Why Indeed Did the World Trade Center Buildings Completely Collapse.pdf

Reasons to Challenge Government-sponsored Reports
  1. Molten Metal: For six months after Sept. 11, the ground temperature varied between 600 degrees Fahrenheit and 1,500 degrees, sometimes higher. The temperature of the fire at the WTC was not unusual, and it was most definitely not capable of melting steel.
  2. Observed Temperatures around 1000°C and Sulfidation in WTC 7 Steel: Rapid deterioration of the steel was a result of heating with oxidation in combination with intergranular melting due to the presence of sulfur.
  3. Near-Symmetrical Collapse of WTC 7: Even though fires were randomly scattered in the building.
  4. No Previous Skyscraper Complete Collapse Due to Fires: Experts said no building like it [WTC7], a modern, steel-reinforced high-rise, had ever collapsed because of an uncontrolled fire.
  5. Plume-timing during the Collapse of WTC 7: Horizontal puffs or plumes of smoke and debris are observed emerging from WTC-7 on upper floors, in regular sequence, just as the building starts to collapse. The timing between the puffs is less than 0.2 seconds so air-expulsion due to collapsing floors is excluded.
  6. Early Drop of North Tower Antenna: What caused the 47 enormous steel core columns of this building which supported the antenna to evidently give way nearly simultaneously, if not cutter charges?
  7. Eyewitness Accounts of Flashes and Loud Explosions
  8. Ejection of Steel Beams and Debris-plumes from the Towers: The horizontal ejection of structural steel members for hundreds of feet and the pulverization of concrete to flour-like powder, observed clearly in the collapses of the WTC towers, provide further evidence for the use of explosives.
  9. Rapid Collapses and Conservation of Momentum and Energy: The rapid fall of the Towers and WTC7 has been analyzed by several engineers/scientists. WTC 7 falls to earth in (6.5 +- 0.2) seconds, while an object dropped from the roof (in a vacuum) would hit the ground in 6.0 seconds.
  10. Controlled Demolition “Implosions” Require Skill: A true implosion, demolishing the building so that it collapses straight down into its own footprint requires such skill that only a handful of demolition companies in the world will attempt it. Why would terrorists undertake straight-down collapses of WTC7 and the Towers, when “toppling-over” falls would require much less work and would do much more damage?
