The top image in OP is from DIA. Here are some more.
The New World Airport rabbit hole is an interesting one.
For noobs: Essentially DIA was built despite the fact that Denver already had a functional airport (Stapleton). The project cost a lot more than it was supposed to, has a Masonic plaque/time capsule beneath the security checkpoint, and has a "baggage system" underground which never worked. Multiple structures were put on the site and then buried, with the claim that they hadn't been placed correctly.
The New World Airport Association, which dedicated the airport, does not exist in any other capacity– open source, anyway. And then there's old Blucifer.
A worthy dig, but one full of disinfo. (((They))) have known we know about that creepy airport for a long time.
