For just you again....
Below is a link to a thread that shows the inward bowing of the outer columns that caused buckling, and initiated the collapse of WTC 2.

So, what evidence and logically argument do you have to outlined what caused the outer columns of WTC 2 to buckle inward in a narrow band around the circumference of the towers relative to jet impacts? Impacts and fires that made it impossible for a CD system to survive?
Drooping floor trusses contracted, pulling in on the outer columns. The bowing became great enough it became buckling. The building above the buckling collapsed into the tower. The falling mass stripped floor connects from the vertical columns. Video clearly shows whole sections of vertical columns standing after the complete collapse of the floor system. The remaining vertical columns shortly toppled because they lost lateral support.
The damage to the floor connections is documented in this:

You really believe those towers came down silently?
Who said anything about paid posters and that the truth movement was created to derail any opinion on what happened that day? I didnt say anything about that... that was you.
Explosives are the only possible explanation, given the evidence.

Evidence ?
Do you mean youtube evidence ?
17 Years and the only evidence comes from chopped together YT clips ?
This conspiracy has spun its wheels for 17 years and gone nowhere.

Are you describing the official story? Then you agree with the commission when it noted 63 times that "we found no evidence" to support various claims of that story?
If so, we agree completely. The public was hoodwinked with false claims.

Quote where I said the steel failed. Outer columns buckled because of bowing because of drooping floor stresses contraction.
Thats wack! Because every degree steel heats up, it increasingly looses its ability to hold up load.
The long floor tresses with no mid span concrete supports made the towers more vulnerable.
Does steel not expand when heated too?
Why does your believe involve ignoring simple truths?
The composition of WTC floor trusses...
ws680.nist.gov...
As shown in Figure 5, each tenant floor consisted of 102 mm (4 in) thick, lightweight cast-in-place concrete on a fluted steel deck. Supporting the slab was a grid of lightweight steel bar trusses.
The lightweight trusses with no mid span supports became deformed from the heat and remaining load. They caused increase side strain upon cooling on the vertical columns the caused bowing and lead to buckling.
They found out fires were not hot enough to cause steel to fail, or lose strength, to cause a failure.
New York City Department of Health concerned about a "dirty bomb" sent health inspector with sensative
radiation detectors to WTC
Within minutes of the crash, McKinney sent a radiological health inspector to check the site for any radiation sources. He reached Richard Borri, a senior scientist in the department’s office of Radiological Health, who like most people from DOH, was on his way to work when the first tower was hit.
“While I was walking down Church Street, with all my instruments, I came within 1000 feet of the South Tower, and unfortunately the building came down,” says Borri, sounding every bit the unruffled scientist. “It’s a good thing I walked slowly.”
Used extremely sensitive equipment
That was fortunately not the case, Borri found, using a portable liquid scintillation counter, which measures radioactivity like a Geiger counter. The high-tech portable gadget he carried, one of the few available in the United States, is far more precise than its century-old cousin, the Geiger, counter with a much more refined ability to detect any kind of radioactivity.
Only radiation at scene was from radio pharmacueticals in pharmacy in WTC
Although Borri didn’t turn up any problematic radioactive readings by the end of the day, his work would be supplemented by the federal Department of Energy, whose technicians remained on site and continued to sample. [Only during the last days of the Ground Zero cleanup would radioactive testers find any evidence of radioactive emissions, from a pharmacy laboratory located within one of the buildings.]

Later that day FDNY HAZ MAT unit carried out surveys - once off duty members assembled, original crew
was killed in collapse
At this point it was utter chaos trying to find people and get organized. It took a while to re-organize and find some people and get working on the rubble to look for survivors. A total recall was ordered and upon the arrival of a few more Haz-Mat guys we performed quick surveys of the perimeter in two teams of four checking for radiation, nerve and blister agent, all results were negative. We then began digging for survivors.
As can see radiation monitoring was carried out from start of the incident

You didn't even bother to look did you.
Here's proof of testing and failure.
You are a shinning example of parroting the same old conspiracy lines without looking for the truth.
It's the same old BS week after week.
