No doubt the plan was elaborate and well executed and required security clearance.
Are you aware that most of the financial sector tenants had their own security systems, procedures, and processes. Even the building security would not have had direct access to those tenant spaces without going through the tenant security officers.
You are asking me to make a stab at how they did this? Surely i can entertain you with the idea, but no one knows how they pulled it off.
If i had to guess, i would imagine about a dozen or so workers were in the buildings as elevator repairmen or maintenance people of some sort.
There were up to 80 elevator mechanics in the building on a daily basis, 24/7. Where they all part of this? No one could access the elevator shafts without them knowing about it.
"
or maintenance people of some sort. " Same objection. There was a large staff of maintenance engineers in the building 24/7. Many of these guys worked there for years and years. They knew everyone that was supposed to be there. They knew everything that was going on.
They probably had those massive metal or plastic wheeled carts that they put their "materials" in to take to the working locations.
In any large highrise building, freight elevator traffic is closely controlled. any major movement of materials and equipment has to be scheduled in advance.
How was this done without causing the other workers to ask questions?
They could have done this at night while there was extremely low elevator traffic.
Night was the busiest time for maintenance work. There were guys all over the building. They knew everyone else. how did they not notice any strangers?
They proceed to access the columns through elevator shafts and other nonintrusive locations.
Well, the elevator shaft idea is simply impossible to support under normal building maintenance processes. Elevators are are subject to "life safety" building codes. any work being done on them is closely regulated and monitored.
Please elaborate on what you consider to be a "nonintrusive location." Since explosive charges have to be placed in specific locations, how does this work?
The devices were specially made to be easy to install and were equipped with high-tech wireless triggers.
Please provide evidence of any explosive demolition process that uses wireless devices.
