Battling violent storms, forest fire smoke, head winds and fatigue, a pair of Spokane, Washington, aviators flew nonstop across America and back in 1929 to establish a new world record. Their Buhl CA-6 sesquiplane, named Spokane Sun-God, was the first airplane to make a non-stop transcontinental round-trip flight. Sponsored by the National Air Derby Association along with Texaco, who supplied the gas, Buhl Aircraft Company, who provided the plane, and many Spokane citizens and businessmen, pilot Nick Mamer and mechanic Art Walker took to the skies at 6 p.m. and headed west into the sunset from Felts Field on August 15th as a crowd of thousands looked on.
