America Declassified: Denver Airport, NSA Photos

From Denver airport’s secret bunker to the NSA’s new data center, our investigators are on a mission to find out the truth.

Could Denver International Airport, America’s largest airport, be hiding a secret underground bunker the size of a city -- built in case of a nuclear holocaust?

A commemorative stone marker inside the terminal of Denver airport says that the airport was funded by the New World Airport Commission. Could this be code for the Freemasons, the notoriously secret society that’s a big focus of the New World Order conspiracy theory?

Investigative journalist Jeanette Pavini attempts to decipher the airport's disturbing artwork, scattered throughout its terminals.

This mural inside Denver airport is believed by some conspiracy hounds to prophesize the coming apocalypse -- and an America living under martial law.

Things at Denver airport get even weirder: There are reports of regular sightings of UFOs in the skies near the airport. There are even multiple pieces of video evidence of these sightings.

Geoscientist Ben McGee obtains unprecedented access to the White Sands Missile Range in order to look into the wild internet rumors that surround the site -- and hopefully reveal secrets concealed there for decades.

At the White Sands Missile Range, there seems to be a ghostly battleship deeply camouflaged within the landlocked desert's live bombing range. Ben, armed with an array of scientific gadgets, is on a mission to unearth restricted artifacts from what could be the deadliest spot on the planet.

Right outside of Bluffdale, UT, between Utah Lake and Great Salt Lake, the NSA is building a new, massive data center. But why?

Could the NSA be building this data center to store everyday American citizens’ private information? While its stated purpose is to support the Comprehensive National Cybersecurity Initiative, its exact mission is classified information.

This peek into what the NSA Data Center could look like offers an idea of the massive amounts of information the center could potentially process.
