Claim 8:
9. The aircraft according to claim 8, wherein
each of the port and starboard airfoil assemblies comprises:
(i) primary airfoils extending outwardly from a forward region of the aircraft fuselage, and
(ii) secondary empennage airfoils extending outwardly from an aft region of the aircraft fuselage and separated from the primary airfoils along the longitudinal axis of the aircraft so as to define a space therebetween, and wherein

each of the port and starboard propulsion units comprises an engine and propellers operably driven by the engine to provide thrust to the aircraft along a thrust line, and wherein
the engine and propellers are mounted for pivotal movement within the defined space between the primary airfoil and the secondary empennage airfoils so as to achieve a first operational position wherein the thrust line of the propellers is orientated substantially parallel to the longitudinal axis of the fuselage and a second operational position wherein the thrust line of the propellers is oriented substantially perpendicular to the longitudinal axis of the aircraft.
