Continental Airlines will test a Boeing 737-800 fueled partially by biofuel on Janurary 7th. This test flight will be powered with a mix of traditional jet fuel and a biofuel made from algae and jatropha plants. This will be the first biofuel-powered demonstration flight of a U.S. commercial airliner.
