In 1998, Robert Jasper opened a new mixed route on the Breitwangfluh in the Berner Oberland: four pitches across the ceiling of a huge cave, bolts only on the belay station, classified as M10 and E4 – the first route in the world of this difficulty degree. Only in January 2006, this route was successfully repeated in its full length. On February 10, 2006, Beat Kammerlander climbed this line red point - without installing any belays beforehand. Four days later he climbed again the route with the name "Flying Circus".
