The comparative anatomy of the cetacean nervous system

An air cushioned vehicle includes a control system for permitting the vehicle to move sidewards and rearwards and for accurately steering the vehicle during these movements. The control system also permits the vehicle to hover and have full control while the vehicle is under full power. An air stream produced by a power plant mounted on the vehicle body is directed substantially downward to provide lift and substantially horizontally to provide propulsion and steering thrust. Forward and aft vanes are connected to the control system and can be manipulated to deflect the air stream to move the vehicle sidewards. Side vanes are connected to the control system and can be manipulated to deflect the air stream to move and steer the vehicle in the rearward direction and to permit the vehicle to hover while the airstream power plant is under full power.
