Research the geography of San Marino and Monaco including the ground below it.
Not easy to dig in stones. I understand the tunnels built for communication, using mine workers, TNT and special drilling heads used, but it’s usually a huge project.
A storage for content of 600 planes? That’s way bigger.
How many planes would fit 1 tunnel?
How many more tunnels needed?
Imagine the scale of it. Does it still look real? Or 600 is just a mistake.
One tunnel under Monaco that I saw was about 4 highway lanes wide with a ceiling about 25-30 feet above the roadway. It appeared to have been cut directly through solid rock.
Thanks for rising an interesting point.
