Klaus Ohlmann (born June 29, 1952 in Neustadt an der Aisch) is a German dentist and glider pilot who has set several distance records in the Alps and the Andes. In 2003, he flew the second longest distance in cross-country soaring over a freely chosen course, covering 3008.8 km in 15 hours and 17 minutes in Argentina. [1] In 1996/1997, he won the Barron Hilton Cup in the Open Class.
He lives in La Bâtie-Montsaléon in the Hautes-Alpes department, where he operates a gliding center.
Klaus Ohlmann is a four-time world champion in gliding and, with over 60 world records, the most successful glider pilot of all time. The longest glider flight ever recorded, as well as the highest average speed ever achieved of 307 km/h on a 500 km course, have been listed in the Guinness Book of World Records for over a decade. Among these records is also the record for a free distance flight with up to three turning points: On January 21, 2003, he flew 3,009 km from Chapelco Airport in San Martín de los Andes, Argentina, in a Schempp-Hirth Nimbus 4 DM. Just two weeks earlier, on January 9, 2003, he had already broken Hans-Werner Grosse’s 30-year-old distance record with a flight of 2,247.6 km in a Schempp-Hirth Nimbus 4 DM in El Calafate, Argentina.
On February 1, 2014, he became the first glider pilot ever to fly over Mount Everest.
