The Bach "Super Transport" was a design for a four-engined transport aircraft that was never built.[1]

Design and development

The Bach Aircraft Company was founded by L. Morton Bach in 1927.[2] Following in the footsteps of Fokker with the Fokker F.VII Trimotor, and the metal Ford Trimotor, the Bach Air Yacht was developed as a commercial trimotor transport.[3] In 1928, Bach filed a patent for a four-engined design. The aircraft was similar to the trimotor as a metal-covered, strut-braced biplane, with conventional landing gear. It also featured semi-circular windows like the Stout 2-AT Pullman. The aircraft design featured an unusual modification of the trimotor arrangement with two nose-mounted engines stacked above each other with cockpit windows between them. The fuselage carried a double-decker seating arrangement. The Bach company was reorganized and dissolved during the Great Depression without any examples built.[1]
