In a first of its kind jump, a daredevil skydiver on Saturday became the first to jump from a height of 25,000 feet (7,620 meters) without a parachute, landing in a net in southern California. Luke Aikens, 42, who has 18,000 jumps under his belt, completed the jump in Simi Valley, landing in a net measuring 100 feet by 100 feet.
