SPSJ is dedicated to enhancing sport parachuting safety by disseminating information about equipment, environments and human factors. Safety is the most important aspect of intentional jumping. Parachuting can only survive by maintaining an excellent safety record. Growth depends upon improving our safety standards. Jumpers can attest to the fact that the opposite is true.
Most jumpers have excellent survival skills.
However, skydiving is risk-taking. The knowledge is used to mentally and physically rehearse the planned dive sequence. Additional knowledge is required to react to unplanned events that may occur. A simulated scenario is created when a person is in a hanging harness, but actual skills are learned which should be used again if an actual dive presents a similar situation. Jumpers also simulate body movements for freefall maneuvers during dirt dives and then perform similar motions on a real jump.
