Thermitic Pyrotechnics in the WTC Made Simple

Three Points of Active Thermitic Material Discovered in Dust from the 9/11 World Trade Center Catastrophe that Anyone Can Understand

by Jim Hoffman

Version 0.7, April 18, 2009

Introduction

The scientific paper Active Thermitic Material Discovered in Dust from the 9/11 World Trade Center Catastrophe provides, quite simply, proof that explosives were used in the destruction of the Twin Towers. Specifically, the paper positively identifies an advanced engineered pyrotechnic material in each of several samples of dust from the destroyed skyscrapers, in the form of tiny chips having red and gray sides and sharing a very specific three-dimensional structure, chemical composition, and ignition behavior.

The basis and validity of this identification can grasped quickly by anyone with a working knowledge of physics and chemistry. They need only read the paper's one-page conlusion, and perhaps its section describing the provenance of the dust samples.

But what of the reader whose strong suit isn't the hard sciences? Does one have to be an expert to understand the findings and evaluate the many claims thrown up by "debunkers" to dismiss those findings?

Fortunately, the answer is no. The central observations of the paper can be understood by any intelligent person with some effort. In this thumbnail summary of the paper's findings, I focus on three easy-to-remember features of the red-gray chips established by the paper -- features that undeniably show that the chips are a high-tech engineered pyrotechnic material. Because my description includes some technical language, I have provided a glossary for the benefit of the non-technical reader.

UPDATE

This thread is only about the three scientific points made by Jim Hoffman in his article, or related points about the science of the thermite paper.

It is NOT about:

* theories about chain-of-custody

* theories about the Bentham Scientific journal

* theories about Dr. Steven Jones or the other scientists

Moderators; please delete any posts that are not germane to this thread. Thank you.

Shouldn't this be merged into one of the numerous threads about this subject? Isn't this actually more of an issue that should have been posted in those pre-existing threads?

They simply didn't exist.

 

[Galileo]

They simply didn't exist.

The scientists found them. You have not the WTC dust, the scientists did.

No, this thread is focused on the elementry science of the thermite finds.

It will not be bogged down by conspiracy theories. It will focus only on what the scientists found, and the science behind it.

But this one centers on Hoffman's blather.

Dim bulb seems not to think it significant that the reagents are not uniformly distributed through the chips.

Dude, that works for paint. The elements found are supposed to be in paint.

Inhomogenous mixtures of incendiaries and explosives are generally useless.

It's PAINT, you moron.
Stick to teaching math, Hoffman.

Too late.

please read the update.

Okay, well it doesn't really provide anything new. There is still the issue of not being able to show that these chips are anything other than paint. Honestly this has been covered in the other threads.

It is paint.

No the scientists did not find the samples they were found by various individuals.

Why did they have to go all the way to the Brooklyn bridge for a sample? I would think ground zero where the debris was would be the best place to find a sample of the debris.

I quit buying bridges from strangers some time ago.

Maybe the light was better there?

repeating this lie doesn't make it true

It has never been true since 9/11/2001


get a new act gallileo this one is getting quite old

 

[leftysergeant]

please read the update.

He still shows inconsistant make-up from one chip or part of a chip to the next.

Okay for paint, but it kills therm*te.

Are you using "thermitic pyrotechnics" as a synonym for "paint chips"?

 

[Galileo]

This thread is about science.

It is NOT about faith-based appeals to your "authority".

No, I am not.

you argue from faith-based authority, not from science.

I would like to give a friendly warning to the JREFers:

There are a lot of lurkers out there who come here to see if the thermite paper can be debunked based on science.

If they come here and read these faith-based authority appeals, they will not be convinced.

 

[Dog Town]

...
It will not be bogged down by conspiracy theories.

So why did you post this in a conspiracy sub-forum, exactly? 911 at that...

It will focus only on what the scientists found, and the science behind it

If it's all sciency, and stuff, post in the SCIENCE forum!

 

[Dog Town]

The funny thing is, you are the one running on blind faith, not us.
You are right though, lurkers see you get demolished time, and time again!
It doesn't help your side a bit!

This is the Jim Hoffman that wrote this?

The replacement of ceiling tiles throughout the building may have been done on any of a number of schedules. On the one hand the tiles could have been supplied as part of an maintenance contract and installed using the existing building maintenance staff doing what they thought of as normal building maintenance work. Since the new landlord had just taken over in late July of 2001, it wouldn't seem at all unusual to see some refurbishing, especially as unobtrusive as swapping out old ceiling tiles.

Alternatively, the tiles could have been installed during overnight hours by a team of maintenance workers unnoticed by tenants. The logistics of such an operation can be imagined, and some estimates of human resources made.

We know that the Towers had only two types of ceiling tiles: 20-inch squares for the tenant spaces and 12-inch squares for the core spaces. An estimate of the number of tiles per tower is 1,200,000 large tiles and 800,000 small tiles.

The new ceiling tiles with embedded thin-film explosives and wireless detonators are installed throughout every other floor of the Tower. In all, each Tower gets 500,000 of the large tiles and 400,000 of the small tiles.

With workers swapping in new tiles at an average rate of two tiles per minute per worker, it takes a team of fourty workers 187 hours to retrofit an entire Tower. The work is performed in three weeks and weekends of night shifts, emptying one truckload per night, with the truck parking inconspicuously in the WTC subterranean parking garage.

That Jim Hoffman?
