But you can see in that photo you posted that the smoke is coming out of the windows of WTC7, not "building up" from a lower source. You can see this even better in the videos that those stills are from. Another weakness in your argument is that your quote talks about how the smoke is periodically swept away, but we don't see that with WTC7.Quote:
In a wind-tunnel study, recorded video images of smoke dispersion in the wake of a rectangular-shaped building were analyzed.^A continuous source of smoke was emitted at floor level, midway along the leeward side of the building.^Smoke was observed to build up within a region adjacent to the building.^Then the smoke was periodically swept away by vortices shed from the leeward building sides and roof.^
You do have a good point about the flames not being visible from photos of its North side. Maybe the windows were coated with soot, maybe the air in the building was too opaque to let the light through, maybe the fires were actually contained to the lower floors and the smoke filled the building, coming out all the South windows broken by the North Tower collapse. Even that last explanation, which I think you may agree with, is perfectly consistent with the standard model of WTC7's collapse.
