I will have accountability and you will have none.
They are called the "Twin Towers", naturally we think they are the same.
The images showing people entering elevators from the lobby was counter to what I knew about WTC1. The documentary was primarily about WTC1. However, near the end of the second half there was some information about WTC2.
That information went back to the original complaints about WTC1 and the fact that entry into the core was required at all levels to get an elevator. This was most objectionable to designers at the ground lobby level.
The second part of the documentary actually showed an image, perhaps video of a rocket launch pad at cape canaveral which was built to test a structural configuration which allowed rocket exhaust ports all the way around the launch pad but still had adequate strength at the periphery edge to support the gantry.
That test and configuration had a dual application. The ports allowing rocket exhaust to escape became elevator entries in the WTC2 tower, core base.
That latter part of the second segment also provided details on the altered core design based on cell/shear design parameters.
WTC1 had strict shearwall design in its construction as ideally, albeit simply conceived by Yamasaki. In addition to no elevator entry at ground lobby level direct int elevators, it only had one hallway per floor in perpendicularly directions, alternating with each floor upwards; in order to eliminate the hallway openings, one over another; interrupting the shear walls of the bottom 43 floors.
The heavy elevator equipment was housed below the 43rd floor skylobby and above that, at some point, hallways went both directions at each floor.
WTC2 had a completely redesigned structural basis. It was combined cell construction with each cell having its own shear capacity. There was a third wall across the narrow axis of the core.'
That third wall only had openings in it for the emergency stairs to ramp back and forth inside the core. The third wall, comprising a wall of the small cells each having their own shear, made it possible to have a hallway on each end of the core crossing the narrow axis. There were also two that were narrower running the long axis halfway to the third wall.
The third wall at the center of the long axis crossing the barrow axis is why the WTC2 core in this photo shows a rounded top. That higher portion is created by the third wall.
The core of WTC2 was oriented with its long axis north and south. The photo is taken from the west looking east.
I have been accountable to this many times, but not once have you or any other explained how hallways and elevator openings existed within the maze of diagonal braces needed for a steel framed core with columns.
No one has ever produced an image from 9/11, showing such structure. All they ever produce is construction photos that they misrepresent and which still never show diagonal bracing in the core.
The construction photos show elevator guide rail support steel necessarily inside the core but NOT structural
elements of the core. This is why the core in 9/11 images is always empty. All elevator equipment and guide rails fell as soon as the core was demolished.
