In a classic example, a pilot who had received his private pilot license four weeks before and had only 55 hours of total flight experience with five hours at night, took off from San Luis Obispo, California, at 10:35 p.m. He was in the air only about five minutes when he ran into a "wall of clouds." While attempting to return to the airport he impacted a plowed field in a vineyard about four miles southeast of the airport. The pilot survived and, despite serious injuries, was even able to locate a phone in a building at the vineyard and call authorities to report the accident. His passenger, who was his best friend, was killed.
