For the collapse of a 47 storey skyscraper, the debris pile was incredibly neat. And no, it did not slam into the Verizon building. Some relatively small parts hit it but that's to be expected when steel dropped from great height hits the ground so close to other buildings (Verizon, Post Office and Fiterman Hall).
Can you answer the question I asked Edx an hour ago? |

You didn't read the NIST report for comprehension, and didn't read the CTBUH critique of the draft report for comprehension.
CBTUH identified an internal consistency in the NIST report: NIST describes and models plausibly how the floors and their connection to column 79 failed first, making 79 excessively slender, and causing it to buckle subsequently. Therefore, the one statement in the summary that the failure of 79 was the cause of collapse is misleading. CBTUH wished that this discrepancy be resolved. If you read the whole NIST report for comprehension, you will find that NIST does not really connsider the failure of 79 to be the start of all trouble; its a slip. Nothing more. Your elaborate attempts to ignore MOST of what CBTUH wrote is a shining testimony to your dishonesty. |

Why on earth should they explain something that did not happen?
And even if it did happen (it didn't - nothing was symmetric about that collapse), why should CBTUH explain it? It is totally irrelevant. So? They fully agree that WTC7 collapses due to intense, unfought fires, and they most strongly disagree with everything you, as a truther, believe in. |

WRONG.
NIST actually says on pages 623 and 624 of NCSTAR 1-9 (I paraphrase):
WRONG. CBTUH in fact says:

Incredibly neat?
How do you know this? What are you comparing it too? I guess we all missed the dozens of examples of other 47 story skyscrapers that have collapsed in a "neat" pile that you are using as comparison....oh wait..... ![]() Your comment is really stupid.....try not to say dumb things in the future.....that will make reading your posts much less painful. |

That's funny: When the CBTUH guys say something which you believe supports your position, they are sane and intelligent. As soon as you realize they do not in fact support you but call you nuts, you switch your position and call them brainwashed.
What a disingenious little man you are! |

As Danny Jowenko said it doesn't pay for organisations to cross the government on matters 9/11. The management of CBTUH is well aware of that fact. I don't think they really enjoyed having all these building code changes foisted on them either as they make pretty clear in their pdf.

"Neat" is not an objective engineering term.
When buildings are CDed, their "neat" debris piles are aimed at areas with no other buildings on them. When the aim is to collapse "onto the footprint", not even adjacent streets are touched by more than dust. WTC7 caused the TOTAL destruction of Fiterman Hall (it was damaged beyond repair and had to be deconstructed) and added substantially to the more than US$ 1 billion of damages to the Verizon Building. Nothing "neat" about that. Which question? This: "Now, are you going to do what no other debunker has been capable of doing and tell me how the building fell as a single unit, straight down, with no initial rotation when, according to NIST, collapse started close to one corner?" No, I can't answer that question. We can't explain to you how something happened when that something didn't happen. Several FALSE premises in the question:
By the time collapse progression reached the periphery, all internal structural integrity was lost. When the first north and/or west face columns started to buckle out of sight, load reditribution happened at the speed of sound in steel and caused the remaining unbraced columns in that peripheral assembly to buckle in very rapid succession (fraction of a second). |

Incorrect.
He is superficially right about what NIST said: NIST is inconsistent and somewhat confusing about this "coluimn 79" thing: In their summary, it does indeed sound like column failure was first; but again, if you read the whole context, indeed the whole report, for comprehension, it becomes clear that NIST does NOT think column failure was the ultimate cause of collapse, but rather NIST is clear that several steps of floor failure lead to the first column failure. So he was substantially WRONG about what NIST said. He is TOTALLY WRONG about what CTBUH said: CBUTH did NOT AT ALL say that the collapse stared with multiple column failures. In fact, CBTUH stressed that collapse did NOT begin with column failure at all, but rather that it was floor failure that started the mess. They explicitly corrected the false impression given by NIST in their sloppy summary statement about column 79! mrkinnies' rendering of what CTBUH said is in fact the exact opposite of what they really said! You can't get any wronger than that! So yes, it was very very VERY wrong! Marokkaan; Why are you participating in this debate if you can see nothing at all that is of substance? You get everything so very wrong - you surely have not understood the NIST reports, and you definetely have not understood the CTBUH critique thereof at all. |

