Invitation to Derek Johnson to discuss his ideas

Yes, hopefully he will respond and clarify his statement.

This firefighter (and the one behind him agreeing) didn't really mean molten steel running down the channel rails. They really meant something else, right?

Agree to what? I hear this as they agree that claims of "rivers " that they were told about are silly.

For Dog's sake, listen to what he says. Transcribe the words yourself. He doesn't say "I saw" and some people think he is expressing skepticism. Doesn't it strike you as strange that someone cut off the preamble?
This worker didn't really guess that it was 1500 degrees or that it was red hot almost six weeks later. He really meant something else, right?

Any trash fire can get to 1500DegF. So what?

And this guy is lying through his teeth, right?

http://www.youtube.com/watch?v=iOr_4JzZeyQ

Only molten steel would be unusual. He says "molten metal"
And you do have a lucid explaination for this NIST fumble below? ITAR, right?

What is your worst interpretation of the "fumble"?
For the sake of discussion, let's assume it's true. How does that affect the basic conclusion, that protracted fire and lack of water for firefighting caused the collapse?


ITAR isn't my specialty. I have a hypothesis that hasn't been discussed here because I have not mentioned it before, that parts of WTC7's data was withheld because it would reveal information about the type and scale of secret government activity based there. I could have been large NSA site. WTC7 was literally a few feet from one of the largest telephone exchanges in the country; 140 West St. This is just conjecture on my part.

What exactly is the supposed significance of the molten "Steel" in the weeks after the collapse supposed to mean? Seriously. That the temperatures in the pile were high? Nobody disputes this. That here were fires inside the pile from the 200 some odd acres of office supplies intermingled with the rubble? Nobody disputes this either. It doesn't prove anything at all other than that there were fires and that there was fuel for those fires. Therm*te burns off in minutes. Not hours, not days and most certainly not weeks. It does nothing at all to further your argument but it does make you look like you're grasping at straws at any cost.

Again, my salient point. What are you trying to show with your claims of molten metal or steel? Assume that you're correct and it's been verified to be molten steel (I'm not conceding the point but playing "What if"). What do you think it means?
 
well rivers of molten steel would indeed be very strange i think.
 
There were first hand witnesses to molten metal seen in the WTC clean up site. Included in this witness group is University of California, Berkeley Civil and Environmental engineering professor Abolhassan Astaneh-Asl, Ph.D., P.E., who was the first scientist given access to the steel at ground zero. Dr. Astaneh-Asl referred to the WTC steel he found as "kind of melted." Years later, when asked again about his experience he clarified, "I saw melting of girders in World Trade Center." As of this writing, there has not been a single reasonable or lucid explanation to address how this steel could have melted. Furnace blast conditions are difficult to achieve outside of a control volume, such as those within a cupola furnace.

Quite apart from Professor Astaneh-Asl's personal rebuttal to this claim, your statement that there is "not a single reasonable or lucid explanation to address how this steel could have melted" is completely untrue. The phenomenon observed by Astaneh-Asl has been described as eutectic melting of steel in a sulphur-rich atmosphere at temperatures accessible to a hydrocarbon-fuelled fire, and the large amounts of wallboard present in the rubble pile have been identified as a likely source of the sulphur. What is in fact lacking, as other posters have pointed out, is any other reasonable or lucid explanation of this phenomenon that suggests the presence of explosives or incendiaries in the building before or after collapse.

In fact, the erosion of steel observed by Astaneh-Asl is completely unlike simple melting due to high temperatures, because simple melting will invariably produce rounded edges due to the action of surface tension. The eutectically melted steel members are well known to have showed thinning and sharp edges, a result quite obviously more similar to corrosion, and hence indicative of some kind of chemical, rather than purely thermal, attack on the material.

All this is rather obvious to anyone who hasn't decided in advance to disbelieve it.

But what does it indicate in the weeks following the collapses (again, not conceding the point)? The energy of the collapses are over. Any supposed therm*te is long since burned off. Why are any molten metals (steel or otherwise) evidence of anything other than hot fires fueled by about 200 acres worth of office supplies in what equates to a relatively loosely compacted landfill?

What does it mean towards the truthers ideas as to why the towers collapsed?

