A parachute arrangement for pin point soft landing air cargo that includes a hand settable time delay cutting mechanism for cutting the reefing line of a cargo attached parachute after a predetermined drag force has been exerted upon a release pin cable. The mechanism includes a ballistic cutting blade carrying a powder charge in alignment with a timer controlled firing pin. A release pin actuates the timer when the cable drag force removes the release pin from its normal position extending in the path of a timer lock member.
