This slide show helped me understand the floor system and the concrete reinforcing wire.

Thanks. This helps in gaining a better conceptual understanding

Thanks. The slide show helps...incredible forces were needed to pulverize the floors and contents.
The idea that a plane brought a Tower down looks pretty ridiculous when a person views slides of the buildings being constructed.