You used to agree with them so I'm hoping for an insight as to why they fixate on this as a key point for their arguments.
 
Structural steel has a thermal conductivity of 46 W/m/K, which means that any heat applied is easily wicked away. But if that value were set to zero, or near zero, any heat applied would allow the temperature to rise dramatically at the point of application.

Tell me a welder didn't just say that. :confused:
 
Much credit for this information goes to Ron Brookman P.E., Kevin Ryan, Jonathan Cole P.E., mechanical engineer Tony Szamboti and Richard Gage AIA of Architects and Engineers for 911 Truth. www.ae911truth.org

Oh man. This list of names and linking to Gage's site is a biiiiig mistake. If any professional engineer googles those names or goes to that site, they'll be laughing. This is a sincere advice.

1. Steel, not metal, steel needs alot energy to be molten, and i have troubles beliving the conditions at GZ were enough to do that. Other metals, sure, but not steel. and i mean really molten like in "rivers of molten steel" not just some yellow glowing steel profiles.

that would have been strange in my eyes. what would that mean?
i dont know. as a truther you look for everything that looks strange to you or confirms your oppinion. I think you are right about themite not able to do it weeks after the collapse.

i also used the same video clips to "prove" molten steel has been spotet at GZ. Only because i belived it to be strange. wihtout beeing able to answer what that means in detail.

I think it was "welding inspector" not welder, qualifications could in theory be down to "Yep, that is a welding".

(I have heard of people getting fooled by carefully applied silicone and a paintjob)

Provide context to show that
a) This is a first-hand witness account
b) or they are at all agreeing with the things they menion in those 13 seconds, and not mocking them

1500F (=815°C) isn't even enough to melt steel, and is entirely within the range of the most ordinary fires (smouldering peat in forests routinely reaches 600°C). And all this a full SIX WEEKS after the collapse. What is your point?

And this guy is lying through his teeth, right?
http://www.youtube.com/watch?v=iOr_4JzZeyQ

Is he talking about steel at all?

And you do have a lucid explaination for this NIST fumble below? ITAR, right?

Moving goal posts. Please stick to the molten-steel-topic when we are attacking you on it and you try to defend it.

it sure took more time to fake the welding than actually welding it :)
 
Yes, hopefully he will respond and clarify his statement.

But meanwhile, you'll continue to besmirch his name by claiming that he supports your stand. Even tho you've been shown a clear, concise synopsis of his view on the subject.

So, your religious views permit you to lie "until some guy gets around to answering your e-mail"?

Just out of curiosity, what else was in that e-mail. The usual Wall-O-Text Truther Woo that you bring here? Just like this post? The type of nonsense that is guaranteed to get your message sent to the Trash (or Looney) Bin?

How about you cut & paste JUST the text from the Ron Weick letter, send only that to him & ask him if this is a correct encapsulation of his over-all sentiment on the issue.

Or pick up a phone & call him.

http://www.youtube.com/watch?v=YqNugYbZX7E

No, they meant something.

But it was not "molten steel running down the channels".

What do you get, INEVITABLY, as a result of "molten steel running down {presumably steel) channel rails"?

Well, you get several things.

1. Melted channel rails that can't carry any more molten steel.
2. If his description is intended to be representative of the first 3 months of operations, then the molten steel runs down the rails for three months produces a LAKE of once molten, later solidified steel. That no truck can possibly transport.

Where are the reports of the hundreds of guys that it would have taken, with flame torches, to cut up this lake of steel?

If the molten steel ran for just a week, then you've got a small pond of solidified steel. Or any other metal, for that matter. There are LOTS of pictures of the steel from Fresh Kills. Show me hundreds of pieces with one giant flat cooled top surface, a whole bunch of entrained debris in the opposite very irregular surface, and sides that have been torch cut to allow transport off site. There ought to be many hundreds of these pieces. And hundreds of reports of the laborious work to cut them up & move them.

Instead, we have lots of reports, and photographs, of twisted, mangled (and not so mangled) UN-melted steel beams.

For that matter, show me any PARTIALLY melted steel beams. The Barnett-Biederman-Sassoon beam is NOT melted. It still retains it original shape, while greatly thinned down. This is characteristic of corrosion, not melting.

When something melts, it turns into a liquid & loses it solid shape.

