'''The Zurich Airport Skymetro ''' is an underground airport people mover at Zurich Airport in Switzerland. The long system connects the airport's main Airside Center with its mid-field Terminal E, passing underneath Runway 10/28. The line opened in September 2003, and was constructed by the Otis Elevator Company.
As of 2010, Skymetro was carrying 6.73 million passengers per year, and is claimed to be the most used cable way in Switzerland. With a cost of 176 million Swiss francs it is also the most expensive cable car system and one of the most complex with high safety standards.
The tunnels of the Skymetro are equipped with Zoetrope-like films displayed on the sides, with each film consisting of a series of still frames in rapid succession, accompanied by matching sound effects played over the vehicles public address system. Over time, various films have been shown, including ones based around the fictional character Heidi and the Matterhorn mountain. However, as of late 2012 these films are no longer displayed. Instead, two new films have been made for the system. The first of the two new films shows a mid-aged woman (holding an ice axe), and her younger son (holding an apple) appeared as of late 2012, while the other replacement film shows a man waving the flag of Switzerland.
