Fire Melts Steel

In a sane world, this should shutdown the conspiracy nuts ... The NIST investigation into the collapse of WTC Bldg 7 has been completed. It resulted in a series of recommendations for new construction and how to strengthen older buildings for fire resistance.

The fall of the 47-story World Trade Center building 7 (WTC 7) in New York City late in the afternoon of Sept. 11, 2001, was primarily due to fires, the Commerce Department’s National Institute of Standards and Technology (NIST) announced today following an extensive, three-year scientific and technical building and fire safety investigation. This was the first known instance of fire causing the total collapse of a tall building, the agency stated as it released for public comment its WTC investigation report and 13 recommendations for improving building and fire safety.

A cascading collapse of the type that took down Bldg 7 is quite unusual, but the building met the building codes in effect at the time of construction. The improvements are targeted at improving fire resistance overall, and limiting damage of partial building collapse to other parts of the structure.

A summary of the NIST findings is here.

But who is to say the world's population is sane, they keep voting for the fools don't they?
