There's a conspiracy that an airport has an underground facility or base bunch of tunnels, something like that, but I'm not sure if it's the Denver airport might be the Chicago one.

This was only created AFTER humans bore into earth reviving the replica of power generation we are just beginning to refind present-day underneath egyptian pyramids. So, Wait about 20more years for the nee world airport commission & dont mess with stuff meant for people of the future. Or else....
