Two gliders collided mid-air, resulting in a crash of one glider. Both occupants in the glider died in the crash.
The other glider (HA-5501) managed to land but sustained substantial damage.

The IC concluded during the investigation that the causes of the occurrence were as follows:
- The crew of Aircraft 1 either did not see Aircraft 2 or if they saw it, they failed to perform an avoidance manoeuvre in time.
- The pilot of Aircraft 2 had not seen Aircraft 1 for a long time until the collision.
In addition to the above, the IC presumes the following probable causes:
- The colour combination of the two aircraft was a contributing factor in the given meteorological and light conditions. The painting of both sailplanes included a colour combination dominated by several shades of blue and the silver colour, so both sailplanes could have blended into the blue sky as background.
- The behavioural and physiological factors originating in the age of the Flight Instructor might also have been contributing factors.
