What's the point of wearing a helmet when skydiving? If your chute doesn't open, are you supposed to try and land head first so it will protect you? π€
So if you crack your head jumping out you are still awake enough to pull the cord, plus if you land hard you don't smash your head on a rock.
The super high altitude jumpers had altitude devices that would automatically deploy their chutes in the event that their air supplies failed and they passed out.
