I've been a bit preoccupied with our holiday guests and the phantom toilet clogger (no one will fess up...) to do much reading. I will say that every conspiracy theorist I have spoken to, when confounded with facts disputing their position, returns to the original question, "What temperature does steel melt at and what temperature was the fire at it's hottest?"
They are further confounded when I declare that is not the salient question. With the forces applied to that steel, how hot must it be to lose it's integrity? Steel loses it's ability to support tons of weight to the point of collapse at a much lower temperature than what it takes to melt it. In fact anyone who has ever worked with steel knows that one can weaken it with natural flame to the point that a man can distort it's shape with his own strength.
Ultimately, my experience with 911 conspiracy theorists is that they are more convinced by their own political agenda which is then projected onto the theory. They rely on half truths, distortions, ignorance and laziness to promote their perspective. No doubt they are seductive....if we ignore what we actually saw and believe a political conspiracy like this can actually be suppressed by the hundreds of bureaucrats that would have to be involved; the truth never to emerge from within.
