In most people's minds, the World Trade Center (WTC) was two giant towers that crashed into gravel after they were each hit by a jet on September 11, 2001. Fewer people know that the center actually consisted of seven buildings around a peat. The seventh of these buildings was half as tall as the twin towers but, after all, projected nearly 200 meters up by its 47 floors and covered a plot of land slightly smaller than a football field.

Even fewer people know that this building collapsed in the late afternoon, seven hours after the collapse of the towers. Building 7 was not hit by any aircraft.

The lecture deals solely with the technical and physical circumstances of this event, which must be called the most unexpected and inexplicable collapse of the history of modern architecture.

In the first part, accounted for the official explanation of the crash, as presented in a report from the National Institute of Standards and Technology, September, 2008. This compares with some simple observations and Newton's laws.

In the second part, the collapse of the two twin towers is involved. A revised hypothesis is presented, supported by technical documentation - including the latest discoveries.

There is time for discussion.

The lecture will be held in Danish.
