The pilot took off, assisted by an aerotow, from the Soesterberg glider airfield in a single-seat glider. The extendable turbomotor on the glider was unusable due to a technical problem. After having flown for about 1.5 hours, and having returned early because he had not found any more thermals, the pilot decided at an altitude of approx. 300 meters to make an off-field landing near Elst. Landing options were limited there. The pilot chose the most suitable field, with a length of approximately 300 meters, for a landing. He flew a left-hand circuit and on final approach selected flaps in the landing setting. He assumed that the wind was approaching from the right during the landing.
The field rose in gradual undulations in the direction of the landing. During the ground roll, whereby the airbrakes were opened, according to the pilot, the glider failed to lose sufficient speed. Approximately 50 metres before he reached a row of trees, he initiated a ground loop estimating that the glider could not be stopped before it reached the end of the field. The glider sustained damage to the fuselage, the horizontal stabilizer and the landing gear. The pilot was unharmed.

The glider landed on a heading of 015. In the vicinity of Elst, at an altitude of 500 feet, the wind was blowing from 150 degrees (south-southeast) at a speed of 13 knots.
The glider experienced a tail wind component, resulting in a rise in ground speed. This extended the distance the glider covered during the roll-out after landing, before it came to a stop. The glider could not be stopped in time. Given the wind direction, which the pilot had failed to recognize, the field the pilot selected turned out to be less suitable for the off-field landing.
