Commentary on Killtown's piece
Category: 911
While it is impossible to discount the possibility that some form of "assistance" such as thermite was used to initiate the collapse of the towers and WTC7, the explosions on the basements and lobbies of the buildings have a benign explanation.
Remember that two passenger jets full of aviation kerosene crashed into the buildings. Contrary to the official story of pooling on the impact floors, all the kerosene that did not immediately flash into orange flame poured down elevator and ventilation shafts to the lowest levels in the building, particlizing on the long drop down. Upon finding any source of ignition, the kerosene mist would explode. The buildings all shared a common basement and parking areas, so that burning kerosene in the basement of one building would drive smoke across and up into the other buildings. As the towers and WTC7 collapsed, air driven into their elevator and ventilation shafts into those shared underground passages would blow huge billows of smoke out of the other buildings.
The reason not to get tied up with reports of explosions in the basements and lobbies is because anything planted in the buildings to trigger a collapse would have been planted at the initial points of failure. And, considering the attention being focused on the events of 9-11, the planners would not use explosives that would produce suspicious noise and flashes. The collapse would have to be triggered with a minimum of visible and audible artifacts, so rather than explosives, a "cutter" such as thermite would have been used to weaken load bearing members.
"Betonamit" "DEXPAN" and "Bristar" and " Fract.AG expansive mortar " are all "explosives that would produce suspicious noise and flashes." As a matter of fact, they do not even explode. These substances as marketed as non-explosive alternatives to fracturing rock of re-inforced concrete. Just drill a hole, place the powder in and then add water -- via a sprinkle system or carefully placed hoses. Then run for dear life.
Depending on the type of SCDA(Soundless chemical demolition agents),
significant expansive pressure may be generated as quickly as within 15 min., or as long as within 24 hr.

Soundless chemical-demolition agents (SCDAs) — These come in powder form and are mixed with water to form a slurry, which is inserted in boreholes in rock or concrete. The main component of SCDAs is calcium oxide, which forms calcium hydroxide when water is added. The resulting volatile reaction creates heat, and as the material crystallizes within the rock, it causes a threefold increase in volume. Tensile fracturing may occur within 10-15 minutes or up to 24 hours. Although inhibitors can be added to retard the chemical reaction and increase control over the process, the technique is still primitive, and its actual field use has been quite limited. SCDAs have generally been used only where blasting is prohibited, and will eliminate flyrock, noise, fumes, and vibrations associated with blasting. SCDAs have been used underwater in Seattle to remove bridge piers from docks and to avoid blasting close to shore. The high cost of SCDAs and some bad experiences in controlling the pre-splitting have caused the Corps of Engineers to limit its use of the expansive agents.

BRISTAR is a chemical-demolition agent designed for various temperature ranges, and has been used for several Reclamation projects. It generally requires holes from 1½-2 inches in diameter spaced less than 2 feet apart.
The south tower, WTC 2, which had been hit second, was the first to suffer a complete structural collapse at 10:05am, 62 minutes after being hit itself, 80 minutes after the first impact.
The north tower, WTC 1, then also collapsed at 10:29am, 104 minutes after being hit.

Collapse times
South Tower -- 80 minutes, approx one and a half hours
North tower -- 104 minutes, approx two hours
Greater Baton Rouge Business Report - November 1, 1990
Diana Armstrong knew a good opportunity when she saw it. She ran across the product last year at a trade show and now she is distributing Betonamit in some 20 states, Canada, Mexico and the Virgin Islands.
Representatives of Kubatec, the European company that makes the Betonamit powder, were looking for an American investor. At the time, the product was widely used in Europe, but it had not been introduced to the United States.
Armstrong said she researched the company, visited its lab in Liechtenstein and tested the product before buying into the idea.
<snip>
"Louisiana doesn't have any rock," she said. "I had to start with places where there was already an interest in my product, so I started in the Northeast."
For example, one of Betonamit's largest clients is the New York Transit Authority.
"The workers are continually making repairs on the subway system, but they can't blast. And because they do most of their work from 11 p.m. to 6 a.m., they have to hold down on the noise," Armstrong said.
She has also provided Betonamit to NASA at Cape Canaveral in August where workers used Betonamit to tear down a submerged concrete piling near the base. And in Washington, engineers used the product for a sensitive job 500 feet underneath a hydroelectric plant.
Although, Armstrong handles some of these special jobs personally, much of her business is through distributors.
Her largest distributor is an Ohio hardware salesman who serves as master distributor in the New England area. She's also established master distributors in Canada and Mexico.
<snip>
Betonamit's competition is two similar Japanese products sold in the United States--Bristar and S-Mite. But Armstrong claims the products lack some of the qualities available with Betonamit.
Betonamit can be used at any temperature, with warmer temperatures increasing the speed of the expansion process. The reaction exerts up to 12,000 pounds per square inch of pressure. And depending upon the size of the structure and the temperature, the demolition process can take as little as one and a-half hours or as much as 36 hours, Armstrong said.
Because the product is easy to use and ecologically safe, Betonamit requires no license or permit for use or transportation.
The product comes in two types: Betonamit Type R is the standard liquid form used to fill vertically drilled holes; Type S is a putty-like, kneadable mass that can be put into holes drilled overhead and horizontally, as well as holes in porous or cracked material. It can also be easily used in underwater applications.
The Japanese products, however, require three to four additives depending upon the temperature, and they're limited to the liquid form, Armstrong said.

How utterly convenient is the fact that these non-explosives do not require permits of any type.
U.S. ANCHOR'S COMPOUNDS FUELING COMPANY GROWTH
Magazine: South Florida Business Journal, February 24, 1995
Though U.S. Anchor has an answer for many South Florida building ills,
president Hart McIntyre insists his company doesn't sell products. "We
sell solutions," he said.
<snip>
The company also has searched the globe for products generally not
available in the states. One is Upat, a line of mechanical anchors.
Another is Kubatec, a European product sold under the name Betonamit.
When mixed with water, this non-explosive demolition material can
produce 12,000 to 14,000 pounds per square inch of pressure, effectively
shattering any rock or stone substrate without explosion or spark. It
may be more expensive than dynamite, McIntyre admitted. But in areas
where blasting is unrealistic or will violate restrictions on noise or
flammability, like hospitals or office buildings, Betonamit is a viable
alternative.
"When you're willing to put a pencil to the job-costing process, this
can be the way to go," he said.

When the twin towers collapsed, the Port Authority Trans-Hudson Corporations WTC commuter rail station underneath the site was destroyed, along with one unoccupied train. Also, transit tunnels and stations at the site were severely damaged, causing interruption of MTA New York City Transit subway service on two lines.
A special commemorative issue of At Your Service, the NYC Transit employee newsletter, described the damage: nearly 1,400 feet of subway tunnels beneath the towers had caved in or had filled with rubble; utilities had collapsed into the tunnel; columns from the World Trade Center had pierced the tunnel roof; and two-thirds of the Cortlandt Street Station on the WTC site had also given way.
According to NYC Transit President Lawrence G. Reuter, who moderated the session, the restoration of subway service through Ground Zero and the reopening of one of the Rector Street Station in less than nine months was one of the most successful subway-infrastructure reconstruction projects in the systems history.

I thought that the third rail on those trains is electrified.
How come there were no spontaneous fires in the vicinity, and most especially fires involving gas lines?
How come the tunnels were not flooded with water? Who shut off the mains?
Anyhow, it is very very gratifying to see thermite
(and hopefully later cementitious compunds)
entering the mainstrewam 911 debate.
