Zooming in on the pile we get:
In the above close-up we see what appears to be an air conditioning unit from the penthouse roof surrounded by what looks like a ventilation fan, two parapet blocks, an anchor from the roof, and possibly the bottom of another anchor from the roof. There are probably a lot more parapet blocks under the pile, but one cannot be sure if just a few blocks fell or if the entire parapet fell. In the upper right there is another man-made object with sharp sides, but it is impossible to tell what it is. The following photo shows a close-up of the same pile from a slightly different angle.
In the above close-up we see what appears to be the same air conditioning unit from the penthouse roof with another air conditioning unit above it, with what looks to be a ventilation fan to the left of it, along with an anchor from the roof and the white arrows pointing to two parapet blocks. This time, however, we can see a hexagonal object with a pole protruding from it which may be the bottom of a deck table along with the mast for holding the sun shade. Again, at the upper right there is another man-made object with sharp sides, but it is impossible to tell what it is.
Looking at the same pile from 90° to the right, we see:
Zooming in on the pile again, we see the following closeup
In the above close-up, on the left at the top of the pile we see what appears to be the same air conditioning unit from the penthouse roof that we saw in the earlier close-ups. This time, however, it is clearly distinguishable. On the right hand side of the pile we can vaguely see more two man-made objects. The one on the top appears to be another air conditioning unit from the penthouse roof. The one at the bottom may be yet another air conditioning unit from the penthouse roof. The lightly colored rectangular frame lying over the bottom one may be the frame that held the two units when they were on top of the penthouse roof.
All of these units appear to be displaced from their original landing points on the floor of the parking basement because of the actions of the recovery crew that obviously cleared the basement floor. However, the fact that they have left the objects in this pile behind while clearing everything else appears to show that they believe these objects to have a special importance. So they are leaving them in place temporarily until someone else can inspect them.
What I infer from these objects being found on the floor of the parking basement and being left behind temporarily by the recovery crew is that these objects clearly fell from the penthouse roof before any buildings started to fall down and before the pool deck fell down. In other words, the falling of these objects from the penthouse roof was the trigger that started everything that followed, including punching a small hole in the deck, taking out one or two horizontal support beams between columns C27 and M11.1, which then caused column 27 to buckle, which probably caused the two adjacent columns to buckle also, bringing down the entire middle section of the buildings, then bringing down the other two sections of the building, and then causing the rest of the pool deck to collapse. These photos are as close as one gets to a confirmation of this general narrative.
Now we must determine why the penthouse roof fell down to start the entire sequence of events. This appears to be why Allyn Kilsheimer and his company KCE are taking cores from the penthouse and higher floors of Champlain Tower North.
