When they started saying the towers "should have been made with a concrete core" is when I knew that this lie was very important to expose.
My impression of the public controversy is that if we stick with the raw evidence of images, we are less vulnerable to confusion.
This image,
should show many columns in the core area, through the stairwells, to the right and left of them. None are shown where
FEMA places them. It clinches it, done deal.
This doesn't even require knowledge of steel and concrete. Simply see that all of the interior box columns, a ring of them surrounded the core all
sheared level. It is elevator guide rail support of landing structures not
core columns. The steel in the center has salvage cuts, not square and level. The image above shows at least a quarter of the core and there is not
one column protruding.
