John put his arms and legs into his jumpsuit and zipped it up. He climbed aboard the airplane with the other passengers and their instructor Zane. The small aircraft took off into the air, and John could feel the excitement inside the cabin, with everyone chatting nervously as the aircraft ascended. This was his third time skydiving, and John felt almost like a pro at this point. A few of the other passengers were doing this for the first time, however, and they asked their skydive partners lots of questions. The first-timers were required to have a partner, who would be strapped to their backs with a parachute.
John remembered his first time, several months ago. He was the youngest person in the group, but he was definitely not scared. John had bungee jumped, gone scuba diving, and competed in motocross races. Skydiving was just another way to achieve the adrenaline rush he craved.
As the airplane reached an altitude where the passengers could safely skydive, the girl sitting next to John leaned toward him.
"Have you done this before?" she asked.
"Yup," he replied with a big grin. Just then, he heard the instructor shouting his name over the sound of the airplane engines and the roaring wind. The cabin door was standing ajar, and Zane was waiting for him. John adjusted his parachute, stepped up to the edge of the door, and jumped out into the wide-open atmosphere.
