Free fall acceleration means No resistance. The NIST model always provides resistance.
Does free fall acceleration mean controlled demolition?

Dave,Chris, good job on the debate with Gage. I know how slippery he can be.
Anyway, check out this YouTube video:
It clearly shows that parts of a collapsing structure, pulled on by othert parts of the same structure, can actually fall faster than objects in true freefall.
And note the complete absence of explosives!
Good luck, Dave Thomas

An analogy does not depict what actually happened. We can look at Figure 12-63 and see the frame twisting and buckling in an irregular manner. Then looking at the screen captures we can see that this buckling is occurring during the free fall acceleration. Buckling columns provide resistance. Because of the irregular manner of the buckling exterior columns, they do not all buckle to the point of failure at the same time. The vierendeel action of the perimeter moment frame transfers the resistance of the columns in a lesser stage of bending. So, as Shyam Sunder said [when NIST was denying the existence of free fall] "there was structural resistance that was provided in this particular case. And you had a sequence of structural failures that had to take place. Everything was not instantaneous."Chris, this does make sense to me. Another analogy Ryan gave me once was like a stick you lean on, and it holds up until it breaks.
No, we are talking about free fall. Air resistance is negligible - too small to be considered. The NIST measurement was within 1/10th of 1% of free fall acceleration which is negligible, i.e. there was no measurable resistance.And of course we all are talking about near free-fall due to air resistance in any kind of collapse.
Buckling columns provide resistance.
Hi Chris, Now on to the second thought experiment. "That's just one column," you're thinking, "and we added weight until it collapsed. WTC 7 didn't add weight." That's correct.

Hi gang,
In my March 6 debate with Richard Gage, a scientist friend of mine said that the side by side spectographic analyses Richard showed on a slide re thermitic dust showed two different chemical signatures. Anyone know about this. Anyone have a link to the pay phone explosion sound (someone said it was dubbed in; I would need the original to compare it to back to back if this is true).
Anyone willing to slog through the 3 1/2 hour debate and pick out inaccurate things Richard said that I missed... I will have one last chance to rebut it all in about four weeks. Link to debate is on Richard's AE911 Truth website... I'm still not allowed to create links on JREF, sorry.
In the final report NIST said the buckled columns provided "negligible" resistance. This gives the impression that there was some resistance when there was none. If the resistance is too small to be measured, it is for all intents and purposes, zero.
The use of the word "negligible" is an obfuscation of the fact that the buckling columns did provide resistance as Shyam Sunder stated: "there was structural resistance that was provided in this particular case. And you had a sequence of structural failures that had to take place. Everything was not instantaneous."
"There was structural resistance" and "negligible resistance" are not the same.
ETA: Somepeople refuse to accept the obvious:
"a free fall time would be an object that has no structural components below it.
I will read the article tonight. Just looking at the spectrum of the nano-thermite chips I don't see any of the things that the RJ Lee Group was looking for. I'll get back to you when I have finished studying Kevin's paper but it would be better if you address your questions to him.A couple days ago Chris wrote:
"The nano-thermite chips were iron oxide, aluminum silicate and organic materials. There was no significant amount of the toxic components that they were looking for."
Well, chemist Kevin Ryan recently published an article stating that the first responders are getting sick these days because they breathed in all this horrible thermitic dust. He listed all kinds of thermitic toxic chemicals he thought were part of this deadly soup of hazardous materials.
Chris, have you read this article? Which is it? Benign thermitic materials or hazmat?
Thank you. I also appreciate your arguing the data and not attacking or insulting your opponent.Us two Chrisses have one thing in common... we voluntarily surround ourselves with our adversaries: me with truthers and him with, well, us. Chris I admire your spunk, as many truthers admire mine.
Two different moments
Same collapse
No structural components
Air is not a factor in this case
Also my spectograph question is this: do they show the same thing?

I have read Kevin Ryan's paper and it's clear he says that thermitics are terribly toxic. Nothing more to ask him. My question would be to you, since you assert that breathing in unexploded thermites would not be the kind of health hazard the RJ Lee study would be concerned about.
Kevin Ryan did not say that the red/gray chips are toxic. He said the extreme heat they created released benzene and other toxins from plastic and polystyrene in the dust.If you agree with Kevin Ryan (and I for one would NOT want to inhale nanothermites, thermates and their byproducts) then why didn't RJ Lee find these deadly toxins?
You can look at the spectrographs of the unignited chips and see for yourself that there are none of the things that the RJ Lee Group was looking for.Also my spectograph question is this: do they show the same thing?
