Noriaki Kasai of Japan became the oldest winner of a ski jump World Cup competition at the age of 41 after upsetting the favourites in Austria on Saturday.
Kasai had jumps of 196 and 197 metres and earned 391.6 points for his 16th career victory but first in almost 10 years. His last win came in Park City, Utah in 2004.
Peter Prevc of Slovenia had 381.5 points in second place, and defending overall World Cup champion Gregor Schlierenzauer of Austria was third with 380.3.
The event was overshadowed by Thomas Morgenstern's crash during training on Friday.
The Austrian suffered skull and lung injuries but was in stable condition in a Salzburg hospital Saturday.
Another ski flying event on the Kulm hill is scheduled for Sunday.
