In opening I would like to thank chissler and ATS for sponsoring this debate. I would also like to extend my thanks to whatukno for agreeing to be my
debate partner in what I hope turns out to be an informative debate. I have no doubts it will be a friendly and open minded discussion on the
possibilities of what may have occurred on 9-11-01.
The events of September 11, 2001 were a tragedy for all of us and a real wake up call to the way the world works. You can apply that statement
equally if you believe the governments version of events of if you subscribe to any of the numerous alternative theories behind this event.
One of the main theories of the event that lead to the destruction of World Trade Centers 1, 2 and 7 are that they were in some way rigged with
explosives before 9-11. During the course of this debate I hope to provide some factual information about explosives, their properties, and what it
really takes to pull of an operation of this magnitude. In doing so, I hope to show how unlikely it is that High Explosives were in fact used in this
disaster.
During our debate, I will not go out of my way to prove or disprove our governments version of events, my opinions of the causes of the events overall
are not relevant to this discussion. I will also not attempt to prove or disprove how the buildings were actually destroyed as that is outside my
area of expertise and would be nothing but speculation on my part. My stance on the issues is STRICTLY LIMITED to the use of explosives, or rather,
the lack thereof
There are also 2 very key components of my argument that must be clearly stated at the outset.
1st is that commercial airliners did in fact strike the world trade centers.
2nd is that the resulting impact did in fact start large fires.
So I will not be addressing any issues relating to holograms, space lasers, etc.
So, to begin:
Demolitions 101
The first things it is important to understand about demolitions are some of the basic characteristics of them.
Charge type det velocity re factor
Tnt 23000fps 1
C4 26000fps 1.34
Sheet explosive 24000fps 1.14
Dynamite 20000fps 0.92
Anfo* 8900fps 0.42
Det cord 24000-32000fps
(*anfo=ammonium nitrate fuel oil)
(RE factor= relative effectiveness when compared to TnT)
So the first thing you’ll notice is that with the exception of anfo, almost all of these detonate very quickly and as you can imagine a supersonic
blast wave may make some noise, though that sound wave admittedly can be mitigated by using less explosive.
So that’s a great place to go next, just how much explosive are we talking about here?
Well if we were to use an arbitrary dimension for the core columns that is much smaller than the actual measurements (this is arbitrary I don’t have
the blueprints so cannot provide an actual measurement) of 12” square we get 4 linear feet. That will give us 1.2 meters. Now, if we were to
calculate using the smallest possible charge, that being a linear shape charge which typically has 1kg/m of RDX based explosive (C4) we get
1.2kg/column of explosive. This by itself seems miniscule and would make very little noise outside the building itself. However, when you multiply
that times 47 (the normally accepted number of columns in just the core alone) you get 56.4kg/floor of explosives. That’s 124lbs. for anyone to
think that even if you only used it to initiate the blast you wouldn’t hear 124lbs of explosives going off all over manhattan is just denial in my
opinion. Because for a symmetric, or near symmetric collapse you would in fact have to detonate them all pretty much simultaneously.
Also the fact that when a demo shot goes off, it does in fact leave behind small bits of undetonated material, shrapnel from the charge housing, bits
of shrapnel from blasting caps etc. There is always some type of evidence left behind.
The last factor I would like to present in opening is the effect on the impact of the planes on the pre-placed charges.
Explosives will NOT detonate just by being heated or lit on fire. They will burn when exposed to flame, and when exposed to heat will dry out and
harden, or they will melt. Any of these will lead to them becoming nearly useless as explosives. Also one must consider that the flames, or even the
damage inflicted by the planes themselves would in fact most likely lead to damage to the firing circuits.
So, to close my opening statement, based on the evidence we are able to collect:
The audio/visual evidence does not support explosives being used.
The physical evidence does not support explosives being used.
The basic properties of the explosives themselves do not lend to the likely hood that they were in fact used.
So ends my opening statement.

well deserved win!
