Ka 2b collision with power line near Rifferswil during aerotow launch

On August 14, 1966, an Alexander Schleicher Ka 2b experienced a collision with a power line shortly after takeoff near Rifferswil, Switzerland. The glider, with a pilot and passenger onboard, was being aerotowed when the dive brakes inadvertently deployed, leading to a loss of altitude. The pilot released the tow rope to avoid endangering the tow plane but was unable to avoid the collision. Both occupants sustained serious injuries, and the glider was severely damaged. The incident interrupted a local power line, causing additional third-party damage.
