This is the image I was trying to post in the original post. Replace the dot and remove the spaces.

ON EDIT:
This is proof that the steel structure that existed inside the core of the twins was not "core columns". FEMA misrepresents what is "elevator guide rail support stetel" as "core columns.
That plate on top of the steel left and right of the center crane is called a "butt plate". It is completely inadequate for joining sections of steel for use as a "core column". Sections of steel that are "core columns" must be 100% deep fillet welded on all 4 faces for a box column. That image shows butt plates in use at the 5th floor.
That steel had no footing foundation. It sat on a "grillage" which is a cribbing stack of steel leveled with a shallow concrete pad.
Butt plates allow the top section to be horizontally shifted and plumbed as the guide rail support steel is extended upwards. The holes can be elongated and the vertical steel shifted over, and it can be shimmed to tilt it.
A butt plate has very little lateral strength, The leverage on the bolts is immense.
Take this point and apply it to the reason that NO STEEL CORE COLUMNS are ever seen on 9-11 in the core area. The elevator guide rail could not stand long enough to be seen after the particulate cleared.
Done deal - we have been lied to.
I can answer nearly all questions on structure and elevator access, core, etc. and back up what I'm saying with evidence of 9-11, ground zero, or construction photos OR, statements of authority totally independent from any governmental or FEMA origin.
In 8 years, no one has ever provided any independently verified evidence to support the notion that steel core columns were in the core of the Twin Towers.
The actual core was totally different, fire would do nothing to it.
