The Anatomy of a Great Deception Quote
Frank DiMartini (WTC Construction Manager): The building was designed to have a fully loaded 707 crash into it. That was the largest plane at the time. The building probably could sustain multiple impacts of jet liners because this structure is like the mosquito netting on your screen door. The jet plane is just a pencil puncturing that screen netting.
