WTC1 88th fl S face light grey ejection

WTC1 88th fl S face light grey ejection

From this video clip. The same clip is embedded below.



The following gif contains the 2 images above. There is an interval of 10 frames between each image (at 30 frames per second):

The frames are

f755 south side ejection from around floor 87 already visible
f775 ejections appear around NW corner (green line) and along north and west faces of floor 98

at 1/3rd second interval between images.

Achimspok locates the ejection from the west view:

and concludes correctly;

The same ejections as seen from south:

Achimspok locates the ejections from the south view:

Therefore ejections extending as low as the 87th floor on the south face are visible before ejections appear along the north and west faces along the 98th floor.

Frames from Achimspok analysis taken from this clip. The same clip is embedded below.


The purpose of the red arrows is to point to common events in order to synchronize the north view and south view videos.

Once synchronized, we can see that the strong light colored ejections from the middle of the south face emerge as low as the 87th floor and are visible when the antenna has tilted less than 1 degree and the NW corner is just beginning to fail.

In the gif above, we can see that the NW corner has barely begun to fail when the south side ejections are visible. We see forceful ejections with what appears to be concrete dust as low as the 85th floor, as the video linked below shows.

We also see a large ejection of fire out of the SE corner well below fl 92, which is the lowest floor in which fire was visible.

Good clips

Another clip that captures the 88th floor south face ejections:

This next clip shows the same south side ejections synchronized to a video of the collapse from the north to demonstrate the evolution of movement from the north at the time the ejection is witnessed:

The dust emerges when the northwest corner has only fallen a few feet.

The tilt angle varies from 0 to 2 degrees over this interval, meaning the south wall has fallen only about 12 feet by this time in the region of floor 98. The ejections emerge from areound the 89th floor. They are light grey, not darker colored like the smoke and ejections above.

They begin to emerge at the time shown in the gif leading off this section.

Note that this type of free-fall perimeter sheets has no similarity to the WTC2 east wall. It is similar to the WTC1 west wall where the sheet just above the failure line falls out and over the lower sheet.

Remember, if inward bowing led to the style of failure that the WTC2 east face experienced, there would be nothing in freefall as seen. The inward bowing would pull the upper sheet behind the lower sheet and the lower sheet would be pushed outward.

This evidence shows that this couldn't have happened to WTC1 south face. Upper did not tuck behind lower. Upper broke outward and over lower, just like the WTC1 west face and north face.
