The issue of safety in ski flying had resurfaced. In only a single day at the aforementioned 1983 event, the hill in Harrachov – a location named "Devil's Mountain" – became notorious for causing many violent accidents. Horst Bulau crashed and suffered a concussion, while Steinar Bråten and Jens Weißflog also crashed. Tapio Mikkonen crashed heavily in 1980, as did Ploc in 1985 and Iztok Melin in 1989. All escaped serious injury, but it was a chilling precursor of more to come.
