The more pictures they put out, that everyone is saying looks like drone footage, the more obvious it becomes that it's a broken wall.
You can see cracks in the concrete in the lower portion of the picture.
This one looks like it has exposed rebar.
It's starting to look more like it's going to be a logo or wording in a destroyed wall. At least that's my thoughts. I could be completely off and it is drone footage, though.
