Schempp-Hirth Discus A, LB (Italian), Schempp-Hirth Discus A, VH-GSO, 7 km NE Deniliquin NSW, 29 January 1987

The pilots were competing in a race as part of the World Gliding Championships. The gliders were in a group climbing in a thermal, when they collided at about 3900 feet above mean sea level. The Italian pilot in LB did not see the other aircraft, while the Polish pilot of VH-GSO only became aware of the proximity of LB at the last moment. The collision severed the right half of the horizontal stabiliser of LB, however the pilot was able to retain control of the aircraft and landed without further damage.
