...and yes, i'm saying that well-placed intelligence and military individuals have told me that you can bring a building down, cleanly, within 8 hours, but that it would not be an inexpensive operation. When someone wants to demolish an old high rise brownstone to put up a shiny new stack of million dollar condo's, they want to spend as little as possible - different story.

8 hours for an unprepared (silent) demolition in a burning building at the site of the biggest ever terrorist attack...

Research it for yourself people.

9/11 Truth: The Mysterious Collapse of WTC Seven
Why NIST’s Final 9/11 Report is Unscientific and False

"...But WTC 7 had not been hit by a plane, so it was apparently the first steel-framed high-rise building in the known universe to have collapsed because of fire alone. New York Times writer James Glanz quoted a structural engineer as saying: “[W]ithin the structural engineering community, [WTC 7] is considered to be much more important to understand [than the Twin Towers],” because engineers had no answer to the question, “why did 7 come down?” [2]...

...According to the National Science Foundation, the major types of scientific fraud are fabrication, falsification, and plagiarism. There is no sign that NIST is guilty of plagiarism, but it is certainly guilty of fabrication, which can be defined as “making up results,” and falsification, which means either “changing or omitting data.” [13]

The omission of evidence by NIST is so massive, in fact, that I treat it as a distinct type of scientific fraud. As philosopher Alfred North Whitehead said in his 1925 book, Science and the Modern World: “It is easy enough to find a [self-consistent] theory . . . , provided that you are content to disregard half your evidence.” The “moral temper required for the pursuit of truth,” he added, includes “[a]n unflinching determination to take the whole evidence into account.” [14]...

NIST, however, seemed to manifest an unflinching determination to disregard half of the relevant evidence."..."

BBC REPORT ON EARLY WTC7 COLLAPSE ( by thedreadzone

the following is a decent collection of WTC7 footage:
www.youtube.com/embed/JnLcUxV1dPo

A particularly revealing shot is at the 11 minute 35 second mark where you see nice clear reflections in slow motion off of hundreds of windows on one side of the building which don't begin shattering until the vertical distance has already dropped by at least 35 percent. At the bottom when the window area turn black - that isn't from the building being in shadow - it's from the windows finally having shattered completely. Actually quite amazing. This building has a different internal structure than the main towers. The entire side of the building just sloughs off like a dirt slide after a heavy rain in southern California.. I'm not the scientist Dr. Jones is. I'm just saying I know him. My father was a prolific civil engineer - and THAT building was very well supported with heavy steel that doesn't just give up like powdery snow. No main structures taken out by the sheering force of a plane; no subsequent extended pressure from a massive unsupported area above the sheered off columns as with Towers 1 and 2.

Unlike with Towers 1 and 2, we can see the top of the building clearly through the fall. Those are massive steel structures just giving up like they suddenly became yogurt dropped from the same height.

You can at least agree that I'm drawing it from an entirely different angle, yes? We know the DOD, CIA and IRS were clients in the building. We know the WTC7 debris was first priority for large scale clearage. We know the vast majority of the rubble of WTC7 was moved and processed so quickly that it can't be traced.

If WTC7 was destroyed intentionally on the same day for national security purposes, it doesn't surprise me that they would hesitate to inform the public. Looking back on it now, perhaps they would admit they "should have".

In closing, my advice is...don't take that Electromagnetism Class from Dr. Jones...that final exam was hell...and i was going for B.A degree. What was I thinking???

Another question might be the following? If there were a conspiracy plot to destroy the World Trade Centers, why bother with a delayed attack on WTC 7? Would it have been to try to kill a bunch of first responders? If so, why not detonate before the building was left abandoned? Was it to increase the size of the catastrophe? The twin towers and the 3000+ dead, and the drama of it all was the catastrophe. Building 7 didn't really change the story at all. So why would anybody risk getting caught intentionally demolishing an extra building that didn't have a plane hit it? The whole thing is ridiculous. There isn't even a lack of motive. There is motive to not demolish WTC 7. The fact that it came down is evidence that the whole thing wasn't a conspiracy.

