The first Tower to collapse was the south tower.
It Conveniently leaned sideways , avoiding hitting the north tower, and possible exposing explosives placed in the north tower.

After viewing several close up videos of the south tower collapse.Multiple Straight lines of flashes can be seen travelling in sequence across the face of the building.

What seems to have happened is nanothermite cutter charges were used to cut core columns.Before and during the collapse.
A slower reacting thermite was used on the edge of the south tower ,the reason for using a slower reacting thermite was to give the impression of a gravity driven collapse.
When really it was a gravity ASSISTED collapse.
It looks like the south tower caved in onto itself.After the molten steel melted the area around it.

Multiple angles should rule out light reflections.
Paper does not travel that fast and i do not see a reason for falling reflecting objects to fall at a perfect 45 degree angle.