Its about the importance of the columns, you dont understand the principle.
No it was not very wrong, you have a problem with understanding reading. He never said wtc 7 BEGINS WITH And he never said wtc 7 STARTED WITH multiple columns And why you dont understand, the columns are the cause of the collapse, if nothing happened with the columns, then a total collapse of the building is impossible. By the way, why you are ignoring the debate in the other thread? Where you can see you made a lot of mistakes. And i will ask you again, why are you debating about this subject while you dont have the expertise? |

I'd like to ask you the same question, Marokkaan. You've posted in several threads and after being asked a number of questions, you disappear, possibly reappearing a day or two later and act like the questions don't exist.
Why is that? Could you please come back to one of the other threads and answer the questions I and others have repeatedly posed to you? |

Oystein, clearly you have to agree that NIST says column 79 failed because that's what they say....and yes, they say it was due to floor expansion.
Silly me for ommitting the latter explanation when I referred to NIST but you can stop jumping up and down about it now. Just for you.... NIST says floor expansion caused a failure in one internal column which led to collapse. CTBUH says floor expansion caused a loss of lateral restraint which led to the failure of multiple internal columns which led to collapse. Still an enormous difference and proves your beloved engineers don't quite agree with one another, especially when you read the list of issues CTBUH has with the NIST hypothesis and NIST's understanding of the fire and its role in causing column 79 to fail. And neither hypothesis can account for what the external columns were doing which is mightily problematic since these supported the facades. |

This is truly shocking. I hadn't realised the the CBTUH had so radically disagreed with NIST. How come there hasn't been an outcry to have such an august body as the CBTUH disgreee with NIST on their key collapse precursor ? The scenario that their entire collapse model is based on.
NIST say that they will not release their test data for independent verification because that might endanger the public safety but this completely changes everything. NIST was already disagreed with by technical professionals on many sides in their explantion of the collapse but to have the CBTUH express doubts as to the validity of NIST's explantion is the final straw. NIST should be compelled to release the data at once in the public interest and our continued safety. This clear doubt on such an important matter of public safety certainly cannot be allowed to stand. |

I'll explain, even though you won't understand:
What matters is if some claim or argument is correct, or true. In principle, everybody, regardless of education and expertise, can investigate questions and come to factually true conclusions. That is not what you are about when you make arguments from authority: When you construct an argument around the claim that someone else said this and this, and you want me to believe that other person, without presenting their actual arguments, that's an "argument from authority". This is valid if the other person is indeed an authority: - Has the relevant credentials - Is sufficiently and correctly informed about the subject matter. So, for example, referring to the NIST reports and saying "I believe X because these experts say so", is not bad, because - All the NIST guys have great relevant credentials - They have worked on a lot of correct data When you say, on the other hand, that I believe X, because 400 "professors" or "1500 architects and engineers" say so", than that's an argument from FALSE authority: - Most of these people do not have the relevant expertise - Most of the people are falsely or insufficiently informed about the subject matter Both points can be easily shown by randomly picking some guys from those lists. Now, when I make arguments here, they are never of the form "I believe X, and so should you, because I say so". I am not an authority. Don't believe me just because I say it. Judge my conclusions by the truth value of my premises and the validity of my reasoning and logic. |

Yes. If you add "collapse of several floors".
Yes. With 79 being the first to buckle. No! The way you phrased it now, there is no difference at all! It's just a matter of detail and focus, but we - NIST, CTBUH, you, I - agree now on the following sequence:
No, CTBUH does not at all disagree with NISTs finding that fires around column 79 and the 13th floor were responsible for global collapse by making floors fail. Do you acknowledge that? If so, I would ask you to repeat that in your own words! WRONG. Both NIST and CTBUH understand very well that progressive collapse of the building core doomed the rest of the building to very rapid demise. On that, CTBUH very strongly supports NIST and very explicitly condemns your stance (CD of some kind) into the domain of bad, ugly, unwanted fairy tales. |

