NASA is Painting the Skies Green Over Santa Rosa

NASA and Centennial Challenge partner organization, the Comparative Aircraft Flight Efficiency, or CAFE, Foundation of Santa Rosa, Calif., are encouraging aerospace enthusiasts to attend the Green Flight Centennial Challenge, set to be held at the Sonoma County Airport in Santa Rosa from Sept. 25 to Oct. 1.

Teams from across the United States will test electric, biofueled and hybrid-powered aircraft, vying to be the most fuel-efficient small aircraft in the world. They’re competing for a competition purse of $1.65 million — the largest aviation prize ever offered. / www.nasa.gov.
