Skydiving is an activity where people jump off from an airplane at high altitude before landing on the ground. While many consider this an extreme sport, it is also used by the military for various purposes.
In sports, parachuting is the term used for skydiving. Here, a group of people jump from an aircraft and perform various aerial maneuvers before landing. While they are airborne, a group of judges watch what they do and score them accordingly. The team that garners the most points wins.
In the military, skydiving was a backup system to save airmen who have to evacuate their aircraft. But years later, this was soon replaced with ejection seats. This did not stop the military from maximizing its potential because they soon realized that this is one way to drop troops quickly into a battle zone.
During the Second World War, airborne troops were dropped behind military lines. This practice is still being done today not only by the regular army but also by specialized units. Outside the military, wildfire fighters are deployed into a remote site if that is the only way in the fire zone.
The history of sky diving dates goes back to the 18th century because this was done by Andre Jacques Garnerin who jumped from this air balloon with a parachute.
To make skydiving safe for those who jump, the gear they use is checked on a regular basis before they board and exit the aircraft. If the first parachute fails, a backup parachute is deployed and sometimes the person does not have to do anything if this is deployed automatically once it reaches a certain altitude.
