The collapses of the Twin Towers in Manhattan on September 11th are known to almost everyone.

The total collapse of a third skyscraper that day remains virtually unknown.

WTC Building 7, a 47-story steel skyscraper, plunged into its footprint at 5:20 PM.

Slick science TV programs "explained" the collapses of the Twin Towers.

Building 7's collapse, so far, has required no such PR campaign.
