The “Pancaking” Phenomenon

In the “9/11 debunking the Myths” article, PM refutes many 9/11 conspiracy theories. At the top of the article PM explains that they consult experts to ‘debunk’ the 9/11 myths. One of the myths PM goes after is the “puffs of dust” theory, which basically states that “concrete clouds shooting out a building are not possible from a mere collapse.” PM found the analysis of the collapse in a book entitled Painful Questions: An Analysis of the September 11th Attack. Apparently, the book cites Van Ramero, an explosives expert and VP of the New Mexico Institute of Mining and Technology. PM explains that the expert, Ramero, believes the “puffs of dust” could only have come from explosive devices similar to those designed to take down an “old building”. Well, PM disputes these claims with their own expert, David Biggs, “a structural engineer at Ryan-Biggs Associates and a member of the American Society of Civil Engineers (ASCE) team that worked on the FEMA report.” Biggs explains that the collapsing was basically due to the “pancaking” phenomenon. As the levels of the building began to fall on top of each other they compressed debris and expelled it, which created the “puffs of dust.” My question is who to believe. Both analyses use experts? In debunking any type of myth how do you weigh in on the battle of the experts?
