 an aircraft comprising a supporting structure, at least one utility space, at least two propellers whose axles are arranged substantially horizontally, and a driving mechanism to rotate each propeller, the blade angles of at least one propeller of the aircraft being adjustable such that the blow power of the propellers provides the aircraft with a lifting force, and after take-off of the aircraft the blade angles of the propeller are adjusted such that the blow power of the propellers provides the aircraft with horizontal flight.
