An apparatus is provided for rapid loading and unloading of large volumes of liquid to and from a cargo transport, herein a landed aircraft transport. At a ground station, liquid is loaded from, or unloaded to, a reservoir equipped with a positionable, extendible hollow tubular boom having a cross-sectional flow area exceeding thirty square feet. At the extendible end of the boom, a valve closure is provided, movable by a power-driven ball-screw actuator between a retracted position closing the open end of the boom and an extended, open position spaced forwardly of the boom end. A cooperating valve assembly and receptacle for receiving the positionable boom end are mounted on the aircraft in a wing section, accessible by a fold-away hinged wingtip. A movable, normally closed valve closure of the aircraft valve assembly is opened by an axially movable central plunger mechanism, engagable and axially displaceable by articulated fingers on a forward face of the boom valve closure, such that the plunger is depressed inwardly of the aircraft valve assembly as the boom is moved into place. Thereupon, the boom valve closure is opened by the power screw actuator.
