VariViggen is a plane designed by Burt Rutan, he named it after Swedish fighterplane Saab Viggen. Elbert L. Burt Rutan (born June 17, 1943 in Estacada, Oregon) is an aircraft designer known for designing light, strong, unusual-looking, energy-efficient aircraft. ... The Saab Viggen (Thunder Bolt or Bolt ¹) or Saab 37 is a Swedish fighter aircraft manufactured between 1970 and 1990 to replace the Saab Draken (Dragon). ...
Rutan'sVariViggen bears more than an accidental resemblance to a Swedish military jet fighter, the SAAB J-37 Viggen, which first appeared during a press preview in 1965 and helped to inspire Rutan to create a canard airplane of his own design.
Rutan was eager to use N7EZ to explore further the performance of the canard layout.
Rutan surveyed the builders in April 1978 and discovered that the average, finished airplane was 14-23 kg (30-50 lb) heavier than specified in the plans.
Rutan's most expensive project, the Beech Starship was just one in a series of experimental and unique aircraft designs that are his trademark.
Rutan's creative vision led to the formation of his own Rutan Aircraft Factory in 1974 to design and market innovative canard designs for home-built light aircraft such as the VariEze and the Long-EZ.
Burt Rutan expanded his successful experiments with composite materials to larger-scale projects with the formation of Scaled Composites, Inc., in 1982, for the design, fabrication, and flight testing of prototype aircraft projects for both the government and private industry.
