The ESG-29 is a single-seat primary training glider from 1929 that flew in many countries. Large numbers have been built, also by gliding clubs. It had the nickname "Schädelspalter" (skullsplitter) because of the strut in front of the pilot, but no such occurrences have been reported. The one seen here is an airworthy replica built by Klaus Heyn and handed over to the Deutsches Segelflugmuseum at Wasserkuppe in 1988.
