Search teams in Nevada have resumed the hunt for missing aviator Steve Fossett based on new information found in an analysis of radar data.

Searchers on the ground and in airplanes focused Sunday on a section of rugged terrain in western Nevada.

Fossett has been missing since he took off on September 3 in a small airplane. A formal aerial search for him was suspended on September 19, but officials said they would resume the search if they got any workable leads.

Fossett is well known for his record-setting solo flights around the world by both balloon and airplane. He also swam the English Channel, competed in the Iditarod sled-dog race and scaled some of the world's best-known mountain peaks.
