If you jump out of a plane, and are still around to tell your story, it means that you did not forget to open the parachute, and your parachute worked. Parachutes are critical pieces of equipment for any person in the business of flying. Such people must get fully acquainted and trained on all aspects of using parachutes. Parachutes are used for several purposes. A common use is to safely land people after jumping from an aircraft from a certain minimum height. Other uses include dropping equipment in places where an aircraft cannot land. In times of flood, or other natural disasters, it is common to provide relief through parachutes.
Parachutes are also used to bring aircraft to a halt in a shorter distance. As a sport, paragliding is quite popular where a special parachute is used to manipulate movement and directions while in the air. Using parachutes is a hazardous activity, and the user must be fully trained before being entrusted with the task. The risk involved in any mishap related to parachutes is very obvious – the person will not be around to tell the story. This is why this activity is considered only for the professionals in the armed forces, or for people engaged in this specific sport. Using parachutes is not for the casual sports-person.
A good place to learn the use of parachutes is perhaps the armed forces, where they train complete battalions in the use of parachutes. All aspects of using parachutes are important, including wind directions and wind speeds. Pin-point landing on the ground is considered an important target. The person must land on the feet in a running position, and any wrong fall while landing could easily create severe disability. Perfection in the use of parachutes comes only after regular and rigorous training over months and years. Only then people are deployed to actual missions.
