Points are awarded for distance and style by five judges, with competition sanctioned by the International Ski Federation (FIS). To enable the athletes (who are known as "ski jumpers") to effectively glide such long distances and land safely, the skis they use are considerably wider and longer than their cross-country and alpine skiing counterparts. Ski jumping is predominantly a winter sport and has been part of the Winter Olympic Games since its inception in 1924 for men and since 2014 for women. Since 1954 it is possible to ski jump in summer on artificial surfaces made from plastic. Along with cross-country skiing, ski jumping is one of two sports which form the Nordic combined discipline. Holmenkollbakken in Oslo is the holy place of this sport, which is most popular in Austria, Germany, Finland, Japan, Norway, Poland and Slovenia.  - The 1992 FIS Ski Flying World Ski Championships took place on 21 March 1992 at erák in Harrachov , Czechoslovakia for the second time .
