An electrical control circuit controls the first means with a first portion of the control circuit being carried by the airborne vehicle and a second portion of the control circuit being carried by the container. The portions of the control circuit are automatically electrically connected to thereby permit the operator of the airborne vehicle to control the operation of the spreader.