Now, I know that HerraclitusStudent is trying to frame the question in terms of looking at all of the odd things on one side of the coin without looking at all of the odd things on the other side of the coin. The idea being that he wants to establish that the official version is incorrect, and then go looking for some alt version. He/she is asking us to explain everything that seems intuitively odd about an extraordinary event to make us think that some other extraordinary event (giant conspiracy) happened without examining anything odd about the other extraordinary event. This is a perfect example of coming up with a theory and using every piece of evidence that looks to support your theory and ignoring every piece of evidence that makes it less likely.

Further, there are little factoids released to make something seem less likely, like WTC 7 was the only steel building in the universe to go down due to fire. This really seems unlikely, especially when we use the word Universe instead of world. What the fuck is that about - other than an obvious piece of rhetoric designed to bamboozle a complete rube? We don't even know if there are other life forms in our Universe, much less if they have steel buildings, or if one burned to the ground. If we get back to asking about steel buildings that have been destroyed due to fire, we don't have any other examples of building being left to burn for 8 hrs, either, do we? These facts without any analysis are useless.

Indiana Jones says

But WTC 7 had not been hit by a plane, so it was apparently the first steel-framed high-rise building in the known universe to have collapsed because of fire alone

That statement right there is reason enough to throw out anything that site says. Because it did NOT collapse because of fire alone. This is well documented, and not in doubt.
That statement is a pure lie mean to dupe folks.

The building was heavily damaged. To ignore this fact is ridiculous.

And all the conspiracy nuts arguments generally boil down to things not behaving as they BELIEVE they should. As if common sense should trump scientific analysis of a skyscraper that is hit by a fully fueled commercial jet. Or they know when and how someone should cry when reacting to a traumatic event.

The world if full of things that don't immediately make sense.

deepcgi says

THAT building was very well supported with heavy steel that doesn't just give up like powdery snow.

No it wasn't well supported by heavy steel. You don't know what you are talking about. It's a framed tube (also called hull and core) building same as 1 and 2, not a steel girder type building like empire state building. It has a light exterior framed shell and a central framed core with trusses running between. The exterior wall is the structure. There are no main structures. Compromise the outer shell and the whole structure is compromised.

Indiana Jones says

so it was apparently the first steel-framed high-rise building in the known universe to have collapsed because of fire alone

The WTC is the only framed tube building to have an uncontrolled fire.

Assuming the official version of WTC7 is wrong and not what happened, then we are already so deep into extraordinary territory that pretty much any extra fantasy explanation could be brought to fit the known facts. For example you get people like deepcgi: "we know the DOD, CIA and IRS were clients in the building" followed by whatever you can imagine. Reality, it's well known, is in fact often stranger than fiction. This is why I see it as meaningless to even try to argue about what *could* have happened in the absence of more solid information.

What is not speculation is this:
- a steel column doesn't suddenly disappear.
- a set of many steel columns don't suddenly surrender all resistance at the same instant by coincidence.
- a steel column doesn't crumble.
- a steel column can bend or break, but then it tends to push the mass it supports to the side, outside of its main resistance path.
- a steel column could be pulled down by other, but then again would fall to the side.

I don't have theories, I don't care about the factoids that are mentioned in the article. All I need is an even plausible explanation of how a line of steel columns suddenly stop all resistance and and starts free falling at the same instant vertically, without being pulled to the side. Because in the absence of that, only extraordinary explanations remain.
It's just pathetic that no one is presenting such an explanation. (and NIST arguments are convoluted and don't fit the evidence well).

curious2 says

That is like claiming, without math, that an avalanche should be slowed by the trees in its path. Do the exponential calculations and show your work instead of pretending to be smarter than NIST.

This is a bit disingenuous because the article I mentioned cites different calculations and discusses them. It is a small physicists publication so I'm willing to believe that the editors actually looked at it and made sure it sort of made sense before damaging their credibility on a theory of that kind.

"Researchers have since
provided calculations showing that a natural collapse over
one story would not only decelerate, but would actually
arrest after one or two stories of fall"

You also assume that the entire upper mass would suddenly fall 1 floor. It wouldn't, or not at least not on all sides of the building simultaneously. And there is no exponential calculation involved. The energy equation you quote is also equal to the potential energy which is linear of the mass and distance covered.

