The pilot was approaching to land at the end of a soaring flight. There was turbulence in the circuit area, with a moderate crosswind for the landing direction. The pilot realised he was overshooting his planned touchdown point, and side-slipped the glider to lose height. At the conclusion of this manoeuvre the glider was some 1000 feet in from the threshold. It then landed heavily and bounced, before a second heavy touchdown occurred. The pilot had evidently been distracted by the presence of another glider and a tug aircraft at the strip threshold, and probably by the wind strength and turbulence.
