Not that it’ll do any damned good, of course, but keep these images on tap next time you’re accosted by a “Truther.”
One of the “arguements” used by these sad, deluded loons (or outright charlatans) is that the World Trade Center building collapses on 9-11 had to be the result of thermite charges planted inside the buildings in advance, because “fire doesn’t melt steel” and similar rubbish. Well, granted. Burning paper and plastic are unlikely to cause steel to liquify. But consider the photos below of the Hendricks Avenue Baptist Church in Jacksonville, FL. The church went up in flames back in 2007. The Church was a relatively standard steel-frame “warehouse” sort of structure…. almost certainly not filled with napalm, hydrogen, thermite or liquid oxygen. Just the usual wooden pews, tapestries, wood panelling, that sort of thing. See photos of the fire HERE.
The end result of the fire was that the steel structure was left standing, but pretty much everything else was burned away. Take a good look at the aftermath photos, such as HERE and HERE. You know what I see? I see a steel structure, lightly loaded (the beams forming the roof only had to support the roof, obviously, not 20 stories of skyscraper above), and exposed to a relatively brief fire… and sagging under their own weight. No, the steel didn’t melt. But it sure as hell softened. It softened enough that the weight of nothing more than the steel beam caused that steel beam to sag significantly.

Now, imagine what would have happened to this structure had it been fed with jet fuel and had a million pounds of skyscrap on top of it. Does fire need to melt steel for a building to collapse… especially if that building had just been structurally damaged by a jetliner?
Next time you run into a pack of these genetic defectives, mock them mercilessly. If you make them cry, you win extra points (but only if they’re “male,” as making girls cry is dishonorable).
