Now, the heat caused column failure, but the building then fell upon itself. So the entire building itself as well as the ground and the fuel (not necessarily jet fuel) created a huge insulated fire. I'd guess (I am not perfectly certain) that because of those conditions, the fire could get hot enough to melt steel.
How could that be? Paper, chemicals, office materials, and other things burning underground? Buried beneath an entire buildings worth of concrete and dust..
What are the three essentials for fire? Seems one of them should have been in short supply.. Remember, we are talking 6 weeks after 9/11...
