Overview
A glider pilot returning from a soaring flight was unable to visually locate the destination airport. In an attempt to navigate using GPS, the pilot mistakenly selected a different airport in the unit. As the glider's altitude decreased, the pilot opted to conduct a forced landing in an open field.
Navigational Challenges
Upon attempting to return to the airport, the pilot found that visual acquisition was not possible. Consequently, the pilot turned to the GPS unit for assistance. However, during the process of selecting a waypoint, an incorrect airport was chosen. This error led the pilot away from the intended landing site.
Emergency Landing
With the glider's altitude continuing to drop, the pilot made the decision to land in a field. The glider touched down, but during the landing rollout, it encountered a ditch. The glider came to rest in an upright position.
