Burkhart Grob G102 Club Astir IIIB
The glider ground looped during an off-airport landing after contacting high vegetation. The pilot reported he encountered a strong and prolonged downdraft, which resulted in the glider not maintaining altitude. Because of the loss of altitude, the pilot elected to perform an off-airport landing. During landing, the wingtip of the glider contacted vegetation, which resulted in a ground loop and the glider impacted terrain.
