The Federal Aviation Association put guidelines on skydiving in the 1930s. The FAA still regulates aircraft, but skydiving as a whole, is not regulated. Neslin and Clark said he preferred that the FAA not interfere with the sport itself, but would like to see more safety inspections of jump schools. Although there is no formal regulation of skydiving schools, many schools follow guidelines set by the United States Parachute Association. Every movement you are doing is against that wind.
Parachutists check and recheck their gear before climbing into the plane.
A backup parachute is standard in every pack. During the classes, the instructors take students through videos and scenarios of what they should expect. More often than not, the most common accidents lead to sprained ankles. It's that they've done something stupid. Even the accident outside of Tooele in January that claimed the life of nine skydivers, was not related to skydiving, but their plane.
