there are still questions that remain unanswered, but my main problem is the physics of the collapse and watching that one piece tilt off to the side and then disappear into a cloud of dust. why didn't it topple over to the path of least resistance? does collapsing floors equate to pulverization of concrete and steel into nothing but dust? where were the buildings after they fell? where were the bodies?

The World Trade Center was an engineering marvel and was absolutely designed like all skyscrapers, to collapse on top of itself. This was a topic in my civil engineering college course. The majority of the building was air. Brilliant design.
The essentially hit them in perfect spots. The fuel rich flame was enough to weaken the tensile strength of the steel by 50-60% this the weight above was enough to start the chain reaction of each floor collapsing upon itself. That is a design safety mechanism.
