As I've explained to Chris many times, his image "southcorestands" shows part of the north tower's core. Every single time I've quizzed him on which tower was pictured in a photo I've presented he's gotten it wrong.
After years of "research," he doesn't even know which tower was where on the site. It doesn't get much worse than that.

In the photo above, note the 16-inch wide tongue-in-grove gypsum panels that comprised the core walls. Chris cannot explain how the gypsum survived while a 17-foot thick concrete wall was blown to smithereens around it.
