A personal flying apparatus has a substantially horizontal element having a lower surface adapted to acted on by a wind upwardly so as to produce a wind-generated lifting force, and an inflatable element connected with the substantially horizontal element and filled with gas which is lighter than air so as to produce a gas-generated lifting force, so that both the wind-generating lifting force and the gas-generating lifting force jointly lift the flying apparatus to allow it to fly.
