All these increasingly long distances came at a price, as illustrated by filmmaker Werner Herzog in his 1974 documentary "The Great Ecstasy of Woodcarver Steiner". During both the aforementioned events in Oberstdorf and Planica, several athletes including Steiner had far exceeded the limits of the hill by 'out-jumping' it or simply 'running out of slope'. Jumps were much further than in the 1950s, during which the old Kongsberger technique was still in use. The results were now potentially fatal each time: athletes were coming only metres away from landing on completely flat ground, or the equivalent of falling from a multi-storey building (albeit with forward momentum). Furthermore, only a wool cap and goggles – or no headgear at all – were worn; an antiquated feature left unchanged from the very earliest days of ski jumping more than 150 years prior. In 1979, at their 32nd International Ski Congress in Nice, France, the FIS mandated helmets to be worn by athletes at all ski jumping and flying events.
