An investigation into the underground tunnels of DIA

For years, rumors and urban legends have circulated about what actually happens under Colorado's largest airport.

DENVER — Thousands of people travel through Denver International Airport every single day.

Traveling through the airport can be a little, out of this world.

"I got lost. I didn't realize I had to take a train," said traveler, Sebastian Talarico. 

Theories have circulated for decades about what actually happens in the tunnels below the airport. Many of the theories involved extra terrestrials, lizard people or a secret city. None of which will not be found in these tunnels. Well, sort of.

"It's a lot of luggage down here," Stephanie Figueroa with Denver International Airport said.

The paths that go along the tunnels do resemble busy city streets. In the tunnels, ramp workers and airline crews make their way through golf cart traffic to deliver bags and other equipment.

"That's all it is, luggage tags, maintenance workers and lot and lots of ramp workers" Figueroa said.

Some conspiracy theories allege that the tunnels connect the airport with Cheyenne Mountain about 100 miles away in Colorado Springs. Others claim that they’re underground bunkers that will be used by the world’s elite when the apocalypse comes (the original theory was that that would happen in 2012, which we can definitively say was false).

There are remains that can be found in the tunnels. No, they are not remains of a being from outer space, but the remains of the state-of-the-art automated baggage system that ultimately failed and was abandoned in 2008.

Some conspiracy theorists believe the automated baggage system's bungled implementation was meant to be a disinformation tactic to divert eyes away from what’s really happening at DIA.
