Camillo Silva designed numerous gliders for Aeronautica Bonomi, but only two of them, the BS.14 Astore and the Biposto Roma were two seaters.
In plan, about half of the span of the BS.24's wing was unswept and had constant chord; the outer panels were straight tapered to rounded tips.
If the aircraft was flown solo it was piloted from the font seat; the occupation or otherwise of the rear cockpit left the trim little changed as it was on the c.g.
Under the fuselage a rubber sprung wooden landing skid ran from forward of the cockpits to well aft of the wing trailing edge.
Its elevators had parallel chord and a central cut-out for the rudder, as this, hinged on the fin's trailing edge, was about twice as high as the tailplane.
