In reply to the discussion: Cutter Charges in the North Tower... [View all]gyroscope
(1,443 posts)3. NIST explains them as pressurized puffs of air
that are ejected horizontally by the the pressure of the collapsing floors.
first of all, these are not puffs of air. they are pulverized building materials.
there's a whole lot of solids in them.
second of all, if they were highly pressurized puffs of air they would be blowing out of ALL the windows of the floor not just exiting out of a single window. unless NIST is claiming each floor had only one window? hah!
welp, there goes another official theory out the window.
