makes some sense...

"There are several conspiracy theories relating to the airport's design and construction such as the runways being laid out in a shape similar to a swastika. Murals painted in the baggage claim area have been claimed to contain themes referring to future military oppression and a one-world government. However, the artist, Leo Tanguma, said the murals, entitled "In Peace and Harmony With Nature" and "The Children of the World Dream of Peace," depict man-made environmental destruction and genocide along with humanity coming together to heal nature and live in peace.[70]

Conspiracists have also seen unusual markings in the terminals in DIA and have recorded them as templar markings.[71] They have pointed to unusual words cut into the floor as being Satanic, Masonic, or some impenetrable secret code of the New World Order: Cochetopa, Sisnaajini and Dzit Dit Gaii.[72] These words are actually Navajo terms for geographical sites in Colorado. "Braaksma" and "Villarreal" are actually the names of Carolyn Braaksma and Mark Villarreal, artists who worked on the airport’s sculptures and paintings.[73]

There is a dedication marker in the airport inscribed with words, "New World Airport Commission". It also is inscribed with the Square and Compasses of the Freemasons, along with a listing of the two Grand Lodges of Freemasonry in Colorado. It is mounted over a time capsule that was sealed during the dedication of the airport, to be opened in 2094. The Freemasons participated in laying this “capstone” (the last, finishing stone) of the airport project.[72]

Robert Blaskiewicz writing for Skeptical Inquirer Magazine states that conspiracies about the airport range from the "absurd to the even more absurd". When asking airport media representatives, 'what conspiracies are associated with the airport', they responded, "You name a conspiracy theory and somehow we seem to be connected to it." Blaskiewicz found that contrary to claims from conspiracy theorists that DIA will not discuss these stories with the public, they also give tours of the airport.[74]"
