| Additional details: | None | 
The pilot stated that after his Schleicher ASK-21 glider was towed aloft to 2,000 feet and released, he flew too far from the airport traffic pattern. He said that during the return to the airport, he encountered a "sink and waterfall" effect, which caused a low approach, resulting in his inability to make it to the airport. Subsequently, there was a collision with terrain 100 feet short of the runway. The pilot added that there were no deficiencies with the performance and handling of the glider.
The glider pilot's misjudged distance/altitude while soaring.
