Now it's my understanding that in a controled demolition a prep team cuts about 90% through support beams and the explosives do the rest.

So for a WTC thermite conspiracy....

1. Would a thermite torch be used to pre-cut the support beams in the weeks leaving up to 9/11?
2. Or....would these thermite torches have been used by the perps ON 9/11? If so, wouldn't the thermite perps have been killed too?

US published application 20060266204 seems to indicate that less prep work would be needed for a thermite charge than a traditional explosive:

[0006] This thermite-based method will allow operators to penetrate a material in timeframes similar to explosive shape charges without the safety concerns and security risks associated with explosives. In addition, the sustained duration of a thermite jet will more effectively handle discontinuities and interfaces that normally disrupt and dissipate explosively driven shape charge jets. When a linear shaped charge is used for cutting steel on a steel bridge demolition project, a large degree of preparation work must be undertaken to ensure a successful cut or penetration. A "preconditioning" process involves removing overlapped plates and areas of reinforcement with a conventional cutting torch. This process is time consuming, expensive, and dangerous. Conversely, the sustained jet of a thermite charge offers improved performance over multi-plate materials with limited or substantially no preconditioning. The thermite charge's sustained jet also affords a greater assurance in cutting plates of varying thickness, layered plate configurations, and any supporting or reinforcing members that may exist in the middle or on the backside of a material. While the projected thermite charge particle stream is a slower reaction than that of an explosively driven jet, it is very fast from the perspective of the operator. The anticipated timing for material penetration is typically on the order of hundreds of milliseconds.

But of course, this application wasn't filed until Mar. 8, 2005, so it's a bit late to be using it on the WTC.

They also list some preferred uses:

[0061] Applications for the invention include linear cut or curvilinear cuts in homogenous and non-homogeneous materials. Typical cutting operations include: Concrete, and reinforced concrete, in a variety of applications (cut into slabs or rubble); break pavement for a variety of access needs including utilities: gas, electric, phone, cable, water, sewer; street applications including bridge decks and other repair/replacement; road beds in large scale--highway with rebar; concrete in any structure (walls, etc.); demolition--of structures, buildings--steel reinforcing (I-beams in concrete); steel bridges, steel hulls (ships for rescue applications and hostile applications); and general concrete removal.

So it isn't clear that it will cut large steel columns - how big would I-beam in concrete or steel ship hulls be? If it can cut large steel beams or columns, it seems odd they wouldn't list it here.

I wonder how many core columns would have to have been pre-cut and on how many floors.

Not just the core columns. 28k believes the core on it's own can hold the entire upper mass with the outer columns buckled. Part of why he thinks the NIST is wrong.

So if he believes this, then he has to show that the outer columns can't hold the upper mass with the core columns cut. Given that there are over 200 outer columns vs the remaining 37 core columns, that will be tough.
