Dear 9/11 Activists,
Please write to the NIST employees in this action. To make this action easier and faster for you, I have included my letter to these employees. Make your letter personal, which you can do by reading the Abstract or the Introduction yourself and choosing certain points from it. Please read and follow Ted Walter's instructions in his email below.
Here is my letter (I've included the title of the paper in the subject line):
Dear NIST Employees,
I'm sure you all will be very interested in this new paper. It is published in the peer-review Journal of 9/11 Studies, which I have attached, and found at this link: https://ic911.org/journal/
According to this new paper, the instantaneous transition to free fall of the entire measurable roofline World Trade Center 7 is conspicuously absent from NIST’s description of the downward motion.
The authors offer a different hypothesis that is consistent with the observed behavior of the collapse of that building.
Please see the Abstract below.
Sincerely,
Frances Shure
Abstract
In its final report on the collapse of World Trade Center Building 7 (WTC 7), the National Institute of Standards and Technology (NIST) described three stages of downward motion in the first several seconds of WTC 7’s descent: a Stage 1 in which the acceleration was less than that of gravity; a Stage 2 in which the building’s north face descended at gravitational acceleration (i.e., in free fall); and a Stage 3 in which the acceleration decreased as the upper portion encountered resistance from below. NIST then claimed that these three stages were consistent with the results of its global collapse analyses. Whereas NIST measured the downward motion by tracking one point near the center of the north face roofline, we measure the downward motion by tracking four points across the entire width of the north face roofline. We also measure the downward motion of two additional points across the entire width of the west face roofline, the only other face that was captured on video. We find that NIST’s Stage 1 mischaracterizes and obscures the true nature of WTC 7’s downward motion. While a point near the center of the north face roofline did begin to experience minimal downward motion at the time NIST labels as “global collapse initiation,” the rest of the north face and west face rooflines remained essentially motionless for about 1.4 seconds. After that, the entire north face and west face rooflines instantaneously transitioned to free fall. This instantaneous transition to free fall of the entire measurable roofline is conspicuously absent from NIST’s description of the downward motion. We then show that the observed behavior is not consistent with NIST’s global collapse analyses and conclude by offering a different hypothesis of the building failure that is consistent with the observed behavior.
