Avro 707A (second prototype) WZ736, preserved at the Museum of Science and Industry, Manchester Avro 707B VX790 in flight c1951 (NASA intake) Avro 707 (also known as Type 707) was a British experimental aircraft built to test the tailless thick delta wing configuration chosen for the Avro 698 jet bomber, later named the Vulcan. In particular, the low-speed characteristics of such aircraft were not well known at the time. Aerodynamically, it was a ⅓-scale version of the Vulcan
