An aircraft comprising a fuselage and a vertical fin; a first set of airfoils having the form of a cylindrical wing extending outwardly and for- wardly from the said tail fin; a second set of airfoils in the form of wings extending outwardly and backwardly from a frontal section of the fuselage at a lower elevation than the first set of airfoils; and a third set of airfoils extending outwardly and backwardly from a frontal section of the fuselage at a lower elevation than the first set of airfoils and at a higher elevation than the second set of airfoils. The second and third sets of wings extend outwardly and connect at their tips with the first set of wings by means of streamlined surfaces in order to minimize induced air drag. The first and second pairs of wings along with the fuselage present a double triangle or diamond shape in the top plan view and a partial circular shape in the front elevational view. The third pair of wings presents similar shapes with respect to the first airfoils and fuselage in the top plan and front elevational views. Additionally, a unique wing structure is disclosed for the cylindrical wing where the upper and lower cambers vary along the span of the wing to enhance lift and vertical stability such that the cylindrical wing acts as a lifting as well as a directional component. Finally, a unique separation process of the fuselage and wing structures affords a safe and un-powered descent of the aircraft components in the event of an aborted flight.
