Swallow SST

In the years following World War II, British aviation engineer Barnes Wallis — the brilliant aircraft engineer credited with designing the “Dambuster” bouncing bomb — turned his attention to more advanced aircraft designs, including variable wing (swing-wing) aircraft capable of supersonic flight. One of his most famous concepts was the “Swallow,” an elegant tail-less plane he hoped would become the mainstay of Britain’s commercial aviation industry. The Swallow plane had four engines mounted in pairs toward the tips of the wings, one above and one below the aerofoil. These pivoted along all three axes, serving in place of a rudder, ailerons and elevators.
