I have spent considerable time going through these short video clips since I saw them again and Gemma brought them up on her show, because they have so many obvious things wrong with them. This NIST FOIA WABC Dub 1 42 shows;
1. A minimum of 4 different people using fake smoke obscurants, probably single use battery powered foggers, wands. 2 of which are seen in these two videos below placing these fake smoke wands onto the buildings facade. Make sure you enlarge video and pay attention to the far right as well.
2. One person is out of the window past his center of gravity. What's keeping him from falling? He is seen placing this portable hand held smoke obscurant onto the towers exterior beam and then playing with the smoke as it comes out of the nozzle end. The 2nd video which also has a clip of this shows much more then the 34 second video and is much clearer. That's the video where you can clearly see the 2 people place the fake smoke foggers onto the towers exterior, which isn't clear in the 34 second video.
3. The windows are not the right size windows. People have argued this is a perspective issue from where the video was shot from a downward angle, but it's not a perspective issue.
4. The first video, the 34 second NIST release shows what some called an explosion or a shock wave working its way up the towers left side at the very beginning of the video. Watch for it. The windows appear to have shutters on them which are light on one side and dark on the other, and they open and close very quickly. Your going to need to slow it down to .25 speed and watch it a bunch of times to see it and observe it.
The second video to see the relevant section is marked to start at 4:35 and end and 4:59. Notice the two people on the same level, but one of far left and the other far right how they place the hand held smoke foggers/obscurants onto the towers beams. The guy on the left @ 4:57-4:59 in the video below. And a person on the same level to the far right does it between 21 and 27 second mark. Watch at different speeds but make sure to drop it down to .25 speed on both. I also think the girl at the very beginning of the 2nd clip who is waving a towel or table cloth out the window is wearing some sort of safety harness.