But nonetheless. Maybe columns had a particular vulnerability that is non-obvious. At least the train of thoughts is "sort of" plausible. And therefore let me concede it is in fact the most likely.

There is no such explanations for WTC7. Your argument about damage is fine, except there is no damage to the 2 sides of the building observed. Even assuming there was damage we can't see, it still doesn't explain how asymmetrical damage can result in a symmetric fall of a large part of the building.

No one is saying any of those things. The building appeared to my naked eye to collapse at about a constant velocity, which is very different from constant acceleration. It also dropped in an asymmetric manner, leaning to one side as it fell. There are many things holding a building together, and these would cause it to collapse at once by overloading other parts of the building suddenly when one part fails. All of this is speculation rather than a proper analysis, but it is enough to discredit the non-analytic speculation on the other side of the argument.

No this is not speculation. Some people spent a tremendous amount of time and energy to map the acceleration of the building frame by frame.

The building suddenly started falling with constant acceleration of gravity.

Further even the NIST now acknowledges free fall: "Stage 2 (1.75 to 4.0 seconds): gravitational acceleration (free fall)"

https://www.nist.gov/engineering-laboratory/faqs-nist-wtc-7-investigation

What it actually says in context:

In the draft WTC 7 report (released Aug. 21, 2008; available at http://www.nist.gov/el/disasterstudies/wtc/wtc_draftreports.cfm), NIST stated that the north face of the building descended 18 stories (the portion of the collapse visible in the video) in 5.4 seconds, based on video analysis of the building collapse. This time period is 40 percent longer than the 3.9 seconds this process would have taken if the north face of the building had descended solely under free fall conditions.
.........
The analyses of the video (both the estimation of the instant the roofline began to descend and the calculated velocity and acceleration of a point on the roofline) revealed three distinct stages characterizing the 5.4 seconds of collapse:
Stage 1 (0 to 1.75 seconds): acceleration less than that of gravity (i.e., slower than free fall).
Stage 2 (1.75 to 4.0 seconds): gravitational acceleration (free fall)
Stage 3 (4.0 to 5.4 seconds): decreased acceleration, again less than that of gravity
This analysis showed that the 40 percent longer descent time—compared to the 3.9 second free fall time—was due primarily to Stage 1, which corresponded to the buckling of the exterior columns in the lower stories of the north face. During Stage 2, the north face descended essentially in free fall, indicating negligible support from the structure below. This is consistent with the structural analysis model, which showed the exterior columns buckling and losing their capacity to support the loads from the structure above. In Stage 3, the acceleration decreased as the upper portion of the north face encountered increased resistance from the collapsed structure and the debris pile below.

Rashomon says

which showed the exterior columns buckling and losing their capacity to support the loads from the structure above

Except
- the videos shows sudden acceleration to free fall (see the graph above)
- "buckling", by definition: "bend and give way under pressure or strain", means there is no free fall.
- no buckling is seen on the videos

But anyway... If someone is hard bent on believing something in spite of the evidence, no amount of arguments will change their minds.

So are we back to not believing that 2 planes hijacked by Islamic terrorists were purposely flown into the towers?

Let's start by agreeing on what is undisputed, then we can try to move forward on this.

1. Does anyone think that 2 planes weren't flown into the twin towers by Al Qaeda?
2. Does anyone think that the reason the towers fell wasn't because of the impact of the planes followed by the fire?

Once we have those questions answered, we can talk about WTC7 again, if you'd like.

I just answered Strategist note that "I don't see the Mid East Arabs, Iranians, China, N Korea, or anyone accept anything beyond the official version.". They don't.
For the record, I absolutely believe 4 planes were hijacked by Islamic terrorists and 3 flown into buildings.

Here is a paper which goes into a theory of "why" the WTC buildings were brought down. It gives background of possible motivation for an "inside job".

Collateral Damage U.S. Covert Operations and the Terrorist Attacks on September 11 2001

On September 11, 2001 the definition of National Security changed for most U.S. citizens. For an entire post war generation, “National Security” meant protection from nuclear attack. On that day, Americans redefined that threat. On September 11, 2001 three hijacked airliners hit three separate buildings with such precision and skill that many observers believe those flights were controlled by something other than the poorly trained hijackers in the cockpits.This report contends that not only were the buildings targets, but that specific offices within each building were the designated targets. These offices unknowingly held information which if exposed, subsequently would expose a national security secret of unimaginable magnitude. Protecting that secret was the motivation for the September 11th attacks. This report is about that national security secret: its origins and impact. The intent of the report is to provide a context for understanding the events of September 11th rather than to define exactly what happened that day.

