Why AlienEntity's Measurements Continue to Misrepresent WTC7's Fall Rate

Debunker and JREFer AlienEntity recently uploaded a video which supposedly shows that his "independent measurements of the collapse of WTC 7 corroberate NIST."



Yes, his video certainly seems to defend NIST's distortions of the truth quite nicely.

We may observe that AlienEntity, like so many other debunkers before him, has once again failed to address the 2.25 second free-fall drop that the building exhibited. But even that aside, is AlienEntity's point even valid to begin with? No. Below is a video I made around three months ago dealing with this very topic. You may decide for yourself which one of our measurements has more validity.



While it is true that the building did start moving at the beginning of NIST's timing, it is clear that the west side of the building did not start to fall until 1.5 seconds into that timing. This was in fact the issue that was presented to NIST when scientists, scholars, architects and engineers responded to them:

The frames we used in our collapse analysis are shown below (times “t + X seconds” reference the times given in NIST’s Appendix L, Table L-1) along with a graphical analysis of how we determined which frame represented the onset of global collapse:






To start the timing at the point where NIST chose seems unjustified. To quote David Chandler:

I'm sure they detected some movement of the roofline at the point where they started the clock as a rationale for choosing that point. Even our data here shows a tiny amount of motion in the first second. But what was going on during this time is qualitatively different from what happened moments later. The event triggering the start of their measurement could more accurately be described as precursor movment.


Indeed, this sort of "precursor movement" is seen happening in many controlled demolitions.



But let's say for the sake of argument that AlienEntity and NIST are right, and that the fall was ultimately 40% longer than free-fall. If this were true, then the overall fall time of the building would have been around 7.5 seconds. Should the building have fallen even that fast? From what we know about other demolished buildings, I'd say no.



It is obvious that while AlienEntity continues to endorse NIST's "Bush Science," at the same time he also continues to help NIST further distort the truth about why Building 7 really collapsed.
