ABSTRACT

 

In writing this paper, I call for a serious investigation of the hypothesis that WTC 7 and the Twin Towers were brought down, not just by damage and fires, but through the use of pre-positioned explosives.  I consider the official FEMA, NIST, and 9-11 Commission reports that fires plus damage alone caused complete collapses of all three buildings.  And I present evidence for the explosive-demolition hypothesis, which is suggested by the available data, testable and falsifiable, and yet has not been analyzed in any of the reports funded by the US government.

 

 

Let’s start with the collapse of the 47-story WTC 7, which was never hit by a jet.  I ask you to take a minute to look at the collapse of this building as a basis for discussion.

 

 

       

  WTC 7: 47 - Story, steel-frame building..
 

        

            WTC 7 on afternoon of 9-11-01.  WTC 7 is the tall

     sky-scraper in the back-ground, right.  Seen from WTC 1 area.

 

   

            WTC 7 collapsed completely, onto its own footprint

 

                                                                                                 

Now that you have seen the still photographs, it is important to the discussion which follows for you to observe video clips of the collapse of this building, so go to: 

 

http://911research.wtc7.net/talks/wtc/videos.html    Click on the three photos at the top of this web-site page in order to see the videos of the collapse of WTC 7.  It helps to have sound.

 

Then consider a video close-up of the same building (SW corner) as its demise begins:

What did you observe? 

Symmetry: did the building collapse straight down (nearly symmetrically) – or did it topple over?

Speed:  How fast did the building fall?  (Students and I measure less than 6.6 seconds; time it!)

Smoke/debris-jets:  Did you observe puffs of smoke/debris coming out of the building?  Please note for yourself the sequence and fast timing of observed puffs or “squibs.â€
