I don't think you even know what you're talkin'about...
Quote:
The fuselage of the SM.79 was made of a welded tubular steel frame and covered with duralumin in the forward section, duralumin and plywood on the upper fuselage surface, and fabric on all other surfaces [2] The wings were of all-wood construction, with the trailing edge flaps and leading edge slats (Handley-Page type) to offset its relatively small size. The internal structure was made of three spars, linked with cantilevers and a skin of plywood.
