I copied the material below from AE911Truth.org. It’s from their older site. The material is worth preserving.
WTC Building #7, a 47-story high-rise not hit by an airplane, exhibited all the characteristics of classic controlled demolition with explosives:
- Rapid onset of collapse
- Sounds of explosions
- Symmetrical structural failure
- Free-fall acceleration through the path of what was greatest resistance
- Imploded, collapsing completely, landing almost in its own footprint
- Massive volume of expanding pyroclastic-like clouds
- Expert corroboration from the top European controlled demolition professional
- Foreknowledge of “collapse” by media, NYPD, FDNY
In the aftermath of WTC7’s destruction, strong evidence of demolition using incendiary devices was discovered:
- FEMA finds rapid oxidation and intergranular melting on structural steel samples
- Several tons of molten metal reported by numerous highly qualified witnesses
- Chemical signature of the incendiary thermite found in solidified molten metal, and dust samples
WTC7 exhibited none of the characteristics of destruction by fire:
- Slow onset with large visible deformations
- Asymmetrical collapse which follows the path of least resistance (laws of conservation of momentum would cause a falling, to the side most damaged by the fires)
- Evidence of fire temperatures capable of softening steel
- High-rise buildings with much larger, hotter, and longer lasting fires have never collapsed
As seen in this revealing photo, the Twin Towers’ destruction exhibited all of the characteristics of destruction by explosives:
- Destruction proceeds through the path of greatest resistance at nearly free-fall acceleration
- Improbable symmetry of debris distribution
- Extremely rapid onset of destruction
- Over 100 first responders reported explosions and flashes
- Multi-ton steel sections ejected laterally
- Mid-air pulverization of 90,000 tons of concrete & metal decking
- Massive volume of expanding pyroclastic-like clouds
- 1200-foot-diameter debris field: no “pancaked” floors found
- Isolated explosive ejections 20–40 stories below demolition front
- Total building destruction: dismemberment of steel frame
- Several tons of molten metal found under all 3 high-rises
- Evidence of thermite incendiaries found by FEMA in steel samples
- Evidence of explosives found in dust samples
The three high-rises exhibited none of the characteristics of destruction by fire:
- Slow onset with large visible deformations
- Asymmetrical collapse which follows the path of least resistance (laws of conservation of momentum would cause a falling, intact, from the point of plane impact, to the side most damaged by the fires)
- Evidence of fire temperatures capable of softening steel
- High-rise buildings with much larger, hotter, and longer-lasting fires have never collapsed
