Ole was to learn skydiving. He was told that shortly after jumping out of the plane he was to pull the short rip cord and that will open a small parachute which will open the large chute and if by chance the large chute fails to open, he should pull the other cord which will open the large parachute. He was told that a car will be on the ground to take him back to the airport.
