Has anyone commented on this video simulating the Flight 11 path through the North Tower structural columns? Of course this really does not account for the demolition wave progressing down the tower ahead of the collapsing floors.

Quite an interesting video, although I doubt that thin aluminum can slice through heavy structural steel quite so easily. I hope this is something new which will likely produce some interesting feedback from you guys.
