9/11 - Building 7's Collapse

A third tower in New York collapsed on 9/11, later on in the afternoon.  Like the twin towers, this building falls uniformly and at free fall, indicating a complete and simultaneous failure on all 24 core columns at once.  If fire were to blame, the timing difference between core column failures would be immense, and the building would collapse one section at a time and very unevenly.  What's really happening here is the melting through 24 thick steel columns at precisely the same time.  This is beyond the shadow of a doubt a controlled demolition.
