Thats a valid assumption.

I am not sure of Turner Const. Co. myself, and there can be more than one group involved so I wouldn't rule out anyone just yet, TCC just have the skills background, the building access to WTC, and links to military demolitions material that makes them my prime suspects. Add to that, I suspect its CEO at the time was a Zionist too having received an award from the AJC. In the King Dome demolition, TCC acted more like a project management consultant and contracted out the actual demolition work to another company. The WTC, being bigger probably needed even more skilled study and rigging than the King Dome did.

The Mossad was caught filming and celebrating the event and has links to Silverstein through the Israeli government, so that makes them a suspect as well (they could have been filming their own or their colleagues operation and remember the just in time transfer out of Israeli WTC tenants).

Suspects can be cross referenced for their presence at the Oklahoma City bombing which looked like a first test for a false flag high rise building demolition. I believe Controlled Demolitions Inc. was a clean up contractor for that site as well as WTC, so I would add them to the suspect list.
