APPENZELL, Switzerland (AP) _ Former U.S. national paragliding champion Scotty Marion is missing in the Swiss Alps after taking part in a long distance competition.

Marion, from Salt Lake City, disappeared Aug. 8 after taking off from a launch site in Appenzell, in the eastern part of Switzerland, for a flight that was supposed to last several hours.

Police said it was likely that Marion flew in the direction of south or southwest Switzerland.

A Swiss army helicopter and a Swiss government helicopter, each with an experienced long distance paraglider on board, are being used to search for Marion.

The 38-year-old Marion was U.S. National Paragliding Champion in 2001, and won a World Cup event in Ibaraki, Japan, earlier this year. He works as a paragliding, ski and snowboard instructor. He is safety director of the Utah Hang Gliding and Paragliding Association which regulates the Point of the Mountain paragliding center in Draper.
