Great post reel.deal !

I've also been working on the WTC collapse-imagery today. Here you go:
************************************************************************************************************************************************
THE SWAYING ANTENNA(Note: all dotted lines are vertically aligned/parallel with the body of the WTC building)
Pictures 1-2-3 are frames from a video credited to one “Etienne Sauret”, a French filmmaker who allegedly roamed around Manhattan filming the morning’s events. It is a quite steady shot, seemingly filmed with a tripod-mounted camera. At no time in the clip do we see the WTC antenna leaning West: as the collapse starts, it gently comes straight down and then tilts/falls progressively Eastwards. 1-2-3.
Picture A is a frame from an anonymous ‘Camera Planet’ video (from Steven Rosenbaum’s perp archive). It is a very jerky, seemingly hand-held shot, and the full antenna is only briefly framed such as in this split-second instant (A). I’ve applied a red-scale filter to it for the purpose of this analysis - just to distinguish it from the Sauret sequence. This antenna clearly tilts Westwards.
The very first observation we may do here is that PictureA and Picture1 appear to represent the exact same moment in time. We can verify that by comparing the smoke patterns. This moment occurs within 1 second of the start of the WTC1 collapse. Admittedly, the full height of the antenna is not shown in Sauret’s shot. Yet, if you have a chance to watch the full Sauret video, you will notice that the antenna, (from its perfectly vertical pre-collapse position) never sways in any direction in the first few seconds of the collapse; it then proceeds to tilt Eastwards decisively, and disappears in the smoke.
Before we go any further, let us look at the (slightly different) perspectives of these 2 videos: to be perfectly honest, I have not been able to identify the (apparently identical) building seen at left of both shots. However, given the exceptional height of the WTC towers in relation to other NYC buildings, what we see here appears optically absurd. Where are these 2 cameramen located? Are these views even possible from any existing vantage point in Manhattan, however distant from the WTC? In any case, no existing zoom lens can focus a nearby building as sharply as a distant one.
And the final question is: how can the antenna be tilting West in Picture A? To be sure, and as long as we trust Isaac Newton, we may raise fundamental questions as to the physics of this occurrence: can a pencil placed upright on a milk carton sway first right – then left - if the milk carton collapses? How about a 110m tall antenna?
