The trunk is in the shape of a doughnut and the open interior compartment formed by the inflated trunk and the bottom surface of the craft is evacuated to a pressure lower than atmospheric so that the difference between the compartment pressure and the atmospheric pressure moors the craft to the ground. The trunk is inflated to a pressure greater than atmospheric and may be formed with a plurality of holes to provide an air cushion for lubrication purposes.
