Why the World Trade Center Buildings Were Being Brought Down by Airplanes

Some have proposed that the building may have contained something incriminating, like records or equipment that needed to be destroyed. But even if i wanted to bring down the whole building, this is not remotely how i would do it. It's much easier to explain the collapse of the structure if you simply fly a plane into it. So i don't think the control demolition scenario makes sense here. Whatwould odo instead? If i'm trying to sell the public on the idea that the world trade center buildings were being brought down due to airplanes hitting them, I would do the obvious thing and have an airplane slam into world trade center seven as well.
