Just want to remind anyone who is still reading this that we use the experiment of a drop from a height to help out the supporters of this absurd theory, although this was not the case in the WTC where it is estimated by NIST that 85% of the structural columns remained in the floors where the jets impacted.
Please note that jas forgets to mention that many of the remaining columns were damaged by the impact, many others had their fireproofing removed and were severely weakened by fire, and many others were stressed beyond their limit because they were taking the load that had been carried by the damaged and severed columns.
