Abstract
An apparatus for attaching a load bearing line to a helicopter is disclosed that utilizes a curvilinear track mounted on the underside of the helicopter with a carriage having a cargo hook freely movable thereon. The curvilinear track has a radius of curvature that extends from the center of gravity of the helicopter to maintain forces imposed on the helicopter from a swinging load directed through a point near the center of gravity of the helicopter.
