A fuselage is provided including front and rear ends, opposite side and top and bottom portions. A pair of laterally spaced front-to-rear extending elongated support structures are supported from opposite sides of the fuselage with the front and rear ends of the support structures extending forward and rearward of the fuselage. A pair of front and rear tubular wings are oscillatably supported between the front and rear ends of the support structures for angular displacement about axes extending between corresponding ends of the support structures and disposed generally along diametric planes of the tubular wings. The tubular wings include inlet and discharge ends and control structure is connected between the tubular wings and the support structures operative to simultaneously and equally angularly adjust the tubular wings relative to the support structures between upright positions with the inlet ends opening upwardly and horizontal positions with the inlet ends opening forwardly. Motor driven propeller structure is journalled in the wings for intaking air through the inlet ends and discharging air from the discharge ends.
