The number of paragliding accidents is growing up exponentially. We review in this study 39 paragliding accidents which occurred 1985-1987 in the Val d'Illiez (Switzerland). The REGA (Swiss air ambulance) rescued 1987 61 pilots, which are also included. Most of the accidents were related to a mistake of the pilot. None is due to a failure of the material. The most severe injuries occurred immediately after taking off. The most frequent injuries occurred during landing. There is a correlation between the altitude, the wind velocity and the severity of the injuries. The lower extremities and the backbone are often injured, which is explained through the axial trauma. The pilots need a better training programme, the performance of the material should be built up and the starting places should be equipped.
