I ran across a great picture of the Windsor Tower conflagration and posted it side by side with the image from 9/11 of a woman standing in the dark hole in the WTC made by the plane.

The Windsor fire raged out of control for 28 hours, while both WTC towers "collapsed" in less than 2 hours.

Good link for friends who try to tell you that the fires weakened the steel and initiated the collapse.
