In two new video clips by femr we can see the moments when the upper perimeter sheet separates and falls from the lower sheet along the WTC1 northwest corner and the first 12 columns on the north face without a trace of buckling
Because of the wind direction these columns are more visible than the others which are obscured by a veil of smoke.
The first clip is a close-up of these columns. Same link as in the last post, relinked below
1) Early outward forceful movement of a column about 10 spaces from the corner. The column is clearly pushed outwards with significant force even before the corner fails.
2) Not the slightest trace of buckling, ripping or any kind of deformation due to resistance to failure during the sheet separation.

In the second clip we see the same columns from a wider perspective. We see a small section of perimeter columns remain standing. It is easy to verify the top of this piece is from the 97th floor along the collapse initiation failure line and the columns are the first 6 from the NW corner on the west side of the building. You can see where it comes from via the clip itself.
Please consider these simple questions concerning this rather frail, narrow surviving group while watching:
1) How can the bolt failures along it's edges all break so delicately so as to leave such a frail piece remain suspended in air
If these bolts were actually ripped by force, why didn't it at least pull the piece down with it?
Consider how much force is required to rip bolt connections relative to how little force is required to knock this frail piece over.
Dearest reader, just reflect a bit and you will come to realize that what you are seeing is physically impossible.
The bolt connections on both sides must, must
have been pre-cut or weakened for this unstable piece to be ripped away from the falling structure and still stand.
2) Why is there no trace of buckling or ripping seen on the top of this surviving piece since it's top was supposedly firmly attached to the upper block moments ago?

The HD version is good.
