A new study using 3-D simulation is giving engineers more information about the collapse of the World Trade Center towers.

The simulation from Purdue University shows that when the planes struck the buildings, they stripped away crucial fire-proofing material. The aircraft's fuel then ignited and produced a flood of flaming liquid that knocked out columns within the building.

The weakened towers then collapsed under their own weight.

Researchers on the study say the work shows the absolute need to fireproof steel structures. When the World Trade Center was built, codes did not require steel beams to be fireproofed.
