A study out of Perdue University again shows how the loss of fire retardant from the pressure of the plane, the destruction of many of the inner pillers from the titanium Airplane engines and fusilage, and the weakening of steel due to the fires was the cause of the collapse of the World Trade Center buildings. The study will help engineers to better design tall buildings, and included computer simulation to assist in the technical analsysi.

In the animation, elements that were not part of the scientific simulation, such as flames and smoke, are clearly rendered, although the visualization does not show the subsequent effects of the fire.
Of course, this won’t convince conspiracy theorists any more than a similar analysis done by Popular Mechanics. If you debunk one fact, they will either ignore it, call you simply come up with another fact or another expert (who often is a professor from a different specialty of science, or not a scientist at all). Indeed, they often recycle debunked “facts” again, figuring the attention span of the public won’t notice. The blog ScrewLooseChange has lots and lots of information on the debunking and recycling of “truth”.
Those who take one fuzzy idea out of context, mix with hatred of President Bush/the government, and spout off are examples.
