WTC2 75th Fl Beam Flooring Ejected still attached to MER peremeter

The permeter sections marked in red, blue and green separate from the building and fall along the paths marked.

The red and blue sections had beam flooring still attached and were ejected with considerable outward force. The green corner MER panel fell down the NW corner while spinning as a result of impulse delivered to it during destrution of the NW MER corner.

The destruction and reconstruction of the MER perimeter is identifiable in these video clips:

Using the highest resolution image, an intact floor slab is seen still connected to the SW corner (blue) MER perimeter.



This is the south quarter of the perimeter, 18 column or 6 panels wide. Note how the 6 cornermost columns are bnet backward out of view.

This is the beam layout of 75th floor beam flooring:



As the beam layout shows, the corner beams are short north-south beams, the long span beams beginning about 15 ft inwards from the corner. The bend in the sheet corresponds to the tramsition between short beam and long beam flooring.


The NW and SW corner MER sections are used to reconstruct the whole west MER perimeter wall here
