A parachute is a device used to slow the fall of a person or object from a great height. Gravity and air resistance act upon falling objects. The force of gravity is normally much larger than the air resistance on many objects (for example, people).
Parachutes have been used to deliver cargo, as brakes for landing airplanes, and today for skydiving. In BASE (Building Antennae Span Earth) jumping, a very dangerous sport, jumpers jump off of buildings, towers, bridges, cliffs, etc., opening a parachute in the final seconds, just before landing. In most countries, BASE-jumping is illegal. BASE jumpers jump from fixed objects.
BASE jumpers have to come up with newer equipment designs and parachute packing and deployment methods because BASE-jumps take place close to the ground. BASE jumpers have developed quicker methods to get their parachutes to open quickly. They have developed "highly specialized" parachute equipment and packing techniques.
Austrian BASE jumper Felix Baumgartner has lived his life on the edge. He has spent his life jumping off huge structures and parachuting to safety. He makes jumps in movies like "Triple X" and "The Fast and the Furious." He is said to be the first man to jump off of the Petronas Towers (451 meters) in Malaysia (the tallest building in the world). He has made more than 2,600 parachute jumps and 130 BASE jumps.
One technique the military uses is static-line jumps. Static line jumps are done low, about 305 meters or less, and they use round parachutes. This technique deploys a large number of troops into an area in the quickest manner. HAPPS (High Altitude Precision Parachute System) or "stealth parachutes" are military skydiving rigs that cannot easily be seen from the ground.
