What happened
The pilot departed on the cross-country flight in the experimental airplane without filing either an instrument or visual flight plan. The route of flight would have taken him over high mountain passes, which were obscured by clouds at the time. An alert notice (ALNOT) was issued after family members reported that he had not arrived at his planned destination. A search and rescue mission was subsequently initiated, and for the following 6 days multiple search sorties were performed. To date, the airplane has not been found.
