High Quality Content by WIKIPEDIA articles! Air time is the feeling of weightlessness or negative gravity force experienced on a roller coaster or other amusement rides. On roller coasters this feeling is usually achieved by the train going over a hill. Hypercoasters such as Magnum XL-200 at Cedar Point and Bizarro at Six Flags New England are known for their large amounts of air time. In addition, many wooden roller coasters, such as Balder at Liseberg, The Voyage at Holiday World, and Shivering Timbers at Michigan`s Adventure are known for their air-time.
