What happened
Following takeoff, the pilot navigated the glider to an area characterized by thermal activity. After performing several minutes of upper air work, the pilot decided to return to the departure airport.
During the en route phase of the flight, the pilot encountered an area where it was no longer possible to maintain altitude due to the loss of thermal activity. In response to the descending altitude, the pilot selected a nearby bean field for an emergency landing. During the landing roll, the right wing of the aircraft struck a tall plant, causing the glider to ground loop.
The pilot was not injured in the accident.
