The opening of the parachute is much like jumping feet-first into a pool of water. The opening takes about two to five seconds and is not uncomfortable. Square parachutes are simple to manoeuvre and steer to the ground. Steering lines are attached to the rear right and left side of the parachute. By taking the controls in each hand, one steers the parachute by pulling on one control. To turn left, simply pull down the left control. To stop the turn, simply return the control to its original position.
