The Rolladen-Schneider LS1 is a Standard Class single-seat glider manufactured in Germany by Rolladen-Schneider from 1968 to 1977.

The World Gliding Championships (WGC) is a gliding competition held roughly every two years by the FAI Gliding Commission. The dates are not always exactly two years apart, often because the contests are always held in the summer in either the Southern Hemisphere or Northern Hemisphere.
