At approximately 06:30 PST, a Cessna 150G struck power lines during an attempted emergency landing on the southbound lanes of Interstate 5 about four miles north of Marysville. The unlicensed pilot, who was the sole occupant, was killed. The owner of the airplane said it had been stolen from Arlington Municipal Airport about three to four minutes prior to the accident. Witnesses saw the aircraft descending toward the west about two miles south of Arlington Airport. As it came over the highway, it descended toward the southbound lanes like it was going to land. The airplane struck power lines about 45 feet high and dove steeply to the ground.
