The following sequence of images show the initial ejections emerging from the east face during collapse initiation.
There images were taken from a video clip in which the camera was stationary
Each colored line represents one floor height. The colored lines remain stationary so you can see how ejections emerge and whether they skip floors.
In the photo sequence above I would judge the 81st floor to be along the top yellow line, possibly the green.
Notice the first row of ejections occur along the white line.
Rows of ejections seem to skip floors.
In this and the next presentation I'd like to prove the following claim:
The lower east perimeter sheet was broken from the top part along the bolt connections shown along the red line in the image below.
The entire east wall peeled away from the building as a single sheet below this line, the edges of the sheet being exactly where the red line indicates.
Could these rows of ejections correspond the broken bolt connections?
The following photo shows the original fire and damage along the east face relative to the mechanical room.
I show the boundaries of the peeled sheet below over an inverted image taken from a NIST report. If the creative and patient reader can just ignore the airplane hole, the column layout is exactly as that of the east face around floor 80 (except for the centermost 3 column prefab section).
The top of the sheet was caught on many videos and it has the same shape and comes flrom the same location as the marked sheet. I will show this in the next presentation. For now let the following two images suffice to show every part of the entire east perimeter, from just above the mechanical room floor downwards, was placed in a remarkably organized and recognizable form: As a single sheet laid outwards.
Please look closely at the object below. This is exactly one-half of the perimeter wall across the mechanical room, it's bottom stuck into the earth.
You can see both halves placed next to each other in the image below.
This is from before clean-up operations. You can clearly see where the debris (perimeter columns) ends.
They are just where we would expect to find them: At the top end of the sheet. The very top of the large lower west sheet
is the top of these pieces and would contain quite valuable evidence of device or explosive residue if any were used.
The tops of these columns, within 2 floors of the east wall collapse initiation we witnessed, appear totally unbuckled.
The top of the peeling sheet is shown and these columns identified in the next presentation.
The entire east perimeter is laid out so cleanly in the photo below that I bet if you counted how many columns wide the sheet is, you would count exactly 57. They are split right along the last column of the sheet and the corner column on both sides, always along bolt connections.
This photo is a cropping of a satellite image showing how the sheet is seen from above. The top of the sheet is at the bottom of the photo. This photo was taken a bit into clean-up yet clearly shows the entire wall fell as a single unit.
The short video clip linked
here shows the top of the sheet as it peels away from the building between 0:17 and 0:19.
All elements presented here are visible in the clip. Note the two rows of forceful ejections followed by the emergence of the large sheet, falling not downwards but
outwards.
The top edge of this sheet is broken only along bolt lines, appears totally unbuckled and is the exact same shape I outlined a few images ago.
I will confirm this claim the next presentation.
