Some excellent analytical work regarding WTC7 has been recently discovered that holds critical clues to the building's demise.
http://www.mileswmathis.com/wtc.htmlAfter several failed attempts to explain the collapse of World Trade Center Seven, NIST and FEMA have now joined together to release this latest report. In it we find the definitive analysis of the most critical aspects of the collapse, including the final scientific data based on years of investigation and computer modeling.
The full report has been published and it contains some 180 pages, including 20 pages of charts and models. What is offered here is simply a gloss. It is hoped that by reading it the public will at last be satisfied that the case has been solved and that the investigation may now be closed.
The key piece of evidence here is the discovery of janitorial service orders and memoranda stored off premises in computers at the companies hired by Silverstein, Inc., to clean the offices. By studying the documents from the week of September 11, 2001, NIST scientists made the shocking discovery that toilet paper dispensers in WTC 7 had been filled beyond capacity the morning in question. Not only that, but interviews with cleaning personal that had been on duty that morning indicate that many excess rolls had been stored in basement supply rooms, broom closets, and even (at times) in the stalls themselves