Tampajoe says

Your assumptions regarding other peoples knowledge of physics are at least consistent with your assumptions regarding how a building would fall. The video evidence that you provided with the high school physics teacher showed the following:
1st second: Very slow fall, mostly at constant velocity once moving.
Next 2 seconds: Near free fall
4th second: Continues accelerating, but much slower than free fall
5th second: Constant velocity

There is nothing about this that contradicts physics. The outer shell is composed of vertical steel beams. If these reached a temperature near melting, they could shear, so that suddenly there was no support under the top length of beam. Whatever masonry and glass was in place would offer near zero resistance. So, what about the other beams? If they were near melting point, then the extra weight from the first column shearing could have caused them to shear within a second of the first. If they are composed of sections with mechanical connections, it's possible that those sheared due to torque when the first column went. The fact is that this is all rampant speculation from someone who hasn't explained why it wouldn't happen that way. The only thing that is clear from his analysis, is that all of the beams would have had to shear within a second or so of each other. Based on the 2 second free fall, the shear point would have to be at least 60 feet from the ground and more than 60 feet from the top. The 60 feet comes from 2 seconds of free fall, and the number would be a bit higher, b/c it was already moving when the freefall started. Anyway, 60 feet is pretty small compared to the size of the building, which was 700 feet tall. So, this wasn't a very long period of free fall.

Hater says

Steel framed buildings have burned hotter and longer but never fell.

Do you have data on how hot and long the fires burned? If so, I missed that.

YesYNot says

There is nothing about this that contradicts physics.

I repeat again:
1 - asymmetric damage (fire, debris) cannot result in a symmetric fall.
2 - if any of these columns were "buckling" under the weight, by definition that part of the building could not go into free fall. It would give way more slowly. None of the columns of the outer shell offered *any* resistance at all. They just completely gave way at the same instant.

If you don't find this bizarre, then there is no point discussing this.

Btw, 1 second difference between the fall of 2 sides would mean a 15m difference vertically after 2 seconds of free fall. The entire facade would have been torn into pieces instead of falling almost as 1 block.

Maybe we should begin by proving something more fundamental. Assume for a moment that I'm not joking.

Let's create a NEW conspiracy. Not a false one, something real. Something substantial. It won't even matter if people find this blog with my suggestion of the very thing, because the wise, intelligent, educated, modern agnostic never believes in them. Conspiracies are for nutcases.

The key is that the conspiracy be sufficiently complex as to defy the initial level of scrutiny. It also needs to feed nicely into an initial story that media can run with in a matter of hours - a day or two at the most. That story can give all the appearances of being vast and complex, but has to remain plausible to a modern grounded intellectual.

The beauty of it is that we make it epic in scale. I would say we should create over-complications by simply giving all of the co-conspirators some nonsensical first commandment which must never be broken. Like: during the execution of our conspiracy, all conspirators must, at 4:00 pm, no matter how dire and deadly and vital the circumstances may be, stop and have a spot of tea. With a smile. Mango Tea.

NBC News Opinion: "Ridiculous. You are telling me that right in the middle of this gargantuan crime conspiracy with the world crumbling around them, these conspirators just stopped at Starbucks and ordered Mango Iced Tea? And sat there for ten minutes while every single second counted, talking about real estate prices? Preposterous. They stopped because they were thirsty and not some harried conspirators who were in the middle of some huge operation".

Then, I would create disinformation and false trails. I'm not recommending these things to be flippant. I'm saying it's critical, because few conspiracies ever work. A third requirement would be to plant an intentional nutcase theorist to propose that the very thing we are doing is a conspiracy.

Sound too silly for such serious conspiratorial talk? Exactly.

Just call me Armen.

Heraclitusstudent says

1 - asymmetric damage (fire, debris) cannot result in a symmetric fall.

