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:
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.
