FAQ # 7: Squibs

Q:

What caused the “squibs”? Could they have been just puffs of dust being pushed out of the Towers by falling floors? Are they visual evidence of explosive charges?

A:

The isolated ejections 20-60 stories below the demolition front appear to be composed of pulverized building materials, including concrete. There was no known mechanism by which pulverized building materials being created up at the zone of destruction could have been transported so far down through the building and to the exterior. Air conditioning vents would not have tolerated such pressures, and there was no other “channel” in the building to deliver “compressed air”.

There is no reason, on the “dust puff” theory, for such blasts to be as isolated as they were.  Massive air pressure which would delivered by the (missing) “pile driver” down through the elevator hoist ways and out through a given floor would have broken most or all windows on that floor – not created the highly focalized pin-point ejections that are seen on the videos. The breakage of one or two windows on a given floor would not have relieved enough pressure across an entire floor area to prevent the breakage of many other windows nearby.

Images like this one reveal that the squibs were not merely puffs of air, as they have the same hue and consistency as pulverized solid building materials

Multiple analyses have shown that the ejection speed of the squibs was too high, at 100+ mph, to have been the result of air pressure. These are explosive speeds. They have also been clocked at 160 to 200 feet per second.

Another problem with the “dust puff” theory is that the pulverized building materials would not have been transported so quickly.  Air would have been pushed ahead of such materials, resulting in transparent puffs of air flowing through the freshly broken windows.
Physicist David Chandler has also shown that some of these ejections came from the corners of the buildings. Since there are no windows on the corners, these ejections could not have been the result of air pressure.

The Explosive Nature of Nanothermite

The explosive nature of nanothermite

By Kevin Ryan   source: Dig Within    June 24, 2011

In the last few years, a series of peer-reviewed scientific articles has been published that establish the presence of thermitic materials at the World Trade Center (WTC). [A-D]

Although we know that nanothermite has been found in the WTC dust, we do not know what purpose it served in the deceptive demolition of the WTC buildings. It could be that the nanothermite was used simply to drive fires in the impact zones and elevator areas – fires which would otherwise have gone out too early or not been present at all – and thereby create the deception that jet fuel-induced fires could wreak the havoc seen. Nanothermite might also have been used to produce the explosions necessary to destroy the structural integrity of the buildings.

Nanothermite, also called superthermite, is the common name for a subset of metastable intermolecular composites (MICs) characterized by a highly exothermic reaction after ignition. Nanothermites contain an oxidizer and a reducing agent that are intimately mixed on the nanometer scale. Such nano-energetics are produced for various applications including propellants, explosives, and pyrotechnics.

There are various ways to make nanothermites. They can be made as solid mixtures of aluminum and metal oxides which are typically produced using techniques like dynamic vapor phase condensation and arrested reactive milling. These mixtures are much like typical thermite mixtures, but with the components introduced on a much smaller scale. Alternatively, nanothermites can be made in a liquid solution that later gels, capturing the reactive components in an intimately mixed composite which is dried before it can be ignited. These are called sol-gel nanothermites, also known more generally as energetic nanocomposites.
