While being towed to the planned launch height, the glider under tow and another glider in the circuit area, collided. The collision caused the tow rope to break and the pilot of the glider, although injured, was able to land his aircraft. The tailplane of the other glider separated in the collision and the aircraft descended uncontrolled into the ground. The tug aircraft was undamaged and landed safely. The glider rejoining the circuit approached the tug and glider under tow from the right rear quarter. Immediately prior to the collision, witnesses reported that the glider attempted avoiding action. The reason the pilot did not see the two other aircraft until it was too late to successfully take avoiding action, could not be determined. However, the combination of a broken cloud cover and a mottled background would have made the pilot's task more difficult.