How absurdly wrong you are, Bill.
I know you're trolling, but anyway. Let me educate you: Every structural and fire protection engineer knows, of course, that fire is a hazard to steel constructions. Why else would they spray fireproofing in steel, huh? Can you explain that? It is obvious that failure of steel members can lead to collapse. The Kader toy factory is the usual example for this: A low.rise steel frame building that collapsed completely due to fire (and gravity). Can you please acknowledge, Bill, that you are informed now that low-rise steel buildings can collapse completel due to fire? If so, please repeat that in your own words! Now - what if you build a low-rise building, only a lot higher? Is there some strange law that prevents steel structures from failing once they exceed, say, 30 meters, or 10 floors, or wherever "hi-rise" begins in your book? If so, then please explain! If not, then please think about this for a second: If low-rise buildings can collapse from fires, so can hi-rise buildings. In fact, it is much harder to construct hi-rise buildings than low-rise buildings such that they don't collapse. Now on to my engineering friends - here is a little true story I have told a few times already: One friend, who was also my neighbour at the time, and I had a chance to climb into the spire of our church tower, which is pretty high as churches go, something like 87m, IIRC. More than 80 at any rate. The tower is traditional brickwork up to maybe 55m, on top of that is a copper-clad helmet, which has had a steel-frame since the late 19th century. You climb up inside the helmet on open stairs that allow you to see the naked structure. My friend, who is a structural engineer, noticed quickly that several of the long steel elements were naked, with no fire protection on them. This, he explained, is a major hazard: Steel like that is prone to heat up VERY quickly to a point where their strength decreases below actual loads. He said that he's expect our church's tower cap to collapse complely within 15 or 20 minutes in case of an ordinary fire inside the tower. He went to explain that even old traditional wood beams would last considerably longer than that. And he explained to me that this is why the World Trade Center towers collapsed they way they did: Because no structural steel can survive intense fires for very long, unless the fire is speedily fought, and fire protection intact. Of course we know that the fire protection in the towers was NOT intact, and that the fires were not fought. My structural engineering friend knew very well, that WTC were fire-induced collapses, and that was far from a mystery or surprise to him. Quite the opposite is true: It is what any structural engineer worth his title finds obvious, expected and natural. |

What a load of rubbish you talk Oystein. Your engineering friends do not know that fire can bring down a steel framed hi-rise building- period. No steel framed hi-rise buildimg has ever collapsed from fire in the recorded history of the universe despite having much larger, hotter and vastly more long lasting fires, You are being transparently devious as I noted earlier.

They don't radically disagree at all. Both say floors collapsed leaving column unsupported so they buckled. NIST specified a specific column where they think it started, CBTUH did not. All they disagreed on was the exact mechanism involved in the failure of the floor to column attachments. Given that NIST spent much more time and effort on the problem I'd go with their version but it doesn't really matter either way as regards to the reason why 7 failed. Both agree it was fire.

NIST clearly states that the probable collapse sequence started with the girder supported by column 79 ''walking-off that column due to thermal expansion. This led floors 13 down to 5 to collapse causing column 79 to buckle, blah de blah de blah.
CTBUH disagrees with NIST that the buckling of column 79 and only that column was to blame citing instead a loss of lateral restraint and buckling of internal columns. But still, CTBUH, NIST or any debunkers including Chris Mohr and yourself have not been able to explain how all the exterior columns would buckle simultaneously just because the internal structure is collapsing. For NIST to say it just happened is pure folly because what they are saying is the internal columns and beams where weak enough to fall to pieces inside the building but strong enough to stay attached to the outer walls to maintain the loading on these walls in equal distribution. Even more foolish is their assertion that a collapse which started close to the north eastern corner could possibly drag all the contents and outer walls of the steel framing down on the opposite corner (approx 200-250 feet away) at the very same moment in time. It's laughable and is like reading a script from a 'B' movie. And you believe this crap! |

What previous fire was in exactly the same kind of building and was unfought?
The fires in WTC1,2 and 7 were in unique buildings and uniquely were not fought. Every steel framed hi-rise building has always collapsed from unfought fire in the recorded history of the universe |

I was wondering how long it would before the shill accusation was made. I find it strange that truthers are so sure there is an army of paid shills out there yet cannot actually show who is employing them or where. I wish they would find out and let me know. I could use the money!
