A parachute system operable with a drogue parachute includes a bridle and kill line connected to a deployment bag at one end and to the drogue parachute at another. The bridle includes a stop carried within the parachute container for suspension of the parachute container by the drogue parachute during free fall. A plate is carried within the parachute container for securing the stop when the flaps are in a locked and closed position by a closing member and ripcord. The ripcord includes a ripcord pin and a ripcord line passing through an eyelet of the ripcord pin and attached at a fixed end to the parachute container for providing a pulley effect and thus a mechanical advantage when the free end of the ripcord is pulled. The ripcord further includes left and right lines carried within a housing and an elastic cord between their free ends for biasing ripcord handles against the ripcord housing. To further prevent an out of sequence deployment of the drogue parachute and main parachute, a safety pin is carried by the bridle outside the parachute container and is connected to the ripcord pin for preventing removal of the ripcord pin from the closing member until deployment of the drogue parachute causes the bridle to pull the safety pin from the ripcord pin, thus allowing the ripcord line to pull the ripcord pin from the closing member only after the drogue parachute has been deployed.
