freefall speed of collapse, 3x. yeah, 10 seconds quarter mile high to hit the ground (ZERO resistance from existing massive steel columns)....
I'm confused. what are you saying here?
the towers were designed to withstand impacts from 2 or 3 707 jets simultaneously. (there are 4 engines on a 707)
they
are were supported by 200 vertical steel columns around the perimeter, and several massive core columns that rise from the foundation to the roof.
on the day, it was as if they did not even exist, as the buildings fell at freefall speed (32 feet per second squared) the roofs meeting the ground in just ten seconds
there was zero resistance from these supporting columns, which means that incindiarys and explosives had to be used to accomplish such a quick fall
Anyway, as I remember that day multiple TV channels were reporting about building 7, that it had been on fire, that it was likely to collapse or about to collapse. Can't remember the exact words, but the point was it was common knowledge because half of one side was tilting over and the top had caved in.
that's not true at all. watch it again. there were some fires, some incidental damage, the building evacuated. just before the collapse the rooftop can be seen to dip, as the core columns were cut using incindiarys and explosives
it might have been common knowledge locally, because of all the loud explosions heard and reported by many witnesses
jet fuel (kerosine) does not burn hot enough to melt steel. no steel framed building has ever collapsed from a fire
The herd of people matches the lemming story better than the story ever matched the lemmings.
