Accident with the glider SE-TRI of the type Rolladen-Schneider LS1-F, at Enköping/Långtora aerodrome, Uppsala County

In connection with a glider take-off with a tow aircraft, the pilot in the glider perceived that the towing aircraft began to fall and therefore disconnected the glider and turned back for landing. In the turn, the glider sunk through and hit the ground with one wing, which led to the aircraft's rear body breaking apart just behind the wing bracket. No personal injury occurred.
