The building was designed to have a fully loaded 707 crash into it, that was the largest plane at the time, i believe that the building probably could sustain multiple impacts of jetliners, because, this structure is like the mosquito netting on your screen door, this intense grid, and the jet plane is just a pencil puncturing that screen netting, it really does nothing to the screen netting.
