“All controlled demolitions use explosives that are carefully sequenced and create extremely loud noise when they detonate. They also produce spikes of energy that would be recorded by seismographs.” … “Each of these factors is missing [in the body of evidence pertaining to 9/11].”
It is completely untrue to say these factors are missing from the evidence. There is abundant evidence including audio, video and seismic recordings, which clearly show evidence of explosives during the destruction of the towers.
The following video is quite long (about 1 hour) but it is very revealing and educational.
Following a very brief introduction by Niels Harrit about the NIST findings, there are sections showing clear evidence of sequenced explosives in the North Tower collapse, plus upward and outward explosive ejection of heavy building components being hurled sideways hundreds of feet.
One video section (which has been carefully adjusted to compensate for the distance of the camera from the towers, so that sound and vision are synchronised) shows massive explosions at the base of the towers well before the collapse starts, as well as other large and sequenced explosions in the run up to and during the collapses.
Another section shows clearly, using high school physics (with easy to follow animations), how the observed ejections of heavy steel beams and other material cannot follow the outward and upward trajectories they did except by explosive forces.
There is a section which analyses FEMA’s own seismic recordings which show the very large energies at work during the collapse of the towers, and how these recorded energies do not match the potential energy of the buildings. They also show how the recorded seismic energy of both towers are very different from each other (one almost double the other), despite both buildings being substantially the same and therefore having very similar potential energies.
There is much to see here for anyone with an open mind who wants to see actual evidence that explosives were used.
