Study Backs Up Feds' Theory of Why World Trade Center Collapsed on Sept. 11

The Sept. 11th attacks also took place EXACTLY 3 months later to the very day when my pet cat Sam ran out into the road in front of my house and got hit by a truck driven by a government employee who had just gotten back from a visit to New York and the World Trade Center towers!

Maybe I shouldn't be talking about this...

Asbestos insulation could saved the building and many lives.

I think you're on the right track. I recall some sort of change in insulation materials part way through the construction of the twin towers, because of the EPA, but can't recall any details. A Google search didn't help. Do you have any more details?

Thanks to kimmers for posting the animation site. http://news.uns.purdue.edu/x/2007a/070612HoffmannWTC.html

I read somewhere that the terrorist hit both buildings above the absestos floors.

They were using absestos on the towers before it was banned and once it was they stopped. Thus the first tower was hit higher up.

Federal Building and Fire Safety Investigation of the World Trade Center Disaster Passive Fire Protection by NIST

Several materials were considered for the sprayed thermal insulation. The exterior columns required insulation not only for fire protection but also to control column temperatures under service conditions.Alcoa recommended for the exterior columns the use of a sprayed material produced by U.S. Mineral Products, Co. known as CAFCO BLAZE-SHIELD Type D. The same material was eventually selected for the floor trusses and core beams and columns. This product, however, contained asbestos fibers. On April 13, 1970, New York City issued restrictions on the application of sprayed thermal insulation containing asbestos. The use of CAFCO BLAZE-SHIELD Type D was discontinued in 1970 at the 38th floor of WTC 1. The asbestos-containing material was subsequently encapsulated with a sprayed material that provided a hard coating. A green dye was added to the encapsulating material so that the asbestos containing SFRM could be identified. Thermal protection of the remaining floors of WTC 1 and all of WTC 2 was carried out using CAFCO BLAZE-SHIELD Type DC/F, a product that contained mineral wool (glassy fibers) in place of the crystalline asbestos fibers. On the basis of tests, it was reported that Executive Summary Draft for Public Comment xxxvi NIST NCSTAR 1-6A, WTC Investigation the thermal properties of CAFCO Type DC/F were equal to or “slightly better” than those of CAFCO Type D.

Impressive find.

So what I read wasn’t accurate, thanks.

I am amazed by the information that can be found and authoritatively verified through an Internet search. Asbestos is a bad guy so many media sources write cover stories to keep the bad guy image and exonerate poor political decision making.

My local moonbats are hung up on the other building that fell (Building 5 or 7?).

Yep, that's the one that Rosie is hung up on too. WTC7.

The "little" fact that they leave out is that the main towers blew out the first 10 floors of WTC7 and then WTC7 caught fire and collapsed. The moonbats don't like to discuss that the first 10 floors were blown out with the force of a volcano.
