After a period of wrangling and increasing public interest in the novelty of this new 'extreme' form of ski jumping, the FIS relented. In 1938, a decision was made at the fifteenth International Ski Congress in Helsinki, Finland, to allow for "experimental" hill design, thereby officially recognising ski flying as a sanctioned discipline. Despite this reluctant recognition, the FIS still frowned upon the practice of aiming predominantly for long distances over style, and to this day refuse to publish lists of world records in an official capacity. Furthermore, the rules for ski flying would not be fully established until after World War II.
