in fact the trusses extended from 5th to 7th floor, the 6th floor slab had a big openings in it, so it's difficult to find the difference between 5th and 6th floor, either way the 5th and 6th floor were mechanical floors, they used thermite on that floors, if there was a partial collapse, then the fire could escape to the 7th floor (if you understand me), nevertheless there was second "row" of charges on the 13th floor, the truss number 3 (west side of the building) was attacked on that floor (respectively core columns 61+/62,63), the collapse was initiated by column 80 or 81 (not 79 as NIST claims), 80 and 81 were accesible from an acess ramp on the 5th floor, unlike 79 It almost looks like I'm one of the preparators......... |
