Abstract	The purpose of this paper is to determine the dynamic tensions that occur in the guylines and pendulum lines of a tethered logging balloon. A scale model was used to represent the tethered logging balloon. During the swinging of payloads, line tensions followed a very predictable sinusoidal curve. It was determined that the maximum balloon displacement will occur when the payload is being lifted off the ground. The maximum balloon displacement corresponds to a worst case position for the system as a whole. The maximum dynamic tensTon that will occur in the pendulum line represented only a 5-10 percent. increase over the static tension to initially lift the payload off the ground.
