Scaled employees grew from a handful to hundreds. Increasingly, projects were assigned to lead engineers, with Rutan supervising. Global Flyer, for example, the single-engine jet in which the late Steve Fossett, flying solo, first duplicated and then surpassed Voyager’s achievements, was designed and built with little of Rutan’s direct participation. But certain designs, entirely his own, represented the continuing evolution of his ideas about personal aircraft. One of these, Catbird, originally intended as a CAFE efficiency racer and also studied as a Bonanza replacement, was a very compact five-seat three-surface machine that achieved a 215-knot cruising speed with a turbocharged 200 hp Lycoming engine. It succeeded the Defiant as Rutan’s personal airplane until he cannibalized its engine for his next personal-airplane project, Boomerang.
