Abstract: In one form of the invention, a deployment control for releasing a rocket recovery device such as a parachute includes an electrical heating element extensible along a heat-severable reach of an elongate retainer capable of being wrapped closely about the recovery device to retain the recovery device in a compact form until the reach is severed as the result of electricity being supplied to the heating element to thereby release and deploy the recovery device. In other forms, an apparatus for cutting a heat meltable retainer to release and deploy a rocket recovery device includes a heating element extending along at least a short reach of the retainer, and a control device for supplying electricity to the heating element for heat severing the retainer reach.
