Landing an airplane is the same, whether you have an engine or not, but in soaring you only get one shot at it!! Most pilots use a circuit to align themselves with the runway they want to land on. They fly parallel to the runway (downwind leg), then turn across the end (base leg), and then turn final and begin their approach. As the sailplane is already descending the pilot only has to modify his descent rate using dive brakes or spoilers. The pilot has to correct for drift due to cross-winds and once done, the pilot will flare the plane and then touch down onto the runway. Momentum ensures that the plane rolls evenly on its main wheel. Only when the plane stops rolling does a wing gently touch the ground.
