How did you come up with the 4.2 seconds? Did you start counting from the point when the roofline of the penthouse first started to move, or did you
start your stopwatch at some point after that? If so, Why?
It's timed from the footage in the 9-11eyewitness video and has been timed by other websites and researchers as well, with heights calculated from
the other buildings in the frame. 4.x seconds is the general figure arrived at by all.
A few interior columns failing beforehand causing portions of the penthouse to collapse prior to global collapse does not in any way, shape or form
explain how the entire structure suddenly and simultaneously collapsed at a rate equal to free fall acceleration, most notably in light of the fact
that the exterior columns and composite structure of the building did not show any signs of failure or compression immediately before collapsing. If
you can show that they did, and if you can explain how the intact assembly connections failed simultaneously, in perfect symmetry, and provided zero
resistance to the collapse, then you might just have a case, and you might also revolutionize the demolitions industry. Until then, you'll just have
to keep seeing if skeptics of the official story have written any religious books before and posting your findings in that regard.
