I am getting sucked in again - against all of my principles of not getting in disputes with people undeniably certifiable ;-). This is not an attempt to convince the OP about anything. I do can identify the border between "feasible" and "futile"

. I am doing this purely as a mental exercise in logic.
So, we have an irrefutable evidence a plane hit the building. There is a whole mountain of evidence supporting it. We know which plane it was, we know who was in control, we know how they got aboard, we can explain virtually all what happened during and after the impact. Any attempt to dispute this evidence is ridiculous and destined for failure.
The only "serious" piece of "evidence" conflicting the above is a piece of aluminium cladding that seems to defy the straight logic. So, let's try just a straight logic to explain what we see. It is like watching a magic show. For a hour or so you are watching stuff you KNOW is entirely impossible. But is is happening, right? Yes, because you are missing the background of the tricks.
So, we know the cladding
wasn't in its original position when the column behind it has been severed. I agree with the OP on that point. All the analogies with broken bones etc are valid in general, but they don't really fit to the
exact situation we are having here. So, a sequence of events is becoming to emerge: the first part of the wing damaged the cladding and cause the top end to disconnect from the structure. The next part pushed the cladding aside (possible due a hydraulic action in the fuel tank) and it starts falling down pivoting around its bottom attachment. The wing comes apart (possibly again due to the hydraulic action) at the point of the column on the right, leaving it and our cladding now in front of it relatively undamaged, while the other columns were being severed. The tail section of the wing has arrived containing whatever part has "drilled" the circular hole in the column on the right, giving a glancing blow to our cladding bending it back up (the bend near the bottom of it supports this part) and moving it back left to its original position.
Possible? Yes. Likely? No. But have you ever heard about people winning first division in lottery twice in a row? Possible? Yes. Likely? No. Did it happen? Yes.
What I am presenting is probably only one of the possible scenarios and there may be others - similarly unlikely but plausible explanations. Every each of them will be many times more probable than the sick fantasy the OP is trying to sell us. There is no point whatsoever trying to find some truth in these.
