    Physics Instructor David Chandler gives NIST another whack with the ruler

    There are several outstanding leaders in the 9/11 truth movement. High school and community college physics instructor David Chandler has found his place among them. With 30 years of experience teaching physics, math, and astronomy in a variety of schools in the US and India, Chandler easily guides the layperson through the basic physics of 9/11. His articulate, detailed website, co-produced with AE911Truth’s Jon Cole, another prominent contributor to our mission, provides valuable documentation of the controlled demolition of all three WTC skyscrapers. For instance, he has produced a premier article on Building 7 which he says presents physics at the level of “the first month of a high school physics course” in a Resistance Radio interview with Tod Fletcher. The NIST report on Building 7 is inconsistent with basic physics as we know it. Chandler notes “if the NIST report on Building 7 had been turned in by a first-year student in one of my classes, it would have received a D or an F.” Its 1,000 pages of error, negligence, and fraud are exposed by Chandler’s simple, historic papers and videos.

    Chandler has just released a new DVD which is a well-edited compilation of his many videos that spells out in no uncertain terms some of the physically impossible and obviously false features of the official explanation for what transpired on 9/11, as they relate to the Twin Towers and WTC 7.

    This DVD is now for sale in the AE911Truth online store.

    WTC Building 7 in Free-fall

    NIST, when confronted publicly with evidence produced by Chandler, finally admitted in their November 2008 Final Report that WTC 7 fell for 2.25 seconds in free-fall, but they brushed off this newly acknowledged fact as being “consistent with the results of the global collapse analysis,” despite Sunder’s earlier statement. Thus, the NIST simulation and analysis represented a multi-million-dollar effort to avoid explaining what really happened.

    Many other physics analyses are presented by Chandler on his website 911SpeakOut.org, applying the laws of physics to WTC 7 and the Twin Towers. For a more detailed account of the unexplained features of the destruction of WTC Building 7, see the article on page 1.

    The North Tower’s Destruction: Race with Gravity

    Video evidence shows constant acceleration down of WTC 1 roof

    Using measurements from network television videos, Chandler was able to show that a series of what he describes as “demolition waves” travels down the side of the North Tower (WTC 1) even faster, at times, than the debris falling through air outside the Tower. This officially unexplained phenomenon can be seen in the video clips, Race with Gravity, and more recently Acceleration + Serendipity, at Chandler’s website. Either something is moving through the building as fast as the debris is falling through air, or what we are seeing is a wave of timed explosions. This wave of ejections is the fastest-moving feature of the collapse, racing far ahead of the overall building collapse.

    “North Tower Exploding”

    Steel frame members ejected horizontally, some at speeds exceeding 70 mph

    Incredibly, NIST took its analysis of the destruction of the North Tower (WTC 1) only to the point in time when the building started to collapse. The visual evidence therefore was omitted from their analysis and Final Report. Yet it reveals the most critical features of the tower's explosive destruction that can clearly be seen by anyone. Chandler shows in the video North Tower Exploding a series of widespread, continuous, explosive ejections of material occurring on multiple floors at once. Individual steel frame members weighing many tons are ejected horizontally, some at speeds exceeding 70 mph. Some steel members traveled horizontal distances of 600 feet. Others embedded themselves in the walls of neighboring buildings.

    The top section of the building, above the airplane impact point, is what NIST claimed crushed the rest of the building to the ground. But the top section is seen being destroyed in the first 4 seconds. And after that there is no visual evidence of anything crushing the building. The building is seen tearing itself apart – and, as Chandler documents in his next video, at an incredible rate approaching free-fall.

    Downward Acceleration of the North Tower

    Chandler clearly demonstrates in “Downward Acceleration of the North Tower” on his website that the top section of the North Tower (WTC 1) accelerated down at a constant rate which equaled about 2/3 of free-fall. Using basic physics he notes that the fact that the top section continued to accelerate downward proves that the top section was not exerting enough force to destroy the lower section of the building. Rather, it was the destruction of the lower section by other means that allowed the top section to continue to accelerate. This is again strong evidence for the use of explosives.

    Be sure to see the rest of these excellent videos in the new DVD, including Cutter Charges in the North Tower of the World Trade Center, which shows how Chandler was able to link two “puffs” to an actual column being cut. These are striking examples which use high school physics to provide a devastating challenge to the official conspiracy theory.
