Chemical Traces of High Explosives in WTC Debris

Many scientists and engineers have looked at the way the WTC towers fell and remarked that it had the appearance of controlled demolition. The buildings collapsed symmetrically, and fell straight down. The speed of the fall indicated that the buildings were collapsing unimpeded.

There is a science to placing the charges in such a way that the building falls inward. It requires a great deal of expertise to keep a tall building from toppling over sideways.

Many scientists and engineers have looked at the way the WTC towers fell and remarked that it had the appearance of controlled demolition. The buildings collapsed symmetrically, and fell straight down. The speed of the fall indicated that the buildings were collapsing unimpeded. They must have had the “legs” simultaneously pulled out from under them, because a layered collapse from the top down would have taken several minutes, whereas the observed collapse took place in less than 20 seconds.

Another anomaly in the WTC collapse was the violent explosions. Firemen reported earthshaking blasts from the basement before collapse, and the impact areas in the upper floorss of the buildings exploded just at the onset of collapse. Jet fuel burns but cannot explode.

In an article published this week in the journal Environmentalist, chemical engineer Kevin Ryan collects evidence from EPA documents that suggest there was both Thermate and high-explosives in the debris from the WTC collapse. Ryan was formerly employed by Environmental Health Labs, a division of Underwriters Labs, before he was fired for raising these and other questions.

Has anyone ever discussed the possibility that some super skyskrapers were engineered to be destroyed one day, to collapse in its own footprint?

Is it possible that the wtc was pre rigged by explosives as a saftey measure to ensure the buildings dont fall over multiple city blocks like in the case of of the 1993 bombing?

Ivan,

This has been discussed before.

One simple question:

Can you please list all Controlled Demolition Experts that have stated that WTC's 1 & 2 looked like a controlled demolition.

Thank you,

-TY-

Why do we need CD experts to say this?

This looks pretty much like it.

So much for "buildings are NEVER demolished from the top down" eh?

Also, this is what I would expect from a building progressively collapsing on one side (WTC 7)

video.aol.com...

I'm more interesting in seeing documented proof that fire has caused steel-framed buildings to collapse after 2'ish hours of burning.

I once watched my kerosene heater burn for a bit and guess what...it never melted!

Because ALL CD experts have stated that 1&2 DO NOT look like a controlled demolition. (including the one that said WTC 7 does look like one)

If it looks like control demolition.
Smells like control demolition.
Sound like control demolition.
Then IT IS CONTROL DEMOLITION!

Funny, there isn't a single expert that agrees with you.

Should I disregard their statements and go with yours? Or Dora's?

In regard to your Original Post, Ivan, I thank you for sharing the report with us. There were some VOCs that I hadn't seen previously in test results for the WTC and surrounding area, 1,3-diphenylpropane, in particular. I would have surmised that the majority of the PVC piping, ureas, and other plastics would've been completely burned and vaporized -- at least in the core areas. Good info, thanks.

p.s. I don't agree that free chlorides or chloramines were likely to have been in the 10% range or even anywhere near that, at least initally. That level would have been likely to combine with other aerosolized compounds, and could have been fatal, or at lease strongly hazardous to those downwind of the towers. Perhaps, though, there are reports to that effect I missed.

Cheers

P.S. -- your thread title thought...... Chemical traces of high explosives? I don't see that substantiated in your link. I'm making an effort to stay on-topic here, and not get once again distracted into peripheral issues. Would you mind highlighting in your EPA link where it identifies VOCs that are consistent with "high explosives?" I'm not talking about the aluminum. Aluminum can increase brisance in an explosion, but surely there were several tons of aluminum in the building.

Thanks

I'm sorry that I can't believe you when you state what all CD experts say and have said. Have you spoken to them all? Read their statements in their entirety? See what I'm getting at?

It's the same argument made that all structural engineers and ASCE members agree with NIST and disagree with Gage. Well, I'm proof that that statement is a delusion of grandeur, so I'm going to assume that the statement of all CD experts is also.

On topic: I have come to the conclusion that there is not going to be any headway made in claiming that explosive residue was tested positive or thermite etc. etc. Why? Because those same elements make up just about everything else throughout the building. Gypsum has sulfur, computer screens have bromium (I think), exit signs and watches have tritium etc. etc., so IMO it's a dead horse. Plausible deniability at it's finest.

Edit: Before someone looks up my name in ASCE, I am not an active member anymore. But, I would be willing to scan my certificate from ASCE and send it to a mod to verify that I was indeed a member.

That is a LIE!

tsk tsk


Please prove that I am lying

TY,I don’t need too, you know all the expert as I do, I am not going to waste my time this is a game infact its call the pissing game.

Most people already know that explosives were used to bring the WTC down. Nothing more need to be said thank you.

The VERY first thing i thought when i saw the towers collapse inside their own footprint was 'oh they're bringing the buildings down'...

Weren't those buildings DESIGNED to cope with aircraft collision?

I'm sticking with the rule of common sense, and common sense tells me that those buildings were brought down in a controlled order.

yes you do. you accused me of lying. Back it up

reply to post by cashlink


Disgustingly valid, but unsound argument. Don't simplify things on this serious of a topic.

reply to post by mr-lizard


Collision with a smaller aircraft. Look this up. It has been covered.

People need to stop with the common sense "arguments". There is no rigor or testing there, just talking and claiming. I know that the posters on this thread are capable of more quality than this.

Are you going to call all these people liers too.
This is a lot of reading, and watching videos, so I shouldnt here from you for a week right. because you can not read all of the truth in 10 mins.

Yes it has been covered. The buildings were constructed to sustain multiple impacts from 707's, the largest aircraft at the time of construction.

Please provide a link that states small aircraft.

Sheesh, this is the first time I've seen the small aircraft argument. The debunkers are running out of ammo, soon it'll be that the buildings were built to withstand model remote control airplanes.
