  • "These professionals who collectively have over 25,000 years of experience have signed our petition calling for a new investigation."
  • "A localized failure in a steel-framed building cannot cause a catastrophic collapse like a house of cards at free-fall acceleration."
  • "All three collapses were very uniform in nature. Natural collapses due to unplanned events are not uniform."
  • “Building 7 came down very smoothly. NIST tried to prove the ridiculous theory that this was started by one column.”
  • “After much studying, it is obvious that NIST has fallen short of a detailed accounting of the collapses of the three WTC buildings.”
  • “In an office fire, you cannot generate enough heat to melt steel. And yet we have evidence of molten iron in the rubble pile.”
  • “I have known from day one that the buildings were imploded and could not have collapsed from the damage caused by the airplanes.”
  • "The official explanation of the failures defies known scientific methods of analysis and is untenable in the face of logical investigation."
  • “There is little doubt that the collapses were caused by controlled demolitions and the aircraft impacts were causal ruses.”
