Suddenly, about 6.5 seconds into this clip, towards the left of the frame, by the SE corner, a row of windows are simultaneously pierced by violent puffs of dark smoke. But at the same instant, evidence of explosion(s?) can be seen towards the right of the frame, by the NW corner of the tower, more than 250 feet away.
Right away, the tower's east face is illuminated by the oversized(cached) South Tower (WTC 2) fireball.
So that's at least 2 "coincidences" within 1 second of each other.
In the instant after that, the row of puffs of dark smoke re-emerge (even though the surrounding 2 columns of escaping dark smoke, which had previously been seen above the puffs, still have not).
Then the video feed goes blank for 4 seconds, and then an unidentified man (if you know who he is, please tell us) appears on-screen before the original interview video is restored. 9/11, it seems, was full of anomalies...
The soundtrack then corroborates the fact that the 'collapses' were subsequent to explosions in the form of the reporter's question to Port Authority Inspector Gene Ceccarelli ("crashes, then the explosions, and then the 'collapses'"), to which the Inspector breathes deeply but does not dissent.
So, on 9/11, NBC broadcast television network aired some video which makes it possible to see that perhaps something other than airliners was responsible for making the nearly-airliner-shaped holes in the tower walls. Does this indicate that the towers contained some kind of synchronized network of explosives, which detonated upon 'impact' (with the other tower!)? (If we never ask the right questions, how will we ever get the right answers?) This video, and the one below, is yet more evidence that, by having failed to even include the word "explosions", the 9-11 Commission Report did not tell us the full true story of 9/11.
