Then why do ANY buildings require fireproofing of steel structural members?Continuing with Perloff:
"To melt, steel must reach a temperature of about 2800 degrees Fahrenheit. Jet fuel burns at a maximum of 1500 degrees, and most experts concur that the World Trade Center flames probably didn't exceed 500-600 degrees. Exposure to such flames wouldn't melt the buildings' steel any more than your stove's gas flames will melt your pots and pans.
What would cause steel to melt would be detonation of the military explosive thermite, which reaches 4500 degrees in seconds.
It would also explain why the building's concrete pulverized into dust instead of falling in large chunks.
With over 1,700 building professionals in its ranks, Architects & Engineers for 9/11 Truth (www.ae911truth.org) has documented overwhelming evidence that the Twin Towers' collapse resulted from controlled demolition..."
(taken from pages 175 and 176 of James Perloff's book.
And how does one account for the same kind of collapse for Building Seven for which no one claims a plane touched?
All three buildings tumbled down neatly into their own footprints.
Surely the threat of Thermite at the local mall or theater or Walmart is astronomically small.
Could it perhaps be that Steel looses a percentage of its structural strength at temperatures far lower than its melting point?
(I find it incredible - literally not credible - that 1700 Architects and Engineers do not know this basic fact necessary to pass the licensing exam.)
I have not examined any evidence for Building Seven, so I have no idea why it collapsed. Some possibilities include wind load or seismic forces from the collapse of adjacent buildings, flawed structural design or construction, debris impact, collapse of underground tunnels or some combination of factors.
