2011 Green Flight Challenge
NASA and the Comparative Aircraft Flight Efficiency (CAFE) Foundation of Santa Rosa, Calif., are holding the 2011 Green Flight Challenge, sponsored by Google, at the Charles M. Schulz Sonoma County Airport in Santa Rosa from Sept. 25 to Oct. 1. The competition's goal is to advance technologies in fuel efficiency and reduced emissions with cleaner renewable fuels and electric aircraft.

NASA's Centennial Challenges Program is providing $1.65 million in prize money to the winners of the competition. The purse is the largest aviation prize ever offered.

To win the competition, an aircraft must fly 200 miles in less than two hours and use less than one gallon of fuel per occupant, or the equivalent in electricity. If more than one aircraft meets the criteria, first place will go to the team with the best combination of speed and efficiency.
