Explosives don't melt steel, they only vaporize it.
If you look at the article you will see that the words are actually those of the author James Glanz. He is paraphrasing Barnett, not quoting.Not exactly someone who would make a casual mistake on such things, don't you think?
Don’t be ridiculous.Furthermore, if Dr. Barnett made a mistake after having had his statement on evaporated steel published in the New York Times, don't you think it'd make sense to have made a retraction? And yet, I have seen no such thing occur.
Utter stupidity. As he was not even quoted saying it we can't be sure that even said those words.Surely you agree that there should be an investigation as to why his finding was not included in the report?
Explosives don't melt steel, they only vaporize it.
You have a small problem of evidence….I'm simply stating NIST's conclusion in its 2004 report titled
Federal Building and Fire Safety Investigation of the World Trade Center Disaster Project #3: Analysis of Structural Steel Update:
http://wtc.nist.gov/media/P3MechanicalandMetAnalysisofSteel.pdf
At present, I -personally- still believe that the steel became molten and some probably evaporated, as Dr. Barnett stated.
NIST believe that the temperature did reach those numbers. As established, unprotected steel will reach temperatures marginally lower than that of the atmosphere.Since the aforementioned 2004 report, I agree that NIST has updated their assessment of how high the temperature of steel could have gotten, although they never state that the -steel- could have reached 1000C; only that the air temperature could have reached it for 15 to 20 minutes.
Why not? There is ample evidence that they can and did reach temperatures that high. The Cardington tests had temperatures reaching 1000C. This has been pointed out to you about a dozen times.It matters because if the jet fuel and/or office fires couldn't have done it,
Only if you wish to leave reality and ignore all the evidence you don’t like.it must have been caused by something else, such as explosives.
The thousands of liters of jet fuel initiated a massive office fire over many floors. Eventually the fuel was burnt out but the fires were roaring by that stage. To then state that the jet fuel didn’t cause the high temperatures is a stupid attempt to misrepresent the truth. Only the very stupid or gullible would fall for that.Even Kenny thinks it would have taken 40 minutes for 1000C air temperature to translate into 900C steel.
In terms of the official story, it gave up on such temperatures being induced by jet fuel fires a while back.
No that was not the point. Re-read it. They are claiming that the steel was totally obliterated during the collapse. This is completely wrong.Where does the claim say that the steel core didn't survive a few moments after the collapse? The point is it was completely destroyed at amazing speed.

Here is the quote from the more recent NCSTAR1-5F
The simulations and the visual evidence suggested that the duration of temperatures in the neighborhood of 1,000 oC at any given location on any given floor was about 15 min to 20 min. The rest of the time, temperatures were predicted to have been in the range of 400 oC to 800 oC on floors with active fires.
Steel is down to 50% of its strength at around 590C.

No evaporated steel was found.
Though I'm not sure how you would even identify something that has been evaporated.
All the credible evidence points to the temperatures being not much over 1000C.

The evidence you have presented so far doesn’t stand up to any scrutiny. This is something you don’t want to see.
Once again, explosives explode. They shatter and break things with force. They don’t just heat up steel.
Exactly:
[personal attack edited out]. We were discussing the cause of that collapse. That is a photo of the building after the collapse had started.
That is what it looks like when one of the tallest buildings in the world collapses from the top down.

That is beside the point. The conspiracy theorists claim it is a controlled demolition because they say it looked like a controlled demolition. It didn't look like a controlled demolition at all.
You are just altering the argument by then saying 'oh bit it's possible'.
Originally Posted by scott3xIf you take a look at the debris, you'll notice that a lot if not most of the upper debris had the texture of dust or at best sand...
Are you serious? Look at the footage. That top part of the building held together for at least some of the collapse. Just because you can see concrete breaking up that doesn’t mean its just a bit of sand and doesn't weigh anything.

A bucket of sand will yes but the top thirty floors of WTC2 were not sand.

What happens to the block and its angular momentum?
We observe that approximately 34 upper floors begin to rotate as a block, to the south and east. They begin to topple over, as favored by the Second Law of Thermodynamics. The torque due to gravity on this block is enormous, as is its angular momentum. But then — and this I’m still puzzling over — this block turned mostly to powder in mid-air! How can we understand this strange behavior, without explosives? Remarkable, amazing — and demanding scrutiny since the US government-funded reports failed to analyze this phenomenon. But, of course, the Final NIST 9-11 report “does not actually include the structural behavior of the tower after the conditions for collapse initiation were reached.” (NIST, 2005, p. 80, fn. 1; emphasis added.)

