Analysis

The glider was departing on runway 27 for a local pleasure flight. During the towed takeoff, the tow rope broke at 220 feet above ground level. The pilot cleared the tow plane by making a right turn and then turned back to the left to the departure field. Due to obstructions near the runway, the pilot elected to land on the grass on the left side of the paved runway. After touchdown, the glider struck a mound of dirt which destroyed the airplane.
