Intense Heat Persisted for Months
- Fires continued to burn deep in the rubble pile for 100 days,
despite the spraying of water onto the pile.
- When the rubble was cleared, pools of previously melted steel
were discovered at the foundations.
- Temperatures needed to melt steel (1535º+ C)
could not have been caused by residual hydrocarbon fires.
A blast furnace is normally required to melt large pieces of steel.
