Skydiving, , is an activity that involves jumping from a point high above the earth with a parachute to control the descent and landing. The very first parachute jump occurred on October 22nd, 1797, by Andre-Jacques Garnerin, who jumped from a hydrogen balloon from a height of 3,200 feet above the city of Paris. His parachute had no ripcord and it was not packed into a container. The first planned rip-cord operated jump took place in 1919 by Leslie Irvin. The military took an interest in developing skydiving and parachuting technology as a means to save their aircrews during flight emergencies and to allow soldiers to be strategically dropped during battles. Skydiving competitions began to emerge in the 1930s and in 1952 it became an international sport.
