Why the World Trade Center towers fell
Purdue University and the American Society of Civil Engineers collaborated on an elaborate computer simulation of the planes striking the WTC twin towers. In a video from National Geographic TV, they present their conclusion that heat from the combustion of the fuel weakened the supporting structures sufficiently and broadly enough to allow both buildings to collapse into their footprints.
This addresses the MIHOP conspiracy theories, though not the LIHOP ones.
