as written at https://www.septemberclues.org/power_of_imagery.shtml."Thus, in all probability, the oldest trick in the manuals of covert military ops was used: smokescreens. ...In reality, the towers were most likely enveloped in thick smoke (military obscurants) as they collapsed - and no real footage exists of that brief event."
A question would follow: If there is no existing "authentic" footage (photography or videography), then what is the evidence that a smokescreen was deployed?
Is it the testimony of many alleged observers who commented on the smoke? How can the reliabilty of those reports be determined, if there were allegedly many actors as carefully transmitted by well-controlled media?
Is there some kind of well-defined collection of "authentic, non-controlled, organic, first-person reports" from that fateful date? This would consist of people either going about their day, then evacuating (or not), or something like that, for the most part, presumably. Maybe oral testimony. Maybe some film photography. It might be surprising if in 2001 if there was no authentic amateur 35mm film photography of such an amazing and somewhat long-lasting spectacle, but maybe that is possible, especially if there were official, authoritative efforts to collect any and all examples of such of artifacts, for the greater good.
Throughout FAKO 940-949, the host, Ab Iratio, seemed to stick to a position that zero authentic footage remains. Maybe. If so, what evidence exists of the smokescreen that went up? Is it simply a logically arrived at conclusion at this point?
On this topic: In FAC1467, a speaker, Misom, recounted having seen smoke clouds on European (German) television (on, or perhaps shortly after, 9/11), and asked if these could have captured and shown such a Total Smoke Screen, the implication being that perhaps a European outlet could have accessed a video source other than the posited centrally-controlled single source. These recounted moving pictures, too, Ab Iratio suggest would have been just another inconsistent conjured set of media in the pile of contrived imagery. How exactly exactly did that German footage appear; is it archived online? An immediate review of the TV archives does not show such footage, but maybe it is somewhere.
