The aim of this study was to determine how risks associated with skydiving can be managed within acceptable limits. Using “Course-of-Action” theory described by Theureau, four experienced skydivers viewed recordings of their jumps, from preparation to landing, to elicit their perceptions of these experiences. The sequences dealing with safety concerns were then extracted. Data analysis revealed seven typical sequences of activity to manage safety, labeled “To check the material during preparation,” “To feel prepared and safe for the jump as the plane gains altitude,” “To use the time of freefall,” “To deploy the parachute,” “To fly safely,” “To ensure a safe landing” and “To organize the structured packing of the parachute.” These results showed how the skydivers mitigated safety risks through a heightened awareness of critical elements in the unfolding jump activity and sequences of distributed and timed concerns and actions. The implications for accident analysis, prevention and education for training in risky sports activity are provided.

• The skydivers’ activity could be broken down into seven safety sequences.

• Each safety sequence was defined by specific involvements and directions at the very moment of the situation.

• Skydivers’ safety concerns are embedded in the succession of two types of temporal horizon organization: immediate and short-term.
