To compare a bridge overpass collapse to the collapse of a steel structure high rise building is absurd. A bridge overpass is not a redundant structure and therefore does not have the same type of reinforcement structure. The debunkers point is meaningless.

And they have failed.

What I've learned from studying it, is that the media will always report that stuff 'melted' without any substantiation! There are numerous examples, but I don't have the time to go into it at length here.

Trust me, unless fire theory needs to be revised, temperatures of hydrocarbon fires do not exceed 1000-1200 centigrade.

Structural steel has a melting point around 1500 degrees centigrade.

There are a number of things to consider:
* Alloy of the steel
* Fire proofing
* Duration of the fire
* Gas temperature as opposed to steel temperature (Did the steel reach the same temperature as the fuel/oxygen mix?)
* Loss of structural strength before melting
* SPOF (Single Point Of Failure)

In fact, 9/11 "debunking" is itself a quasi-Byzantine complexity full of snares and delusions and peopled with false friends, lunatics, earnest lost souls and NO heroes.

By contrast, my experience with serious 9/11 Truthers has shown me: MANY heroes.

There have been many kinds of people, professionals, technical, perceptive, and yes some oddballs too, but far and away most have been intelligent and courageous. Partly I suppose because those qualities, especially early on, were helpful in seeing through the farce.
