In the southwest there are some Wal-Marts that, despite steel columns, have overall roof framing of structural lumber and wood truss-joists. This can only be done in low snow load areas for structural reasons.

I guess I should offer that roof framing wouldn't be a big culprit. Any building can burn quite nicely, due to contents, no matter how fire resistive the framing.

A major conflagration would be more a factor of an automatic fire sprinkler system malfunction than anything else.

Even with modest contents burning, the air gets so hot inside a fire area that floor coverings, paint and items that have low-flame spread ratings still end up contributing to the fire. Eventually the normal non-combustable items loose their structural strength -- voila, World Trade Center.

Yup. If you want to take out a building, first sabotage the sprinkler system

BTW, remember the TN driver license scandal? One of the møøslimbs that Kathrine Smith gave multiple licenses to (before she was burned alive in her car) was carrying a contractor's work permit to fix the sprinklers at the WTC.

The WTC didn't contract out sprinkler work...

The pass gave him access to the buildings' sprinkler systems.

I bet he "fixed" them real good...

Treason is not too strong a word.
