From Masonic symbols and demonic horses to secret underground bunkers and lizard people, Denver International Airport (DIA) has cemented its place in modern mythology. But what's the real story behind the world's most mysterious airport?

In this deep dive, we're taking you on a journey through DIA's most persistent conspiracy theories. We'll start with the airport's troubled birth, revealing how a colossal $2-3 billion budget overrun and a catastrophic baggage system failure created the perfect breeding ground for public suspicion.

Then, we'll peel back the layers of lore, from the infamous dedication capstone and its "New World Airport Commission" to the bizarre claims of OAG inscriptions and swastika runways. For each theory, we’ll uncover the surprisingly mundane or more intriguing facts behind them, from the truth about the "New World" homage to the Freemasons to the artistic inspiration behind the menacing "Lucifer" statue.

We’ll dive deep into the mysteries of the underground tunnels, separating the fact of their existence from the fiction of hidden military bases and alien life forms.

But the most remarkable part of this story is DIA's audacious response. You’ll learn how the airport transformed a PR nightmare into a masterful marketing strategy, embracing the rumors with a playful, tongue-in-cheek campaign. From posters asking "Construction or Cover Up?" to a talking gargoyle and a dedicated "Den Files" website, DIA has proven that when you can't fight the madness, you might as well join it.

This episode is your shortcut to being well-informed on the myths, facts, and genius marketing behind Denver International Airport, and it will fundamentally change the way you see this modern wonder.
