His parachute suffered what’s called bag lock. The chute is folded, placed in a bag and stuffed in a pack. The static line pulls the chute out of the bag and air inflates the chute to push the bag off. Unless it’s folded wrong and the bag locks. Ordinarily it just doesn’t open. In my son’s case a minor miracle occurred and it opened. Good thing. He had no idea this was going on and didn’t find out until he was safely on the ground.

All that aside - what about the kid’s parachute??? I know nothing about sky-diving, so how does one survive a non-opening parachute?
