Howitt and McCurdy, along with flying club member Jochen Spengler and McCurdy's nine-year-old son Aidan, made the 500-mile trip on Saturday and returned the next day. McCurdy said the engine ran just fine on the biofuel blend. McCurdy, who teaches high-school science in Rhode Island, hopes to take the biofuel airplane on a coast-to-coast flight, perhaps as soon as this summer. His students helped with research and planning of the weekend's flight, he told AVweb, and will also be involved in the next phase.
