Mine models
Would love to see their model! I'm always impressed by physical mine models since mine are all virtual. Actually, it's hard to grasp just how big underground mines are without some visual reference. I've been in some truly amazingly huge mines in my time. The deepest I've ever been is more than a mile. The mine model in the main office was eight feet tall and had an Empire State Building model at the bottom. It was like 4 inches tall. The elevator ride to the surface took twenty minutes.
The orange one saw a video of one tunnel entrance getting blown up. That as evidence of the underground facility being destroyed is stupid. But, he is.
Here's a nice site of virtual mine models (not mine) for reference:
