DID THIS BUILDING COLLAPSE BY FIRE?
If so, then Salomon Brothers (WTC 7) building sudden collapse should have changed everything for High Rise Fire Operations, Safety and Construction.
3:50 PM scattered office fires in the Salomon Brothers building.
5:20 PM - no major fire visible in Salomon, yet first ever sudden and complete collapse of a Type 1
fire-resistive building from fire.
5:20 PM collapsed in under 7 seconds into its own footprint. NIST claims that ordinary office fires were responsible.
WHEN NONE OF THESE DID?
