The patent relates to a mooring and landing device for aircraft which are capable of vertical descent for landing comprising an inflatable tube-type device, or trunk, attached to the bottom surface of the craft. 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.
