 Different packing methods of the reserve parachute affect its deploying time.Low-altitude wing failure can result in serious injury or death due to the subsequent velocity of a ground impact where, paradoxically, a higher altitude failure may allow more time to regain some degree of control in the descent rate and, critically, deploy the reserve if needed.In-flight wing deflation and other hazards are minimized by flying a suitable glider and choosing appropriate weather conditions and locations for the pilot's skill and experience level.
