After Northtower was hit a big chunk of papers were released from the south tower. Is there any reason or explanation to this phenomenon?
Was it some kind of mechanical ejection mechanism on the outside of the side face of the south tower that released plenty of paper batches all at once?
When someone throws a bunch of papers in the air, only after a few seconds they get spatialy distributed. In this scene we have a miniversion / one window only version of a bunch of papers flying through the air. Is the occurence really random or are even the papers only a part of decoration to make the scene appear more chaotic?
