In the aftermath of the Planica event and following numerous near-flat ground landings, it became clear that ski flying had once again outgrown an older hill and needed enlarging in the years to come. In 2005, almost immediately after the conclusion of the World Cup season, talks were under way to upgrade the hill in Vikersund. This became a reality in mid-2010, when the FIS announced major rule changes at the 47th International Ski Congress in Antalya, Turkey, to allow for ski flying hills to be constructed to their largest sizes yet.
