"...Thus, WTC7 did not collapse due to fire-induced weakening of critical columns"...
"...Temperatures did not exceed 300 °C (570 °F) in the core or perimeter columns in WTC7"...
"...The thermal expansion of the WTC7 floor beams...occurred primarily at temperatures below ~750 °F"...
We are asked to believe that temperatures lower than those seen in self cleaning ovens caused a 47 story building to collapse in a matter of seconds.
A self-cleaning oven is an oven which uses high temperature approximately 500° Celsius (900° Fahrenheit) to burn off leftovers from baking, without the use of any chemical agents.
