Making a few stops along the way, BioJet 1 went 1,776 miles of a 2,486-mile journey from Reno, Nev., to Leesburg, Fla., exclusively on biodiesel. The fuel in question, made by Lake Erie Biofuels, was a blend of soy and animal fats turned to diesel.
The Aero L-29 jet kept the biodiesel from congealing at high altitude by continuously heating it—and landing every 300 miles or so to refuel. The flight is a proof of principle, according to Green Flight International CEO Doug Rodante, and is aimed at addressing the carbon dioxide (CO2) emissions from burning jet fuel -- roughly 3 percent of total worldwide greenhouse gas emissions, according to the U.N. Intergovernmental Panel on Climate Change (IPCC), but released in a very bad spot—high in the atmosphere.
