WTC 7: Sound Evidence for Explosions
In this video, David Chandler examines what may be the sounds of explosions during the destruction of WTC Building 7. The evidence appears compelling and chilling.
Chandler also explains the important point of how NIST sidestepped investigating explosions and explosives by “setting up an artificially high threshold of interest”. He points out that they ignored any testimony or recordings of explosions that would not register 130-140 dB at a one kilometer distance, a criterion that they established 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. Chandler states:
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 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.
It should be noted, however, that care is necessary in advancing scientific evidence via video media since it has been used to insert numerous hoax and erroneous claims time and again in the history of the 9/11 movement.
One example was in 2006, when Rick Siegel made a video called ‘9/11 Eyewitness‘, which claimed to be analyzing sounds of explosions coming from the WTC destruction from across the river. However, the video was found to be advocating a series of nonsense claims:
9/11 Eyewitness is a DVD by Rick Siegel purporting to teach the truth about the attack on the World Trade Center. Instead of elucidating the truth, however, the piece seems designed to hide the reality of the explosive demolition of the Twin Towers by surrounding footage of the demolitions with a verneer of vapid claims and pseudo-scientific analysis. The DVD teaches us that helicopters were instrumental in the Towers’ destruction and that it was a “nuclear attack”.
The analytical work of David Chandler is careful and methodical and in some cases he even reproduces the methods he used. For example, in his analysis of the freefall aspects of the destruction of Building 7, Chandler created a video to respond to critics:
WTC7 in Freefall–No Longer Controversial
The previous analysis of the freefall acceleration was criticized (legitimately) for using a horizontal calibration measurement for analyzing purely vertical motion. Any distortion or stretching of the video could throw off the measurement. In this new video, the calibration utilizes NIST’s data for the heights of the roofline and the 29th floor to do a vertical calibration. The result is a measurement even closer to idealized freefall: 9.88 m/s^2.
