NE Corner Assembly, floors 98 to 104, Pops Out, Leads Fall

NE Corner Assembly, floors 98 to 104, Pops Out, Leads Fall


The assembly seems to be severed along a straight horizontal line along it's lower edge, just below the spandrel plate.

It seems to be broken only along bolt connections along it's upper edge.

The piece doesn't seem excessively bent or buckled. The entire corner seems to have popped out without much deformation.

Here the NE corner reveals it's true shape.

A 4-6 story section of 6 N face columns, 12 E face columns and the entire corner assembly.

The bottom of the piece seams severed along a straight edge, just below the spandrel plates.

We can see a large N face perimeter section falling evenly with the NE corner piece, slightly trailing.

There is a large perimeter piece hidden just inside the dust cloud falling from the N (left) face.

The picture bleow shows the falling NE section leads the large north section by a small margin.

The large N face section trails the N face section slightly, but is still obscured by the dust.


The bottom of the NE section has reached floor 78 in the photo above.

The photo below was taken a moment later.


We'll see the bottom of the large section emerge from the dust along the left corner.

The dust has reached floor 87.

More ejections come from floor 78.

The ball of fire marks the 92nd floor.

After a 5 floor fall. The fall starts along floor 97 (98?)

The 97th floor should be meeting the 92nd floor at about this time.

The light grey air ejection from the right floor 87. The light grey dust ejections stay visible in the following photos so we can use them as reference points.


Visual Record of the NE Corner

All photos are in chronological order.

First photo:

Just before collapse.

Red glow is floor 92.

The entire NE corner from floors 98 to 104 will pop out from the building and go into freefall during the earliest moments of downward movement.

A large 6 floor section consisting of the first 6 columns visible on the right, the corner assembly and a 5 story 12 column section from the east side will detach from the building.

This is the E face perimeter layout (just ignore the airplane hole).

I obtained the E face perimeter layout by taking the mirrored image of the N face. You can verify this relation between the N and E faces is correct by comparing it to the 3-D rendering linked below.

Of the 3 possible locations for where the NE corner assembly came from, the blue shape doesn't match the upper break in the columns at the very corner.

We also know from video that everything above floor 97 started to move downwards at the earliest moments of the collapse. The failure line would have gone right throught the middle of the blue shape, yet the falling object doesn't seem to be deformed at all through it's mid-section.

Only the red and the dark green positions match the length of column sections around the corner and wouldn't be ripped in half by the initial failure.

We notice that the entire bottom of the sheet seems severed along a straight line at the botton of a spandrel plate.

We know that the bottom of the red shape is floor 92, too low to have been seriously affected by prolonged exposure to fire and heat.

Therefore the assembly must have been where the dark green shape is marked.

This is the NE corner about 20 minutes before collapse.

The lower edge of the NE corner assembly was severed across the columns along a horizontal line just below a spandrel plate.

The lowest fire is on floor 92.

The green outline had it's lower edge along floor 98. The lower edge of the red outline is along floor 92.

This shows why the green outline is the better choice to locate the NE corner assembly.
