Reno, Nev. (AP) A search is under way for a small plane carrying aviation adventurer Steve Fossett.
Federal officials say he took off in the single-engine plane Monday at a private airstrip in western Nevada, and didn't return as scheduled.
A friend reported him missing.
Fossett is a part-time Colorado resident, and maintains a home in Beaver Creek. A telephone message by the Associated Press left for a Peggy Fossett in Beaver Creek was not immediately returned. Steve Fossett is married to the former Peggy Viehland of Richmond Heights, Missouri.
The Federal Aviation Administration says the Civil Air Patrol is taking part in the search. It's being made more difficult because Fossett apparently didn't file a flight plan.
In 2002, Fossett became the first person to fly around the world alone in a balloon. He had made five previous attempts.
Three years later, he became the first person to fly a plane solo around the world without refueling.
He and a co-pilot also claim to have set a world glider altitude record of more than 50,000 feet.
Fossett is listed as president of Larkspur Securities, an investment firm in Chicago, and is referred to on his various mission web sites as a “Chicago businessman.”
Chicago also is listed as his hometown.
