The discussion is indeed over. You failed to provide proof that puffs can only happen in controlled demolitions. It is basically a baseless assertion you make. Not sure what it is doing in a thread about "911 The facts and the proof only."

You can't possibly be serious about this. First of all, you switch the subject altogether. And secondly, it is utterly impossible to make an analysis like this with such a lousy highly compressed low res image. More truther "facts" and "proof".

The top 15 stories of the north tower had to be lighter and weaker than the bottom 90 stories. So it is absurd to think the top 15 stories could crush the bottom 90 in less than 18 seconds. That is where the conservation of momentum and strength of materials comes into this issue.

S&F because I believe what my eyes tell me and not the TV.
Half the plane has melted into the building before any hole has even appeared!! This is of course impossible in real life, where immediately upon impact, a hugh fireball should be observed,
I has been explained many times, and very likely to you too. There is no conservation of momentum in the building collapses. There is a constant increase in momentum, resulting in increasing impact forces, resulting in an accelerating collapse. This statement is true with our without demolition charges.

And guess what? Nothing but dust at the bottom. A pancake collapse will leave the top section mostly intact while crushing the lower section. This didn't happen. Instead, core steel beams were ejected hundreds of feet outwards, and almost the entire concrete structure was turned to dust.
According to your physics explanation, the only way for that to work in the world of our reality, is if any resistance from the bottom chunk of the building disappears, meaning it's core beams are cut, and gravity pushes the collapse.
Groupthink is a psychological phenomenon that occurs within groups of people. Group members try to minimize conflict and reach a consensus decision without critical evaluation of alternative ideas or viewpoints. Antecedent factors such as group cohesiveness, structural faults, and situational context play into the likelihood of whether or not groupthink will impact the decision-making process.
The primary socially negative cost of groupthink is the loss of individual creativity, uniqueness, and independent thinking. While this often causes groupthink to be portrayed in a negative light, because it can suppress independent thought, groupthink under certain contexts can also help expedite decisions and improve efficiency. As a social science model, groupthink has an enormous reach and influences literature in the fields of communications, political science, social psychology, management, organizational theory, and information technology.
The majority of the initial research on groupthink was performed by Irving Janis, a research psychologist from Yale University. His original definition of the term was, “A mode of thinking that people engage in when they are deeply involved in a cohesive ingroup, when the members' strivings for unanimity override their motivation to realistically appraise alternative courses of action” (Janis, 1972). Since Janis’s work, other studies have attempted to reformulate his groupthink model. 'T Hart (1998)  developed a concept of groupthink as “collective optimism and collective avoidance,” while McCauley (1989)  pointed to the impact of conformity and compliance pressures .
Proof for either of these "facts"? I think both are completely false.
“nearly all of the non-metallic constituents of the towers were pulverized into fine power.” That observation was also made by Colonel John O’Dowd of the U.S. Army Corps of Engineers. “At the World Trade Center sites,” he told the History Channel, “it seemed like everything was pulverized” (History Channel, 2002).
In the case of the Twin Towers, photos and videos reveal that “[h]eavy pieces of steel were ejected in all directions for distances up to 500 feet, while aluminum cladding was blown up to 700 feet away from the towers” (Paul and Hoffman, 2004, p. 7). But gravitational energy is, of course, vertical, so it cannot even begin to explain these horizontal ejections.
No, that is not the only way for it to work. That is you being ignorant at figuring out an alternative way for it to work. Or in other words, you are making an argument from ignorance. That does not really belong in a thread about facts and the proof only.
“The smart way to keep people passive and obedient is to strictly limit the spectrum of acceptable opinion, but allow very lively debate within that spectrum — even encourage the more critical and dissident views. That gives people the sense that there’s free thinking going on, while all the time the presuppositions of the system are being reinforced by the limits put on the range of the debate.”
