A payload or cargo is delivered from a cargo hold of an aircraft during flight, by orienting the fuselage into a nose-up and tail-down position of at least 30 degrees off horizontal, and lowering the cargo from a cargo hold in the fuselage by means of one or more lines. Preferred vertical takeoff and landing (VTOL) aircraft include tilt-rotor or tilt-wing aircraft, and especially preferred aircraft are capable of generating control moments with their rotors to assist in orientating the fuselage of the aircraft into a nose-up and tail-down position.
