Introduction to, the painless quick death and proper burial of piston theory:
Curioso number 6: Ejections below the "collapse" front.
Unquestionably the most interesting place to study these ejections is during the "collapse" of the North Tower, northwest corner.
Within all the South Tower video clips I only see 3, maybe 4 ejections well below the "collapse" plane: The 2 previously shown on the south face, 1 on the east face, center of the building around floor 40 to 45 and maybe one on the northeast corner, midway up the building.
On the North Tower, northwest corner we have 3 pairs of forceful ejections clearly visible. There are recurring mathematical patterns seen in each of these pairs of ejections. They duplicate themselves.
The first two pairs first appear with a forceful ejection on the west face quickly followed by another ejection on the north face one floor below. The third pair is identical but reversed: The first ejection is on the north face, quickly followed by an ejection on the west face.
FIRST PAIR: Emanates from floors 86, 85. They are visible in the following clips

Note this second clip shows the pair with a third ejection on the west face.
SECOND PAIR: Located 9 floors below the first pair, on floors 77, 78. The folowing clip most clearly shows this second pair (you can also see the first pair, though not very well).

THIRD PAIR: Most clearly visible in the following clip

I would estimate this pair to originate from around the 40th floor.
Three distinct pairs showing the same mathematical and geometric patterns. The only difference between each pair is how far from the corner of the building each ejection appears.
Please note the locations of all core column-to-column welds in this region:
Floors 98, 95, 92, 89, 86, 83, 80, 77, 75, 72....
Let´s also recall curioso number 4 while discussing these ejections.
Curioso #4: The WTC 1 northwest corner was captured very well in video clips during the "collapse" progression. It is possible to study the dust ejection patterns in detail.
The following clip from the BBC allows us to look down the west facade at the collapse front.
It is clear that the visible ejections along the southwest corner (far corner) are preceeding the same ejections along the northwest corner (near corner) by 10 to 20 floors.

and

Therefore, when studying the ejection patterns along the northwest corner in the following video clips, please remember that the collapse progression has already passed these same floors on the southwest corner before these ejections occured.
We established in curioso #3 that this entire west facade is peeling away from the building largely as a single continuous sheet. A few people told me this is "expected" and that the collapse front along this facade is caused by floors failing and piling up on one another.
But that means that, according to them, the southwest flooring is giving way about 10 to 20 stories ahead of the same flooring in the northwest, as visible in the clips linked above.
Within this context lets look at the following video clips:
1) Very good video clip. The camera follows the "collapse" front down the northwest corner. The editor uses slower and slower motion to show dust ejection patterns.

According to NB and Norseman, the very front of the collapse wave is caused by the perimeter columns of the upper block falling within the perimeter of the lower block, thereby severing the collections between the flooring and the perimeter.
This would mean they are severing the flooring from the perimeter along the southern portion of the west facade 10 to 20 stories ahead of the same flooring on the northern portion?
Three distinct pairs showing the same mathematical and geometric patterns. The only difference between each pair is how far from the corner of the building each ejection appears.
The following diagram shows the locations of each of these 6 ejections relative to the locations of core columns. The core column locations are accurate, having been lifted directly from the blueprints. The location of the first ejection on the west side is difficult to locate but it certainly appears where it is marked.
End of curioso number 6.
Now let´s think about what this idea that the upper block acts like a piston actually means.
A piston pushing down on a relatively sealed chamber increases the pressure of the air inside. Assuming relatively constant temperature during this quick process as we apply piston theory to the twin towers and using the ideal gas law, we can see the relatin between pressure and volume wil be P=k/V where k is a constant.
Piston theory as applied to the towers in question roughly assumes
1) The space enclosed by the piston and chamber is an effectively sealed system.
2) The inner plane surface of the piston itself is not parallel to the the open space office flooring before any destruction occurred, but is defined by the very front the collapse wave as seen by the leading edge of the ejections observed on each surface of each tower.
This tells us that, for the North Tower, the south edge of the piston surface leading the north edge by 10 to 20 floors, depending on how far down the leading ejections have progressed.
In the case of the south tower the angle between the surface of the piston and the planes defined by the office flooring before any destruction occurred is even more extreme, since we witnessed quite a tilt in the upper "block". The east edge of the piston surface is clearly leading the west edge.
For now let´s assume that this is a sufficiently sealed system. I personally don´t believe in this assumption, but for the sake of argument I won´t challange it for now.
Various questions naturally arise when trying to explain the "dust" ejections observed by means of piston theory considering the verifiable facts stated above.
Anyone seeing some contradictions here?
