“What about the countervailing reasoning? The supposed “controlled” demolitions had to be initiated at each tower’s damaged zone. Each was a site of major fire, and had been subjected to something resembling a fuel-air bomb when the aircraft struck (massive fireballs recorded on video). How were these critically important demolition materials, including explosives, supposed to withstand around 45 minutes and 90 minutes of intensive fire? It’s absurd.”
The spectacular fireballs lasted a few seconds and burned most of the fuel. Great visual effect but little fire damage. The resulting office fires affected relatively small areas of the towers.
