yeah, construction techniques in 2009 vs 1968Why didn't you post an image of steel core columns?
Those concrete cores were constructed differently than the Twins. The Twins were made like WTC 7's new core. After the steel was in place.
STRUCTUREmag: Concrete Construction at 7 World Trade Center
Having chosen the system, Tishman Construction compared the pros and cons of constructing either the concrete core or structural steel first. An additional factor to be considered, as noted by Allan Paull, was the fact that the labor union in New York City does not allow concrete construction to be performed above steel workers. The steel-first approach was chosen based on the following advantages: expedited construction of the mechanical/electrical work, simplified building hoist, simplified crane logistics, expedited curtain wall construction, and a reduced overall construction schedule and cost.
hey dipshit, THAT Shows STEEL CORE COLUMNS ON 9/11The steel is toppling from the north core wall or the west, NOT THE CORE.

If the camera were turned to the right it would see an empty core like is seen here.

The concrete core is not a theory. It is fact. The information I have on it is not perfect.
a fact?
keeping clicking your heels together with your eyes closed and repeating "there really is a concrete core. there really is a concrete core. there really is a concrete core." and it might eventually come true.

stans columns are shown to be either outside the core or the first elevator support steel.
