Sounds logical to me

I wish the 9/11 Commission would explore this line of reasoning…

Given that:

A)  The WTC towers fell straight down;
B)  For a building to fall straight down, its steel supports must be destroyed symmetrically (http://science.howstuffworks.com/building-implosion1.htm);
C)  The temperature needed to melt steel is much higher than the temperature needed for a person to survive;
D)  Some people survived from above the point of impact, escaping down an intact stairwell (http://www.usatoday.com/news/sept11/2002-09-02-choices-usat_x.htm);

…then the heat applied to the steel supports could not have been symmetric, therefore, the WTC towers were not brought down by burning jet fuel.
