WTC 7 Sound Evidence and NIST coverup

July 05, 2010
New analysis by David Chandler on the sound evidence of WTC7 explosions. There 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.
