On a smaller scale the Plasco building collapse in Iran reflects the tragedy of 9/11. A tall building collapsed due to fire, killing a large number of firefighters who were heroically trying to rescue people. The physical collapse of the building also reflected many aspects of the collapses both of the World Trade Center towers, and of Building 7. In particular we see the progressive collapse of floors stripping away the support from the walls which then collapse. This progressive collapse can be seen as a series of expulsions of smoke, fire and debris from the windows.

They have long claimed that there are several visible indications of controlled demolition in the way the collapses of WTC1, WTC2 and WTC7 looked. Now those same indications have been duplicated in another building they are forced to either admit that those indications were just part of a regular collapse due to fire, or they have to double down and claim that this building also was demolished by explosives in some strange and implausible conspiracy. They chose conspiracy. Today they sent out a fund-raising letter asking people to chip in to cover the $1,850 they spend on a press release urging the Iranian government to look into hidden explosives causing the collapse. http://www.ae911truth.org/images/PD...lease_Plasco_Building_Collapse_01_20_2017.pdf And they list the indicators that are part of the canon of evidence for their 9/11 theory that they think they also see in the Plasco collapse: This is, of course, nonsense. The building very clear collapsed due to a fire - the simplest refutation being that the floors that collapsed were the floors that were on fire, and no sounds of explosive demolition were heard. You can see the building progressively collapse. No explosives were needed. It's clear to just about everyone that this was just a fire. http://www.presstv.com/DetailFa/2017/01/19/506836/Iran-Tehran-fire But for now AE911 is forced to make these increasingly ridiculous claims. While they say in their press release they are not jumping to conclusions, they should be fully aware that when it becomes clear to their supporters that the cause of the Plasco collapse was actually just fire, then significant parts of their claims of evidence for a 9/11 conspiracy will vanish in a puff of smoke. Let us look more closely at the points AE911 raise (most of which are factually correct), and why they are compelled to see them as suspicious. AE911: "The inferno was limited to the upper floors, yet the entire 17 stories came down in just a few seconds" Almost the entire AE911 case (and the Truther narrative in general) is built on an argument from incredulity. The collapse of the WTC towers looked weird. It seemed that it came down "too fast", "through the path of least resistance", and the official explanation "violated Newton's laws of motion". AE911 has gone to great lengths to press their belief that a building cannot collapse from the top down. And yet here we have an example of exactly that. Besides the collapse being due to fire, it was also due to fire at the top of a building and caused the entire building to rapidly collapse. AE911: "the fires were nearly extinguished" Partially true, and yet irrelevant. Just like in all three WTC buildings there were still substantial fires burning, and the fire here (and in WTC7) had been burning for hours, moving through the building, damaging and weakening connections and structural members as it went. In addition some damage can actually occur as the steel cools and contracts. AE911: "thick black smoke—signs of a low temperature, oxygen-starved fire" Thick black smoke is not a sign of an oxygen starved fire. In fact if you pour fuel into a pit and light it on fire, not only will you get thick black smoke, you will also get temperatures high enough to make steel sag and fall. AE911: "The building’s tumultuous fall is then accompanied by thick, energetic, rapidly forming plumes that are reminiscent of what we see in controlled demolitions." By this they mean the cloud of smoke and dust that is kicked up when the building collapse. AE911 used to refer to this as a "pyroclastic flow" and claimed that it was somehow evidence of demolition because they saw it in building that were demolished. But really it's just what happens when a building collapses. There's a lot of dust, and the falling building displaces a lot of air, creating swirling clouds. AE911: "videos we have compiled show what appear to be—and in some cases sound like—explosions emanating from the tower in sequential patterns as it began to crumble." In the 9/11 controlled demolition mythology, a core piece of "evidence" has been "squibs" - small ejections of debris that occurred several floors below the collapse of the exterior. The cause of these has long been obvious - the interior collapse of floors led to rapid compression of the air, and it blew stuff out of windows. That this is happening is readily apparent in the Plasco building, especially in video that AE911 chose to illustrate it. Again, these expulsions of debris are exactly what you would expect from a progressive top-down floor collapse inside the building. In this regard the Plasco collapse more closely resembles WTC1/2 than WTC7. WTC 1 & 2 were top down collapses, so you saw these exact same expulsions. WTC7 was a bottom up collapse, so the expulsions were largely confined to lower floors, not easily visible on the video.
