"Looking at the upper right-hand corner of [WTC7] we see a rapid series of small explosions travelling upward just as the building itself begins to fall. The size, placement and timing of these "puffs" is very consistent with squibs from cutting charges of the type used in professional controlled demolitions..."
Looks very convincing, doesn’t it? But under closer examination this claim doesn’t seem quite so robust, and we have concerns in four different areas.
#1, how was this image produced? “Enhancing” video footage is a very subjective business, making it wise to compare pictures like this with the source material. Click here to see why.
#2, when did the “squibs” really appear? The claim above doesn’t say exactly, and for good reason. Look at the original footage and you can see the building is falling for some time before they pop up. Here are the images.
#3, everyone who writes about this makes it seem like these images could only be produced from explosives. Look at the video, though, and you’ll see the building deform, causing windows to break, just as the “squibs” appear. So how do we know they weren’t caused in a similar way? Take a look for yourself.
And #4, presumably these “squibs” are supposed to be throwing smoke and material out of the windows. So why is it that the video shows the “squibs” staying in more or less the same place relative to the building, even as it’s falling? It looks like there’s more smoke ejected from regular broken windows than these supposed demolition charges. Here are the stills.
Put it all together, then, and the “squibs” appear after WTC7 has begun to fall, as floors sag across the building, and at almost exactly the same time as this effect causes other windows to break. As these also appear to eject more material than the “squibs”, then the most plausible explanation is they’re nothing more than windows breaking as the building falls.
