PDX 9-11 Truth â Portland Oregon David Chandler gives a short explanation of his findings concerning the 9/11 disaster. This is an event upon which waging war, legislation, and taking away our civil liberties have been based. Part of his analysis is here and given in Portland Oregon in an impromptu meeting. The freefall speed of the North Tower collapse he states was impossible without help from some device or explosion or outside force. The building 7 collapse was very close to freefall...such as the speed a rock would fall if you released it. To find out more: http://www.911speakout.org âÂÂThere is ample evidence, from both witnesses and recordings, of explosions associated with the destruction of World Trade Center Building 7 (WTC 7). NIST sidestepped investigating explosions and explosives by setting up an artificially high threshold of interest. They swept aside any testimony or recordings of explosions that would not register 130-140 dB one kilometer away. They established this criterion using RDX (one of the loudest explosives) in a scenario that produced a far higher sound level than other possible uses of explosives to bring down the building. Then they turned around and used sound level as the sole criterion for deciding whether the use of explosives was a credible hypothesis. By this maneuver, they sidestepped investigating the testimony of explosives or possible evidence of explosive residues. This is just one more instance of fraudulent behavior on the part of the NIST investigation of the World Trade Center disaster.â Check out our website: http://www.911speakout.org .
