The Bonomi BS.18 Airone (English: Heron) was a single seat training glider, designed in Italy in 1936.
The centre section was supported by a low fuselage pedestal and braced on each side with a parallel pair of steel struts.
Its pilot sat in a small, deep cockpit, head against the front of the pedestal and partly protected from the airstream by the upper fuselage panels, which both lifted off for entry.
There was a conventional single skid undercarriage under the forward fuselage aft to the wing trailing edge, with a small tailskid.
The fuselage tapered gently to the tail, where the horizontal surfaces, braced and straight edged but with elliptical tips were mounted on top of a short fin.
