Testing for explosives

I keep seeing the twoofers complain about the lack of forensic tests for explosivies at the WTC sites. I am trying to figure out what test could possibly have been performed, beyond examining the steel for explosive marks and sampling the residues on steel so damaged and sampling the ambient air.

Anyone here have some useful experience in conducting such testing and an idea of what they could have tested?
 
Do you need to test for explosives to figure out what happened to this building?

Good point.

But, to answer the question, they would use some pads to swipe certain areas, look at the steel, maybe some ground samples, but, like Unloved said, is it really nessary??

Various ways you can do it. Generaly takeing samples from around the site where you think there was an explosion and running one of any number of tests depending on what you think the explosive used was.
 
I have talked to commander of Passaic County Bomb Squad - lectures our FD on bomb
procedures. He and his team spent several weeks at site doing search/rescue. They
did not discern any signs of explosive demolition- no blasting caps, pieces of det cord
or shock tubes to wire charges togather, no pieces of fencing/metal sheeting used to
secure charges around columns.

Explain to the idiots that members of the bomb squad spent weeks crawling over scene
doing search/recovery - none of them spotted anything as belonging to an explosive
demolition.

Yeah, but they were REALLY concentrating on search/recovery? It leaves liitle time for searching for explosive residue, DOES IT?

Capitalization caused by my channeling a Truther. You may ignore it.

Yaah, everyone knows when you need search and rescue you call the bomb squad. Maybe that was standard procedure back then.

The NYC bomb squad including their dogs was deployed to WTC on 9/11 and for days afterwords.
 
wait, are we now accusing the NYPD Bomb Squad of suppressing the truth? that makes them co-conspirators!!

they are in on it!!
 
It did seem painfully obvious to me that nobody in their right mind would have tested every piece of steel in that mess. Wouldn't the EPA sampling of the air have picked up some trace of just about anything useful for demolitions?

I have already brought up the fact in any of my conflicts with twoofers that thousands of cops and fire fire fighters and investigators had been clambering all over the wreckage and never saw anything worth checking out further, but, to those little pea-brains, what difference does that make?

Let's go at this from another angle. If CD had occurred, what airborn traces would have been present in the smoke and dust?

I find that when this is brought up that Truthers start talking about metal meteors and pools of molten steel. As that even consistent with what happens after a CD? I ask that and they never give an answer.

Not really sure why you're even asking this question lefty. Two commercial aircraft fly into two high-rise buildings which subsequently collapse, so we entertain the possibility that CD was the cause! Isn't that analogous to, say, investigating whether somebody over-filled a bath in New Orleans on 25 August 2005? :rolleyes:
 
Southwind,

Great comaprison!

Anyway, here is my biggest problem with 9/11 CT. Think of the amount of people who would have known about 9/11 to cover it up. Think of the hundreds of thousands of people. How much money would it take you to cover up the biggest mass murder in US history? $100 $200....HECK NO!! I am talking MILLIONS!! (And I swear on everything that is holy, when I go to ground zero this year, if I hear ONE CT say FDNY was in on it, I am going to go batpoo crazy)

So, figure that about 500,000 people have to be in on their little conspiracy. Heck ASCE has 150,000 people just by its self. If you paid each on, say 50 mil (I would say thats about the going rate for a coverup) that woule equal something like 250,000,000,000,000

Yep, thats 250 TRILLION dollars!! Sweet baby jesus........

Be serious. Are you saying that they were brought in to help get rid of the evidence of explosives?

Is this something you've always thought or did it just pop into your head as soon as you saw this thread?

You are making a dangerous assumption in that last sentence.:):jaw-dropp

Generally speaking, nothing of value:

TNT:
2 C7H5N3O6 → 3 N2 + 5 H2O + 7 CO + 7 C

Nitrogen, water, carbon oxide (which will go into carbon oxide in no time) and elemental carbon, aka soot. It will likely burn into carbon dioxide in the moments after explosion.
End result are three of the four main components of our atmoshphere

Nitroglycerin, a component in many military explosives, and other nitrogen based explosives isn't much better in this regard.

You might get lucky and pick some undetonated explosive in the vapors, though the high temperatures make that highly unlikely. Nitroglycerin decomposes at 60°C (~140F), before even boiling, TNT at nearly 300°C, but again, decomposes before boiling. Plus you'll need a mass spectrometer to detect them, and there is a lower limit of how much you can still detect.

Scraping surfaces might be more productive, but then again, if there was an explosion that tore apart the steel in question, the visible marks will be very hard to miss, even to a non-expert.