Not strictly true. But there would have to be a situation where over the 8 hrs or so the building burned, the heat within the building was fairly uniform on the floor(s) where the failures occurred.

Heraclitusstudent says

if any of these columns were "buckling" under the weight, by definition that part of the building could not go into free fall. It would give way more slowly. None of the columns of the outer shell offered *any* resistance at all. They just completely gave way at the same instant.

For the first second, there was no free fall. All of the buckling or shearing would have to have happened during that time. You say it should happen way more slowly, but you haven't explained how much more slowly and why. Again, they gave way within a second of each other, not at the same instant, and with each failure, there was instantly more force on each of the remaining support beams. That force was probably no longer straight down, so it would be more likely to shear the beams, which requires a side force.

Heraclitusstudent says

If you don't find this bizarre, then there is no point discussing this.

I find it odd, but there are a lot of surprising things in science that only seem obvious once you have the mechanism explained to you. One example would be a plane flying with Bernoulli's principle. The same concept can explain why a train speeding through a narrow tunnel can have the windows blow out outward instead of inward.

The huge missing piece of information in WTC7 is how hot it got and why. I didn't read the report, so I don't know if there was any speculation on that. Here's some video though: http://www.dailymail.co.uk/news/article-2056088/Footage-kills-conspiracy-theories-Rare-footage-shows-WTC-7-consumed-fire.html

Heraclitusstudent says

1 - asymmetric damage (fire, debris) cannot result in a symmetric fall.

A couple things wrong with this statement. 1--the fall wasn't perfectly symmetrical. 2. How are you measuring the symmetry of the damage? Do you have some calculations showing the amount of damage sustained at each quadrant of the building? And have you calculated/modeled how that damage should have manifested itself in the fall?

No? Then your opinion is worth less than that of the commission.

Heraclitusstudent says

if any of these columns were "buckling" under the weight, by definition that part of the building could not go into free fall. It would give way more slowly. None of the columns of the outer shell offered *any* resistance at all. They just completely gave way at the same instant.

And the building wasn't in free fall for the entire collapse. As you have been told multiple times.

YesYNot says

the heat within the building was fairly uniform on the floor(s) where the failures occurred.

The reason why fires typically don't destroy steel frame building is that (1) burning office furniture and carpets doesn't provide much heat and that (2) these materials burn relatively fast and then the fire stops/moves before the columns have the time to heat sufficiently to weaken them, (3) the redundancy of the columns means weakening 1 or 2 is not enough.
So to imagine that one column was sufficiently weakened, you would need to have a strong fire raging for a long time at the same place near the column. To weaken all column you would need to have a raging fire burning throughout the building and not stopping or moving for a long time. Even the article you posted shows *local* fires that apparently have moved up to a different floor.
So talking of heat: uniform throughout one floor, long lasting enough, and strong enough to weaken steel (probably 800-1000 deg C) doesn't make a lot of sense.

YesYNot says

For the first second, there was no free fall. All of the buckling or shearing would have to have happened during that time.

Buckling means they started falling. This is not what is seen. They almost didn't move (as we see the center of the building collapsing), then suddenly went into free fall.

YesYNot says

there are a lot of surprising things in science that only seem obvious once you have the mechanism explained to you.

Fair enough. But there are basic behaviors like columns not disappearing on which you can generally count. So very suspect.

I would add for context that the same people that were in charge (i.e. Bush & co) displayed almost constant dishonesty and willingness to manipulate the public.
For example they blatantly lied to use 911 as a pretext to start a war with an unrelated country.
Compared to starting a war, I would say lying about a building doesn't seem very consequential in any case.

Tampajoe says

1--the fall wasn't perfectly symmetrical. 2. How are you measuring the symmetry of the damage?

(1) is a ridiculous statement, (2) a ridiculous question. You can see 3 corners of the building coming down within a fraction of a second, and the entire frame going down as one block.
To contrast with fires, local on all pictures I have seen. Damage from debris would obviously have been local as well.

Tampajoe says

the building wasn't in free fall for the entire collapse.

It was basically in free fall for 3 seconds or a 45m fall. I think a set of steel columns opposing no resistance for 45m is fairly relevant.

Gary's still around. Here's a great piece from Gary about Driverless Cars being a Zionist Conspiracy.
