A landing system for an air vehicle with vertical takeoff and landing capability is provided that comprises a set of selectively pressurizeable upper and lower air chambers surrounded by a connecting curtain assembly. The upper and lower air chambers are each continuous having elongated right and left cylindrical center sections interconnected by semicircular sections at each end. The landing system is connected to the air vehicle by a catenary system connected to the upper air chamber. The landing system can adjust pressure in each individual set of landing chambers such that the attitude of the vehicle can be adjusted to clear uneven ground or assist with loading and offloading. The system is capable of absorbing energy during vertical landings. After landing, the system is capable of providing suction between the air vehicle and the ground to stabilize the air vehicle.