Show mw some steel beams that transition from I beams to puddles. NOT "bent, twisted but still recognizable as mangled I beam" samples.

You show me some several dozen examples of THOSE I beams and THEN I'll start to give credence to "molten steel".

This worker didn't really guess that it was 1500 degrees or that it was red hot almost six weeks later. He really meant something else, right?

http://www.youtube.com/watch?v=IrrJCa1haaY&NR=1

No, in fact, he did not mean that "it was 1500 degrees".
He meant what he said. Which was "it's probably 1500 degrees".

Now he is probably right. But you don't have the right to drop qualifiers from people's comments, thereby changing the meaning of their words to suit your purposes.

That is dishonest. That is lying.

And you'll note that 1500° is not sufficient to melt steel.
And that 1500° is exactly the kind of temp that you'd expect from burning a huge amount of buried office rubble.

What amount of ordinary research have you done to try to get a handle on the thermodynamics of the burning rubble. What temps it should have achieved, how fast it should have cooled, etc. Have you checked the literature? Have you done any BOTE estimates of your own to see if that length of time to cool is shocking. Or unreasonable. Of perfectly within the realm of "to be expected"?

What keeps these underground fires burning:
http://boingboing.net/2009/06/16/giant-burning-holes.html

Did someone plant thermite down there?

"Bright, bright reddish orange" down there.
Hydrocarbon fire: coal.
In the towers? Hydrocarbon fires: paper, wood, plastics.


And this guy is lying through his teeth, right?

You keep casting the interpretation of eyewitness memory into one of two states: completely true or "lying thru his teeth".

Experienced investigators (of all types) & researchers in memory would say that your understanding of memory is as flawed as, say, your understanding of the speed & forces involved in buckling failure.

I don't believe that he's lying at all.

He's wrong.

But he's not lying.

There was a very well documented stream of molten [something] that came tumbling, perhaps pouring out of the towers.

He's wrong in saying that it came from "at least 3 different places". It came from one place.
He's wrong in saying that it came from an area that was undamaged. It came exactly from the floors where the airplane debris came to rest.
He's wrong in describing explosions & detonations.

How do we know, with absolute certainty, that he is wrong? Because we have hundreds of video tapes, taken from all sides of the towers that prove his statements above to be incorrect.

It seems to me that YOU are the one who is accusing him of lying about those things? Because you've eliminated the possibility of simply

Or is he perhaps, like most honest witnesses, right in overall tenor, but wrong in a couple details.

BTW, he does not say "molten steel". He says "molten metal".

He's probably right about that detail. Not certainly. But probably.

it sure took more time to fake the welding than actually welding it :)

No, actually not, particularly if it is somewhere away from the welding shop and you have to set up the welding gear.

I saw one example where port state inspectors held back a ship where cracks in the deck were "welded" like that.
 
The only difference between me and others at JREF is my mind is not made up. I'm still open to the possibility that WTC 7 was designed wrong, although NIST isn't helping matters.

"Designed Wrong"? Are you really an engineer?

I'm quite open to it having a design detail(s) that contributed to its failure under exceptional circumstances as of course so did the WTC Towers. I don't recall anyone saying that a different design for both the towers and WTC7 would not have slowed or perhaps even prevented their complete failures.

But thats just hindsight......good solid cockpit doors and a warning to crews about possible hijacks and use of aircraft as weapons would likely have saved those building ever being tested beyond their design limits.


Do you concede the Molten metal issue yet?

.


i have heard that case beeing made about the towers, concrete core would have preventet it propably, well that was the claim.
 
So let's consider "molten steel", for instance.

I went looking for the truth. I attempted to contact witnesses to find out what they saw and how they knew this was steel.

Meanwhile, it appears to me you've done nothing more than cut and paste witness lists from truther sites. You defend these despite being entirely unable to explain how the witnesses distinguished steel from other metals. And you handwave away what witnesses actually said on the grounds that those reports come from "biased" sites

So it also seems to me that, on this issue at least, your mind is very much made up. You're not looking for the truth, you believe you've found it already, and just like any other truther, you will try any old trick to ignore contrary arguments and information.

Amen.

Derek: You ready to remove Barnett from your cut & paste library yet?
