Pilatus B4 accident during approach at Les Eplatures, Switzerland

On August 5, 1990, a Pilatus B4 glider crashed during an approach to an outlanding near Les Eplatures aerodrome in Switzerland. The pilot, aiming to return to Courtelary after an earlier flight, encountered insufficient altitude to reach the airfield. While attempting an emergency landing, the pilot noticed a high-voltage line too late and executed an evasive maneuver. This resulted in a stall and crash from a low height, causing serious injury to the pilot and destroying the aircraft.
