I always find Chandler's videos to be simple, direct and convincing.

YES!
Can't say enough about the contribution that AE911T has made to the movement so far, and not just Richard Gage, but people we may never have heard of like David Chandler, whose work as shown in the vid you posted above is extremely compelling and excellent for showing to newbies...
David Chandler's videos "removed by user"?
I hope they go back up--if not, I hope Chandler is planning to make them otherwise available online...

DavidChandler911 — April 27, 2010 — I have revisited and extended some of my early measurements of high speed massive projectiles from the World Trade Center on 9/11. The results for the three projectiles measured: 56 mi/hr, 45 mi/hr, and 78 mi/hr. I don't claim this is smoking-gun evidence of explosive demolition all by itself, but it is part of the puzzle and it is more compatible with the explosive demolition hypothesis than simple gravitational collapse.
(On a technical note, if you are looking at the numbers in the three measurements, the third measurement is taken while the video was zoomed in, relative to the calibration frame. The numbers shown have to be scaled down by a factor of 1.701 to give the stated results.)

WTC 7: Sound Evidence for Explosions
DavidChandler911 | July 05, 2010
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.
