The glider pilot stated that he intended on attempting the Federation Aeronautique Internationale (FAI) gold badge distance of 300 kilometers (186.42-mile) cross-country flight. He also stated that he felt pressure to fly first. The glider was towed aloft to 2,000 feet mean sea level, and released. He flew to the north side of a ridge and found lift, then flew south toward the airport in an effort to stay closer to it, intending on finding lift before proceeding. While approaching the ridge he encountered sink, and elected to cross the ridge. He crossed the ridge at approximately 300 feet above ground level and he could see the airport, but was unable to reach it. He maneuvered the glider for a landing into trees along the ridge. There was no preimpact mechanical failure or malfunction with the glider. The pilot later stated he should have landed in fields in the valley.
