Photo archive of debris in the area east of WTC 2 here
1) The spandrels along the blue lines pull inward and downward. The
upper large standard sheet is pulled behind the red sheet, breaking
along the upper edge of the large MER stiffening plate (green belt).
The upper edge is marked in purple.
2) The red middle sheet falls outward, breaking at the base just above
the 41-43 MER panels and fall down over 40 fls to earth leaving the
purple lower sheet standing. It also breaks along the upper edge of the
41-43 MER stiffenig belt (purple line).
3) The lower sheet then falls outward and was found lying practically
interconnected from the base of the footprint to the 44th fl.
4) The stiff NE corner breaks along the 3 red marks. No info on SE corner breaks.
5) The top of the tower pinched inward just under the hat truss and top MER stiffener as it was leaning (as shown).
UPPER SECTION
The upper sheet falls completely behind the middle sheet:
There is evidence that the east facade of WTC 2 from the 80th floor
downwards fell as an interconnected single sheet of unbuckled perimeter
column sections. The spandrel plate connections and column-to-column
bolt connections remained largely intact until far into its fall.
Here is a glimpse of the sheet falling away from the building:
which fits the pattern of the lowest bolted connections shown above with the addition of 2 more panels shown in red:
Note the middle sheet falling away from the building. the upper MER level (fl 43) is morked in red.
The middle3 sheet will emerge from the building dust moments later as seen in the video below.
The middle perimeter from fls 78 to 44 is seen emerging from the bottom of the bulging dust in this video:
Wide MER spandrels for fls 41-43 north half marked in red. Wide MER spanrels for south half marked in green.
This is the debris as it looked just after 9-11-01. The large MER
sections sit at the very end of what appears to be a large, rolled-out
sheet of perimeter wall. It is, in fact, the entire east side of WTC2
from the 41-43 fl MER level downward., about 60 columns wide (57 to be
exact, excluding the cornermost sections).
A view from the side. The MER panels marked in green are along the bottom of the photograph.
Blue lines mark the wide spandrels from the lowest MER level above
ground level. The red and blue boxes mark where the right and left
halves of the 41-43 MER perimeter were found.
Other wide MER spandrels are marked.
Clean-up operations have already cleared debris in the lower left corner
of the photo but the size of the intact east side of the building is
obvious.
Even from the debris we can see that the spandrels split along the NE
and SE corners of the building yet remained relatively intact between
the corners.
Note the identical break line relative to the wide MER spandrels that was seen above the 75-77 MER failure line.
There is only one unique place it can fit in the graphic: It is the
entire right half of the perimeter wall. The broken spandrels on the
right must be one perimeter panel (3 columns) in from the northeast
corner of the building.
The piece next to a street sign:
And where is the intersection of Church and Cortlandt? In the red oval below.
We can see the entire east face of WTC2 below floor 81 "peeled" away
from the building, falling over WTC4, its top edge (the mechanical room
sheets) landing along Church Street.