So explosives soften steel, melt steel, cut steel, evaporate steel, keep it molten for weeks, explode in the basement causing a collapse at the top
can knock over lamp posts
and they turn concrete to dust while it is collapsing.
Is there anything explosives can’t do?
As has been demonstrated to you, the temperature of the steel will be only marginally below that of the atmosphere.Fine. The above quote from NCSTAR-1F seems to essentially be saying the same thing as before- that the maximum air temperature was 1000C for 15 to 20 minutes. The steel certainly wasn't mentioned.
Your question was a pointless one.I'm not so sure of that, but you didn't answer my question.
Why don’t you think about it.You'd have to ask Dr. Barnett.
The problems with that molten metal page have been pointed out to you numerous times. Your faith in your conspiracy religion prevents you from seeing reason.I definitely disagree with you there:
http://www.sciforums.com/showpost.php?p=2082459&postcount=2203
Nope. I went looking for corroborating evidence and instead what I found was the report by his team that estimated temperatures near 1000C. The very article has the headline explaining that they found the cause of the collapse and it wasn’t bombs. Looking at the article you can see that he isn’t even being quoted saying those words, it is a paraphrase. I have done some work to asses the validity of the claim while you have just ignored the bits you don’t like and clung desperately to the conspiracy that you just know has to be real whatever the evidence illustrates.I, on the other hand, would argue that you are the one who doesn't want to ponder anything that might disagree with the official story, such as Dr. Barnett's comment on evaporated steel.
If you want to make a case of my comment I encourage you to do so. I have been very, very patient with you Scott and I think a moderator will see that if they read from the start. Meanwhile although you do not make personal attacks, your behavior borders on intellectual dishonesty and trolling.1- Quit making personal attacks.
No your response was a stupid one. You have posted a photo of a building halfway through a collapse, you think it looks like a building exploding so you think explosives caused the collapse. If you watch the video and not just look at a still photo it is clear that the building is not exploding it is collapsing.2- Based on your previous statement, I believe my response made sense.
High powered explosives to not warm up and soften steel.With the help of some high powered explosives, I'd agree.
Pointless drivel. Others and myself have explained why that comment is meaningless numerous times.Fire alone has never brought down a steel-frame high-rise before or since.
Those points have all been debunked and are complete and utter idiocy.I have already listed a bunch of points from the A&E web site that make it clear that it was a controlled demolition.
No they were characteristics unlike a controlled demolition. This is the problem with your religion and trying to fit evidence to the conclusion already reached. Can you not see what you are saying here? They are trying to point to characteristics like a CD. The characteristics that are very much unlike a CD you just say “well they are evidence as well… evidence of an unusual CD! ” .The fact that it also had some unusual characteristics for a controlled demolition
Its an absurd theory with no credible evidence to support it.doesn't change the fact that it's still the best theory to explain what happened.
The top thirty floors of WTC2 were not mostly dust and did weigh quite a lot.All matter weighs -something-. Spread out dust, however, doesn't weigh all that much per cubic meter.
Complete nonsense. The top thirty floors are falling downwards. It is clear that they are falling, not exploding.And breaking up is putting it mildly; I think exploding outwards covers it better.
I thought you and your ae911 buddies said it collapsed into it’s own footprint? Make your mind up.There's also the issue that much of the WTC towers' debris fell outside of their footprints;
So because there was some ejected debris you therefore claim that the top thirty floors exerted no downward force at all. Right? You want to think about that one? Are you capable of recognizing how stupid that is?all that debris simply couldn't have aided in the hopelessly flawed pancake collapse theory, because it wasn't even falling down on the rest of the building.
Of course there was dust outside the footprint. Watch the video. The dust was spread out during the collapse and then fell several hundred meters to the ground. It’s not going to be sucked back into the square footprint. ?True. However, a lot of the steel was ejected outside of the WTC2 footprint and the concrete was pulverized into fine dust, much of which -also- was ejected outside of the WTC2 footprint.
All you have done is apply the same flawed reasoning.If you want a technical argument as to why the pancake theory is hopelessly flawed, you may want to attempt to understand an article from Gordon Ross, who holds degrees in both Mechanical and Manufacturing Engineering:
http://gordonssite.tripod.com/id1.html
I personally don't understand it,but I've seen other arguments regarding the conservation of momentum that are certainly simpler, such as physicist Steven Jones' argument:
**********************************
The rapid fall of the Towers and WTC7 has been analyzed by several engineers/scientists (http://911research.wtc7.net/wtc/analysis/proofs/speed.html; Griffin, 2004, chapter 2). The roof of WTC 7 (students and I are observing the southwest corner) falls to earth in less than 6.6 seconds, while an object dropped from the roof would hit the ground in 6.0 seconds. This follows from t = (2H/g)1/2. Likewise, the Towers fall very rapidly to the ground, with the upper part falling nearly as rapidly as ejected debris which provide free-fall references (http://911research.wtc7.net/wtc/analysis/proofs/speed.html; Griffin, 2004, chapter 2). Where is the delay that must be expected due to conservation of momentum — one of the foundational Laws of Physics? That is, as upper-falling floors strike lower floors — and intact steel support columns — the fall must be significantly impeded by the impacted mass. If the central support columns remained standing, then the effective resistive mass would be less, but this is not the case — somehow the enormous support columns failed/disintegrated along with the falling floor pans.
How do the upper floors fall so quickly, then, and still conserve momentum in the collapsing buildings? The contradiction is ignored by FEMA, NIST and 9-11 Commission reports where conservation of momentum and the fall times were not analyzed. The paradox is easily resolved by the explosive demolition hypothesis, whereby explosives quickly remove lower-floor material including steel support columns and allow near free-fall-speed collapses (Harris, 2000).

The above mentioned behaviour shows no such thing; it only shows that a part of the WTC tower didn't have sufficient explosives to get it to yield at a certain point quickly enough; thus, the partial toppling that was arrested by the top part of the structure simply disintegrating in mid air (yet more evidence of explosives being used).
That seemed to what you were saying. Perhaps you were saying there were explosions in the basement that had no effect at all. Either way it is a stupid theory.Who said that the explosions in the basement caused the collapse at the top?
Or a plane knocking them over…. like the many witnesses confirmed.Not sure if the lamp posts were cut using explosives, thermite, or simply something else.
Yep...
And the iron alumino spheres found on the roofs of neighbouring skyscrapers? And the alumino-iron spheres found within ONE HOUR of the collapses? And the molten material seen pouring out of the tower seconds before the collapse?Search and Rescue teams often use Cutting torches to remove beams that the "Jaws of Life" weren't designed to cut through. It would explain "Melting".
Nanothermite is both explosive and a chemical incendary.Explosives don't melt steel, they only vaporize it.

It would be so much easier to get a hold of commercial-grade demolition charges, tools made for the job, than it would be to design a system that would allow thermite or the likes to cut horizontally.
