A parachute works by forcing air into the front of it and creating a structured 'wing' under which the canopy pilot can fly. Parachutes are controlled by pulling down on steering lines which change the shape of the wing, cause it to turn, or to increase or decrease its rate of descent.
All parachutes are designed for one fundamental purpose to slow the gravity driven fall of an object after a person, sometimes in inanimate cargo through the air
