-Protec employee Brent Blanchard-
Jim Hoffman replies to Blanchard’s paper “A CRITICAL ANALYSIS OF THE COLLAPSE OF WTC TOWERS 1, 2 & 7 FROM AN EXPLOSIVES AND CONVENTIONAL DEMOLITION INDUSTRY VIEWPOINT”
Blanchard constantly claims that parts of explosives such as det cord should have been found in the debris. However, a phone conversation with Dr. Steven Jones suggests otherwise.

-Physical chemist Dr. Frank Greening-
Dr. Greening makes a lazy attempt at refuting the Active Thermitic Material paper. Dr. Steven Jones responds.
Dr. Greening hypothesizes that there could have been natural thermite reactions within the WTC buildings. Mechanical engineer Gordon Ross addresses these claims.

Pat Curley: the king of scientific peer-review.
Pat Curley attempts to cast doubt on the results of the Active Thermitic Material paper. John-Michael Talboo demonstrates why he is wrong.
Pat Curley claims that Steven Jones makes a strawman argument, but only exposes his own failed logic and poor research.
James B. claims that “trutherism is a mythology, not a science.” I show why he is completely wrong.
