Ka 4 Rhönlerche II incident at Stierenberg: pilot parachutes to safety after losing control

On July 30, 1967, a student pilot flying an Alexander Schleicher Ka 4 Rhönlerche II experienced an incident near Stierenberg, Switzerland. After releasing from the towplane, the pilot encountered good thermals but inadvertently entered a cloud, losing control of the aircraft. The glider suffered structural damage, prompting the pilot to bail out using a parachute. The pilot landed safely on a forest path with no injuries, while the glider was heavily damaged upon crashing into trees. No third-party damage occurred.
