David Chandler on WTC 7: Sound Evidence for Explosions
The video shown here is the latest in the series. It is a result of collaboration between David Chandler and Debora Blake, who contributed some of the visuals and did the video editing:
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 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.
WTC7 in Freefall--No Longer Controversial
This is a revised analysis of WTC7 freefall collapse by David Chandler a High School Physics teacher. He has included an analysis evaluating the claims made by NIST in their Final Report of WTC7. However, what is most compelling about this video analysis is the pure, unbiased scientific scrutiny that David gives to the collapse.
He is truly "spot on" with his application of the universally applicable law of free fall bodies due to the acceleration of gravity.
After any open-minded, logical person views and comprehends what they watch in this video, there can be no doubt that that building came down at virtual free-fall speed...which raises the question, how could that be? The only reasonable answer is via controlled demolition...and that raises the question how could that be pulled off on the very same day "a surprise attack" was perpetrated on the US.
After all, controlled demolitions take weeks and weeks of planning and coordination to put in place and test.
A whole series of questions then follows...Could Arab terrorists have access to this building or the twin towers? If not then who? All unanswered questions, that to date have no good answers...that the 911 commission report failed to uncover or even discuss.
Please watch this video and pass it along to other technically-inclined and savvy folks. Thanks to ae911truth.org for making this available.
Cutter Charges in the North Tower of the WTC
By David Chandler
This project began with an email from Graeme MacQueen to me describing an explosion on the NW corner of WTC1.
I started looking for other such explosions and found a prominent one right at the initiation point on the 98th floor. I further noticed a corner column sticking up after the roofline had fallen past. The top of the surviving column matched the height of the corner ejection moments before. This seemed to be the event that cut the column. The column hovered and swayed for several seconds then precipitously dropped. I wondered if Graeme's explosion was the one that triggered the drop. I found a way to synchronize the videos and then was able to verify that Graeme's "puff" occurred exactly at the moment of drop of the column.
The main significant points I see in this observation are:
1) The building is doing more than just blowing smoke out the windows. The puffs we see are part of the cause of the collapse.
2) We are seeing charges that can cut through the steel corners of the buildings
3) We are seeing a specific 14" column cut by explosives in two places: one to set it loose, and one to cause it to drop.
4) The two explosions occur in a time-delayed sequence, indicative of demolition
(Tony Szamboti and Carolyn Chandler, also made observations that contributed toward this video. All are acknowledged in a credits screen before the closing logo.)
