Architects and Engineers for 9/11 Truth

Also, the buildings didn't drop similar to how buildings implode (how many truthers claim it happened) because there were no successive explosions on various levels. It came down from the very top first, and fell on top of itself stressing out the beams and bringing the rest of the building down. Debris was scattered for miles. An implosion explosion similar to how the conspiracy states would have a more controlled explosion.

Hope that clears things up.

I found a paper written by a guy with a B.S. in physics that says that can't happen.

The melting point of steel is only 2500 degrees (no steel is rated that high. Pure iron has a melting point of 2750, steel is an iron alloy and any mixture will have a lower melt point). However it becomes soft and malleable at just over 2000 degrees, NOT 3000. So if the fires were burning and warping steel, how could something softened to that degree hold up a building anymore? It doesn't. It falls.

The fundamental problem with the jet-fuel-melting-steel explanation is that its premise contradicts the laws of physics. No amount of ‘ “aviation fluid” ’ burning in the open flames of a building fire could even begin to melt steel. 1535ºCelsius/2750F is the melting point of structural steel, whereas 825ºCelsius/1517F is around the maximum temperature attainable with hydrocarbon-fueled fires without systematic pre-heating or pressurization of the air.

And I could find a physicist that says the opposite. The reason everyone rushes to the melting point is to augment the reality of the situation. Steel does NOT have to melt to lose it's integrity. A plane crashing into a building, and impacting the structure could trap pockets of burning fuel, pressurizing and allowing for the super heating needed. Steel doesn't need to melt to make what happened, happen. There didn't need to be a giant vat of molten steel pouring out of the windows to be the ONLY way it could have fallen.

Here's an experiment. Make a large spindle of solder into a column and balance a large board on top of it. Then take a butane lighter and place it close (not on) the spindle. What will happen is the solder pillar will fail before it actually melts. That's the same concept, with with stronger steel and a much hotter flame, and TONS more weight.
