Narrative:
The pilots of two gliders (Glasflugel Standard Libelle VH-GXY and Schleicher ASW.15 VH-GGV) were competing in a triangular navigation exercise and were in the vicinity of the final turning point. The aircraft were orbiting in a thermal when they collided at a height of about 3,500 feet above the ground at Tungamar, 13 km South South West of Yarrawonga, Victoria. Both aircraft became uncontrollable and the pilots parachuted to safety.

The ATSB investigation established that both aircraft were orbiting to the right when they collided. Examination of the wreckage showed that the right wing of VH-GXY hit the left wing of VH-GGV. The impact was on the leading edge of each wing. About two metres of the wing of VH-GXY was severed, and about one metre of the wing of VH-GGV. Neither pilot had been aware of the presence of the other aircraft in the thermal.
