:

NIST official FAQs
22. Did the NIST investigation look for evidence of the WTC towers being brought down by controlled demolition? Was the steel tested for explosives or thermite residues?

NIST did not test for the residue of these compounds in the steel.

23. No, that's not a strawman.
Wed Aug 6, 2014, 05:25 AM
Aug 2014

However, there is a world of difference between the paragraph I referenced and an accurate description of the collapses. That paragraph is a strawman, because it asks for a "real world example or experiment" supposedly with the purpose of validating the science behind the collapses by example, but the description is incorrect and the idea itself depends on an understanding of the science that is wholly lacking. It is not necessary to have witnessed a prior event that matches the characteristics of the event in question in order for us to understand the behavior.

Again, perhaps this should be left to experienced professionals. Engineering through Google isn't sufficient for the task, at least in your case.

I ask you for a real world example to back up and prove your ludicrous claims.
You choose to keep blowing hot air.

Do you not understand the question? Let me repeat it for you.
Try reading it slowly this time, maybe that will help.

please show me a real world example or experiment where one object can completely destroy another object made of the same material and mass, using the force of gravity alone, without destroying itself in the process, while falling at the same rate of speed of the twin towers. with smooth acceleration all the way through, without jolts or interruptions.


Failing that, try enrolling in an Introduction to Physics course at your local community college. Maybe they could help you to finally grasp and comprehend this simple request , and perhaps explain to you how Newton's Laws of Motion works. Then get back to me and let me know if you learned anything. It's not rocket science (but apparently for you it is).

However, I have performed calculations myself that confirm my conclusions, and they are far more robust than those performed by the truth movement. Official coverups of political issues aside, the collapses were mostly as described in the NIST reports. Both the duration of the collapses and the so-called symmetry are well within the limits of expected behavior for natural collapses. It isn't my fault that a whole collection of uninformed laypeople think they know better than the professionals.

When the answer is right, they don't have to say anything.
In fact, the 2 million architects and engineers that HAVEN'T joined this silly group is ample evidence of their support of the NIST findings.

Speed of collapse, is exactly how it should collapse, 911 truth can't do physics.
Symmetry, there was no symmetry; that is math, and 911 truth can't do math. The symmetry claim is super dumbed down, and it means nothing.
Byproducts of thermite? lol, you mean thermite, not by products. You don't understand, there was no iron found, that is a byproduct of thermite, zero found at the WTC. oops
What official cover-up? You offer no evidence.

You support lies about 911, there is no disagreement, you post lies.

That was the former excuse for "truther" nonsense. Some "truthers" that haven't kept up with "truther" BS still make that claim.

Now "truthers" make the exact opposite claim. Their "falling into its own footprint" claim was then transfered to the WTC7 collapse. You can't let that BS go to waste.

most likely, a combination of explosives and incendiaries were used to bring down these buildings.

There were zero sounds of explosives on 911, but then 911 truth can't have the truth.
13th year for lies from 911 truth showing a building falling with the energy of E=mgh released, and they have no clue each tower energy due to gravity was like 130 2,000 pound bombs. No clue 911 truth followers fall for insane lies of explosives because they don't understand simile.

No thermite damage to any steel on 911, not one failed cult member of thermite 911 truth can show evidence of thermite; the paper by Jones was a fake conclusion because Jones lied; Jones best work is work where Christ walked in the new world. Good luck with your lies.

Operation Northwoods was a series of proposals that originated within the Department of Defense and the Joint Chiefs of Staff of the United States government in 1962. The proposals, which called for the Central Intelligence Agency, or other operatives, to commit acts of terrorism in US cities and elsewhere, were rejected by the Kennedy administration.

If Bush and Cheney were in office in 1962 (instead of Kennedy)?

U.S. Military Wanted to Provoke War With Cuba
N E W Y O R K, May 1, 2001
By David Ruppe
In the early 1960s, America's top military leaders reportedly drafted plans to kill innocent people and commit acts of terrorism in U.S. cities to create public support for a war against Cuba.

Code named Operation Northwoods, the plans reportedly included the possible assassination of Cuban émigrés, sinking boats of Cuban refugees on the high seas, hijacking planes, blowing up a U.S. ship, and even orchestrating violent terrorism in U.S. cities...continued

http://abcnews.go.com/US/story?id=92662

Operation Northwoods proves that the US government, or at least certain high level elements within it, are capable of carrying out something like 911. All they needed was the right commander in chief to sign off on it.

You can't use Operations Northwoods for 911, UBL had no Joint Cheif of Staff - and UBL approved the murder of thousands.

You spread lies about 911, using plans not done as proof of your fantasy; but you have no evidence.

Where does it say kill, or murder anyone? I did see "Conduct funerals for mock-victims".

How does a plan not approved support your fantasy version of 911.

Looks like you and UBL think plans like this are good to do - Why do you apologize for the 19 terrorists by making up lies about 911


LOL, 911 truth logic takes a plan turned down, and use it support a plan the US government did in their fantasy version of 911. Now that is extra credit 911 truth super logic of woo

19 terrorists did 911 with 4 aircraft, they only hit 75 percent of their targets.
911 truth with no evidence has failed, hitting 0 percent of their targets.

19 terrorists is not a theory, it is a fact. Not like 911 truth's idiotic inside job CD thermite claptrap.

911 truth spreads lies, their only product; in the 13th year of failure.

The plot is too complex for the 911 truth followers who spread lies for 911 truth.

911 plot.
1. Take planes
2. Crash planes

Wow, that is too complex for most people to comprehend...

A 767/757 become deadly kinetic energy weapons when flying 470 to 590 mph. Each plane on 911 had impacts equal to 1300 to 2093 pounds of TNT. Like bullets with the energy of a 2,000 pound bomb.
Called steal your weapon of mass destruction - 19 terrorists used customs of how the US treats hijackings to fool the USA.
911 truth, called fraud, uses ignorance of its followers as a way to spread lies about the USA, apologize for terrorists, and like NAZIs, form a following of dumb down McVeigh like followers, chanting inside job.

911 truth lies about 911, and follower follow blindly, no clue there is no evidence for their claims.
