5 things you didn't know about Denver International

Verified by the CompareFlights team
  1. 1DEN was deliberately built 25 miles northeast of downtown so the airport could expand without urban encroachment — it currently has 6 runways and the master plan supports up to 12, more than any other US commercial airport.
  2. 2The 32-foot Blue Mustang sculpture by the entrance — nicknamed 'Blucifer' — killed its own sculptor Luis Jiménez in 2006 when a piece fell on him during construction. Locals consider it the airport's mascot.
  3. 3DEN's white tented roof was designed by Fentress Architects to evoke the snow-capped Rocky Mountains visible to the west — and it's so reflective that it's visible from the International Space Station.
  4. 4DEN has the longest commercial runway in North America at 16,000 feet (3 miles) — long enough to accommodate any aircraft ever built, including emergency Space Shuttle landings.
  5. 5DEN's elaborate underground tunnel network (built for the people-mover system) and a controversial 'New World Airport Commission' dedication stone have made it a magnet for conspiracy theorists since opening in 1995.
