From its beginnings in the 1930s, ski flying has developed its own distinct history and since given rise to all of the sport's world records. The first hill designed specifically for ski flying was built in Yugoslavia in 1934, after which both Germany and Austria built their own hills in 1950. This was followed by Norway in 1966, the United States in 1970, and Czechoslovakia in 1980. From the 1960s to 1980s, a friendly rivalry between the European venues saw world records being set regularly, together with hill upgrades and evolutions in technique to fly longer distances.
