Yup. NOT aluminium, but Stainless Steel. Yes! The RB-1 Conestoga was a twin-engine, stainless steel freight aeroplane designed for the USN during World War Two (2) by the Budd Steel Co. of P.A., U.S.A. Although it did not see service in combat, it pioneered design innovations in post-war cargo aircraft, some of which were later incorporated in modern military cargo planes.
I await oncemorealoft's approval. Excellent post by the way!
