This is a 'peer-reviewed' scientific paper. This cannot be ignored or discredited unless the research is later 'proven' to be incorrect. Simply denying it's content and implications is meaningless.

All three steel structure buildings that collapsed in NYC on 9/11 did so in near freefall acceleration. Never before or since 9/11 have steel structure buildings completely collapsed due to fire. Collapsing downward symmetrically 'into the path of most resistance'. Multi-ton steel support columns were laterally ejected outward as far as 600 feet from their point of origin. If the official government conspiracy theory claims that these buildings all fell as a result of a gravity driven collapse then where did the energy come from the ejected these large steel columns outward? What was the energy source that caused all of the concrete in the two towers to be pulverized into a fine power. How did these buildings collapse at essentially the same speed as it would take to drop a ball from the top of these buildings to hit the ground with only air as it's resistant force?

Although NIST was required by fire codes to test the dust and debris for sign of explosives they did not test for those.

WTC Building #7 (a 47-story high-rise not  hit by an airplane) exhibits all the characteristics of a classic controlled demolition with explosives:  (and some non-standard characteristics)1.  Rapid onset of “collapse”2.&nb sp; Sounds of explosions at ground floor - a full second prior to collapse3.  Symmetrical “collapse” – through the path of greatest resistance – at free-fall speed4. Imploded, collapsing completely, and landed mostly in its own footprint5. Massive volume of expanding pyroclastic dust clouds6. Several tons of molten metal reported by numerous highly-qualified witnesses7.  Chemical signature of Thermite (high tech incendiary) found in solidified molten metal, and dust samples by physics professor Steven Jones, PhD.8.  FEMA finds rapid oxidation and intergranular melting on structural steel samples9. Expert corroboration from the top European Controlled Demolition professional10. Fore-knowledge of “collapse” by media, NYPD, FDNY

Bill Manning, Editor of Fire Engineering Magazine, referred to the 9/11 investigation as a 'half-baked farce' and also pleaded for the removal of the steel from GroundZero to stop being sent off to China without allowing for a full investigation.
