Post an image of the supposed steel core columns in the core area showing their interconnections from 9-11.
Here is what I know is a rectangular concrete tube.
On September 13, 2001 the engineer of record provided information to Newsweek identifying a concrete core.
In 1990 I viewed a 2 hour documentary about the construction of WTC 1 titled, "The Engineering and Construction of the Twin Towers" and most of it was about a concrete core.
Oxford Illustrated Encyclopedia of Invention and Technology, of 1992 identifies a concrete core.
your text is meaningless. this has all been debunked already. there is no concrete in your picture.
null post.
