"Wingsuit deployments are perhaps one of the most complicated tasks in skydiving. The transition from wingsuit flight to parachute flight is complex and fraught with hazard, and it is worth studying.
The current trend in wingsuit design is toward more efficient and powerful designs that are capable of higher forward speeds than we have seen before. This translates to higher risk for pilots who are not training to proper technique.
One of the most prevalent issues currently, is deploying at too high an airspeed, which can cause damage to equipment, damage to the pilot himself, and encourage violent off-heading openings which can lead to severe line / body twists.
