I’m telling you that neither you nor I can judge the strength — tensile, torsional, compressional — of a material from a photograph. Can you look at a piece of metal in 50 year old photo and tell me if it is aluminum, magnesium, iron, steel or hardended steel? Of course you can’t. And yes, you are incorrect about the load bearing design of WTC 1 and 2. Wind shear is of course different to sudden impact. The point was that you are incorrect about the load bearing design of the WTC 1 and 2 exoskeletons, among several other things.
Yes, we saw the buildings pancake. Something that is not reproducible either using finite analysis and/or NIST documentation and/or reproductions based upon “only” an airplane crashing into WTC 1 or 2 (or no airplane at all for WTC 7). That’s the fucking point. The NIST report cannot be reproduced either in practice or in theory — because it is wrong.
For a building to fall in freefall (as we saw with WTC 7 and nearly in WTC 1 and 2) then the vertical supports must be completely compromised. An airplane hitting floors 77–85 of a building does not completely compromise the vertical supports of the floors above or below (or even floors 77–86 of WTC 1 or 2). Therefore “pancaking” i.e. “freefall compression” CANNOT happen by itself. It just can’t. It never has before. It never has since. It cannot be reproduced by the NIST math. It cannot be produced in controlled recreations. ERGO: The NIST report is wrong.
This is not just a matter of proving NIST wrong and showing a conspiracy. Engineers and architects have to sign off on our designs. If we sign off that something can’t happen and then it does, we may be legally liable for damages. So if an airplane can bring down buildings like WTC 1 and 2 that were designed to easily survive such a situation, it really fucking matters to engineers and architects designing similar buildings in the future. The fact that we cannot reproduce the results of the destruction using NIST’s math creates a legal and professional problem: How do you design for something that is impossible but NIST said happened but refuses to back up? How much different — and more expensive — do you have to design a future building?
